DOUG MATTHEWS  running version 2.2 on Snow Leopard (clean install) with absolutely no problems; this app does it's job well and I feel so much safer knowing I've got Little Snitch turned on, I never felt very safe running the OS X firewall  
(Version 2.2)

MATREYA  This is a very useful app, but the price seems a little steep for Shareware.  
(Version 2.2)

JIA123  How to uninstall Little Snitch 2.2 completely from Mac OS X? I deleted the application, preferences already, but it's still there, prompting access/ deny and monitor my network. Someone please teach me how to solve? THANKS!

Teach me by any means, or ways. Email or somehow, thanks!!

Email me: Jia123_88@hotmail.com  
(Version 2.2)

PHILIPNI  Great app !  
(Version 2.2)

RON BELL  Such an option would have to be a manual one, or at least defaulted off. To have it otherwise would be contrary to the function of the app itself!  
(Version 2.2)

LOUNGE DELUXE  I reckon it's about time now to build some sort of automatic or manual update functionality within LS. C'mon Obdev, even all of the freeware apps I currently use are able to do this.   
(Version 2.2)

KOBALT  I've been running beta1 since it became available and have had no issues what so ever. As far as I'm concerned a LS beta is as good as a final release ... bit like 1Password in that respect. :)  
(Version 2.2b2)

MACTECHHEAD  I love this handy tool.

But I have one giant complaint. Version 2.0.5 was the last version that worked properly when logged in as the System Administrator.

Every since version 2.1 to now the root user has no rules, you cannot import any rules and even attempting to use the default rules results with a blank set of rules.

Permissions repair does nothing nor deleting the folders Little Snitch uses .  
(Version 2.1.4)

RIDOGI  I tried this long ago and found it to be unstable. It has matured nicely and I find it to be lightweight, stable and fully featured to control the connections going out of my Mac. Excellent!  
(Version 2.1.4)

DHESS01  Global rule setting is a HUGE improvement! Now just needs a check box to set as global in the rule-setting popup window.   
(Version 2.1.4)

BS0D  I really like Little Snitch. It is NOT INVASIVE at all, it runs discreetly in the background and it it very safe.

Much less invasive than NetBarrier X5 for example, which harrasses me with pop ups when I set it to max protection... and all it does is the same job as Little Snitch (except it has more options).  
(Version 2.1.4)

M2  There's a minor bug in version 2.1.3 (potentially not fixed in 2.1.4 either). If you are running Parallels, Little Snitch will block attempts made from Parallels to use the Mac network for the guest OS. However, there is no allow/deny dialogue for this so Parallels outputs an error about psl and quits.

Very annoying but if you turn off Little Snitch, Parallels will launch fine.  
(Version 2.1.4)

Is there an easy way to do it?  
(Version 2.1.3)

SJHA  I also had the problem of a hang at the log-in window.   
(Version 2.1.3)

SHKING  Couldn't reboot after upgrading from 2.0.4.

I rebooted in Verbose mode and found that it hangs while starting the Login Window Application.

Rebooted Safe mode and reverted back to 2.0.4  
(Version 2.1.3)

U P 2 U  1. Unstable, even the Installer will crash... have no word to say.

2. The background App SLOW down my Mac OS. In many case, edit the hosts to block some site is good enough.

3. Not smart enough.  
(Version 2.1.3)

SHOTGUNWEDDINGS  Excellent product, does the job very well and timely updates when serious issues arise.

Thanks for a great product

As for the commentor below, I use 10.5.7 and it doesn't forget my rules. Try repairing your disk permissions or repair your hard disk. Its something on your end causing that.  
(Version 2.1.3)

EGN  After 10.5.7 update LittleSnitch "forgets" rules specially on startup and shutdown and does not seem to record them for each time I shutdown or turn one of my macs on this happens. On Intel as well a G4.  
(Version 2.1.1)

BONI  thx to PLOINKRE, this second nightly build fixes the annoying mDNSResponder alerts and saved my nerves. :-)

ANDRESKS  Excellent application, I think this application is the most easiest way to have everything under control between your Mac and the Web. You can see what goes INto your Mac, and most importantly, take control of everything that can go OUT on the web, and the best of all is the excellent support! from developers.  
(Version 2.1.1)

BONI  i was wrong! the nightly build doesn't fix the annoying mDNSResponder alerts on my imac either! I have two macs with OSX 10.5.7 now. I have to quit little snitch on my both macs and have to wait for another nightly or day build little snitch update. :-(  
(Version 2.1.1)

BONI  the nightly build Fixed a bug which created a lot of mDNSResponder alerts on my imac. but didn't solve anything on my macbookpro unibody. Got OSX 10.5.7 on both macs now. Have stop little snitch om my MBP. Too annoying.  
(Version 2.1.1)

SHMK  Tried to upgrade form 2.0.5 and I kept getting a message "This installation of LS is broken" couldn't seem to get it to work with repeated installs trashing the preferences etc so went back to 2.0.5 and everything is normal again. Contacted developer as well.  
(Version 2.1.1)

MISU  it is fixed in the nightly builds :-)

BONI  Jeezes, since this update i have to allow mDNSResponder a dozen of times when quiting or restarting my imac and macbookpro with osx 10.5.6. mDNSResponder is a protected rule so i can't change a thing! Do i have to reinstall the earlier version of little snicht for this? :-(  
(Version 2.1.1)

SALAMIJAKK  This program led to the downfall of eyeTV signal and the TV viewing is up. Fortunately, the removal and two Onyx pursuing rescued.

(Version 2.1.1)

LEMERLOT  Still old security bug! Although Little Snitch's preferences should be LOCKED to provide security they are UNlocked when my Powerbook restarts UNTIL some seconds after starting up have passed by.

To be clear: After some seconds it locks itself automatically - BUT it's open before so there's no security when the computer is starting up! This happens even with the new Little Snitch 2.1.1. (running Mac OS X 10.5.6).

I filed that security relevant bug 5 months at the developer ago but unfortunately it's still part of this recent version Little Snitch. That's why I have to rate it accordingly.  
(Version 2.1.1)

ANDRESKS  Unable to install this version (2.1.1) in my computer, the installer crash...

GMAPPER  I have a licensed copy of LIttle Snitch and it pretty much works as it is supposed to work. I use it whenever I add software that I'm a bit uncertain about, to see where it phones home.

What I can't understand is why all of the comments and reviews that are anything other than complimentary are getting consistently marked down in the comments. While the reviewers come to a somewhat negative conclusion, their remarks seem well thought out and even-handed. These are not trolls just hammering the software for no apparent reason, so why bump them down?

Makes me wonder if the negative marks are well-meaning fanboys who will hear no evil about their beloved Little Snitch, or if it's part of an effort by the developer to push negative reviews down the list. I trust that it's just fanboys, but they aren't doing the developer any favors.

Let's give the software on MacUpdate our honest assessment, and let the individual make the final decision about whether or not it's right for them.  
(Version 2.1.1)

MACTICK  I have had none of the problems cited by Flatpicker with any of the versions of Little Snitch. The LittleSnitch Uninstaller removed everything except to plist files (at.obvev.littlesnitchconfiguration.plist

at.obdev.littlesnitchmonitor.plist) and I found nothing else left on computer, using both FindAndFile or EasyFind. I assume not deleting the 2 plist files is deliberate, as it permits upgrades without having to re-install serial number or change configuration.

  
(Version 2.1)

FLATPICKER  Last week, I thought I'd finally give LS a try. It worked as promised and, as I'd be warned would happen, the constant prompts and warnings drove me nuts in less than a day. I don't doubt that the software is well engineered -- perhaps too well. I decided I wanted it gone, and carefully followed the uninstall instructions by using the uninstaller contained in the package, and then rebooting. Result: LS, though invisible to conventional searches, continued to function, but at the cost of hangs with both Mail and Safari. I couldn't shut it off; I couldn't get rid of it. As I'd already followed the uninstall instructions, I tried everything I could think of: repairing permissions with DiskTool, rebooting in safe mode and running AppleJack (the auto/restart thing), rebooting again in safe mode when AppleJack didn't fix the problem, and then running /sbin/fsck -fy, rebooting and trying Onyx (which froze imediately), rebooting and trying MacJanitor (which froze immediately) -- you name it.

By this point, I was seriously angry, and wrote an email (through webmail in safe mode) to OD's customer service department. I received an email back fairly promptly, in which the rep indicated that OD "is not aware of any problems with the uninstaller" except in cases where one tries to use the configuration routine to uninstall or doesn't reboot after a proper uninstall. Now, since a simple web search discloses plenty of people complaining about the LS uninstall, I have to assume that OD is either clueless, or deliberately avoiding the problem (for whatever reason).

In the meantime, I found EasyFind, which installed painlessly and promptly located all remaining traces of LS, including the LS kernel, which the uninstall leaves active. All the remaining files were located in hidden/protected folders and are normally invisible in Finder. OD seems to want users to believe that the location and persistence of these files and the problems they cause is some kind of bug -- one that the rep said they'd like to know about so they could "debug" it. Given that a simple web search for problems yields multiple hits, I'm afraid I simply don't believe that the folks who were capable of creating LS in the first place are that inept, or that they're unaware of the problems. The kernel doesn't "accidentally" remain active in a hidden file after one has followed proper uninstall instructions to remove the program. My system is now back to normal, thanks to EasyFind, and the odds that I'll ever use LS or any other OD software again are exactly nil. If the quality of a piece of software is to be measured by the workability of ALL its components, then I can't give LS any rating higher than 3, and that's only because it does do what it's billed to do. Don't want to say how I'd rate the company, as I'm trying to cut down on cussing. I do know that I don't trust 'em.  
(Version 2.0.5)

FLOOCE  I used little snitch 1 and 2 for quite some time, but now decided to stop with it.

When I reinstalled little snitch 2.0.5 lately, it completely crashed my system, which I couldn't boot anymore. Drive and permissions repair from OS-DVD didn't help. Luckily I made a time machine backup 10 minutes before the crash, but needed to reinstall my system!

LittleSnitch is past for me from now on. No use and potentially dangerous. If you get malicious software, then they can hide their activities by using the connection of a browser or something. For normal programs, well of course it is nice to control the home-phoning, but seriously, after I had it for a couple of month, I found that there is nothing to be worried about other then automatic update control, which was pretty much it that was requested.

If you find use for it, despite the problems with uninstall, despite the deamon and kernel-extension running, despite the fact that malware can find its ways anyhow, and IF it doesn't crash your system, then it is an alright tool for controlling and monitoring network activity and see what is going on. The GUI is alright, would be better if the functionality could be turned on/off, and the way the rules are set is alright as well, with enough options. Nothing for beginners though.

All in all: Can't recommend it.  
(Version 2.0.5)

PXL  Ever since I installed the latest version, it has screwed up my Apple Mail. I can receive but cant send emails. I uninstalled LS and mail worked properly. Went back and installed version 2.0.4 and mail worked properly. Anyone having mail issues?  
(Version 2.0.5)

CORPSECORPS  It's simply a must-have Mac tool for peace of mind when it comes to knowing which apps are doing what on the net with and without your knowledge!  
(Version 2.0.5)

YAZSOFT SUPPORT  Absolutely terrific utility; no doubt about it and worth every penny.

Highly recommended.  
(Version 2.0.5)

CITIZENVERN  I've been using Little Snitch for probably 2 years now, and finally shelled out the meager price to own it. It's well worth the price for the peace of mind it offers. I tried a similar program, i forget which one, and although it seemed formidable i stuck with Little Snitch for its simplicity and ease of use.

Little Snitch has the basic features needed to tip you off to when some program's trying to silently connect to the internet. The only problem, the reason i marked it down for features, is that most of the time the alert is that some obscure program is trying to connect to some obscure site for some mysterious reason. "Alert! Blah blah blah.something wants to connect to blahblah.appleorsomething.blahblah on port 80!" So, if anybody at Objective Development is reading this, i have a suggestion that i hope can find its way into reality: An ever-expanding database of known port activities, similar to and including the databases kept for virus definitions, that would explain better what's going on and wether it's a goodish or baddish thing. Now THAT is worth at least a 5 and i will gladly buy a new version to get it!   
(Version 2.0.4)

ROBOBOT  For anyone else that has problems removing the UIAgent after uninstalling Little Snitch:

I had to open up a terminal and open launchctl.

enter "list" to see the daemons controlled by launchd.

I had a LittleSnitchUI daemon as well as a LittleSnitchNeworkMonitor daemon, even after I uninstalled!

Enter remove for each one you want to remove.

What a pain!  
(Version 2.0.4)

POTATOPEELER  If you ever wanted to turn your Mac into something that constantly bugs you a la Windows Vista, then Little Snitch is the program for you.  
(Version 2.0.4)

RONAH  I downloaded it as part of a gifted bundle special from MacUpdate, but when I went back to get the registration code to register it after I restarted the machine, it had disappeared  
(Version 2.0.4)

ANONYMOUS  I have just updated from Little snitch 1. The application works fine as it did in version 1. However there was a big surprise: unlike indicated in the on line documentation of the upgrade, little snitch is no longer in the prefpane of the system. There is now a small (ugly) icon in the main menu bar. If you miss it, you may think that you have all lost both the old and new LS versions.

An obvious additionnal feature is that you can see easily the IP and activity of the remote servers you are connected to. The other improvements are latent, meaning that you do not have to know them if you do not specifically need to.

Concerning the VAT, I am surprised that non-european firms accept to collect the VAT for foreign countries. Do they get paid for it ? If not, why do they accept the additional "free" work ? Strange...  
(Version 2.0.4)

MYDRIVEC  I have used many new programs and software firewalls. In my opinion, Little Snitch is too detailed and stops too much traffic. Instead of just at an application level.

Further, there seems to be no way to turn off the program or limit it for other less technical users.

I had to spend the first day looking over my wife's shoulder to ensure she choose the right permissions. The very same ones I had chosen under my profile.

Anyway, if you have a one user machine or truly do want to micromanage your internet, this is the program for you.  
(Version 2.0.4)

THM19A  Hello. (abouth litle snitch)

I by 10 program from Macupdate - one Litle snitch - but I dont have the registrasion number too get it going? Can I get help?

It can bee send too my email turehm@hotmail.com

Hope for answers..

Thanks..   
(Version 2.0.4)

GABRIEL2575  very difficult to obtain the SERIAL NUMBER for it

and quit the demo format  
(Version 2.0.4)

MISHA  I've been using this since it first came out... there's nothing else like it on the Mac. It's definitely a power user's app—grandma probably wouldn't be able to figure out the prompts it displays or what to do.

But if you know anything about network security and want to make sure that nothing on your Mac is connecting anywhere it shouldn't be, LittleSnitch is terrific.   
(Version 2.0.4)

SMTIPS  You know, if people would RTFM they wouldn't come here talking garbage like this. Get it right...Little Snitch INCLUDES INSTRUCTIONS on disabling/removing it! Try looking at them before giving it poor comments.  
(Version 2.0.4)

MSWFUJOWDFFYC  Try this:

sudo ipfw add deny all from 216.71.206.78 to any

eh eh eh YOU LOCK the locker  
(Version 2.0.4)

CH5719  The issues i had with 2.0.4 (described below) were fixed with build 2.0.4.386.

Very fast support. Never really had a problem with the app before, so here's my rating.  
(Version 2.0.4)

CHRISDPRATT  This app is effective at letting you know when other applications are attempting to access your network connection or "phone home". However, it having some default filters for standard Mac OSX applications and processes would be nice. You wouldn't believe the number of miscellaneous daemon apps there are. Additionally, sometimes it failed to remember permissions I'd already given an app and would ask me again.

That said, the UI is a huge monumental failure. Once installed, there's no way to stop it from loading at startup or close it. To be fair, in normal operating conditions you probably wouldn't want to anyways, but I was running the trial which *annoying* interrupts you every 3 hours with the configuration dialog and makes you restart it. Actually, that was enough to turn me off. If you're that worried about making people buy your software, use a time-limited demo or something.  
(Version 2.0.4)

CH5719  Version 2.0.4 seems to have problems. My console logs report a lot of crashes of the UI agent.

Also, some apps aren't able to connect since LS seems to assign weird process ids to them and can't utilize rules there.

Disabling LS fixed this, but since this is not an option for me, i switched back to version 2.0.3 which didn't give me any issues at all.

Hope they fix this soon.  
(Version 2.0.4)

CASTLE  Shame they don't have a better payment system. I just went to register a license only to find that by the time they add the tax (which I never usually have to pay when buying software) and the processing fees all of a sudden I'm being asked to pay $40, not $30. Nah.  
(Version 2.0.3)

GURUBEZ  Great App!

I ve paid with plesaure for this Software.

  
(Version 2.0.3)

BABYFETT  Does pirated software really phone home and if so, so what? How can they catch you?  
(Version 2.0.3)

IT2BE  After de-installing a trial I also have 'Little Snitch UIAgent' running.

Even after removing all elements I found.

Where do I have to look to get rid of it because it really very very active (too active imho)...  
(Version 2.0.2)

PARADIGMLIE  You need to run the activity monitor, and then find it and stop it. Or just take it off your startup items and then relog. either way, its not hard to stop.  
(Version 2.0.2)

IPECK  I've deleted the app, and the "little snitch UIAgent is still runinng. I've searched for it but cannot be shown in spotlight.. This app leaves crap behind when deleted, be careful. Im not happy with this  
(Version 2.0.2)

HELIOS9  Hmmm...wonder if the kernel panic issue is particular to Leopard only?

Are there any folks running Tiger that have experienced it?  
(Version 2.0.2)

ISILVER  I emailed ObDev earlier about the kernel panics, just received a reply ...

[quote]We appologize for the inconvenience. In rare cases this kernel panic happens during unloading the kernel module of the previous version. This bug is already fixed within 2.0.2 and will not happen again during the next update.

Kind regards,

Karl Schwarzott[/quote]

It doesn't seem too rare though, posts about the problem here and at there forums ...  
(Version 2.0.2)

PISSNAROUND  in demo mode, once the 3 hrs times out and the dialog pops up to remind you your time has expired, and you click the restart demo mode. the configuration program locks up, spinning beach ball etc

didn't happen in previous versions  
(Version 2.0.2)

TWELVEIGHTYONE  Hi there,

I too got a Kernel Panic after updating to 2.0.2 but it happened when Leopard was updating cache files.

After forcing a restart, all is well.

2.0.2 is a worthy upgrade. I am guessing Objective Development will make a small update to the installer to prevent the Panic, but it does not affect the actual installation of Little Snitch.  
(Version 2.0.2)

HELIOS9  Installed LS 2.02 over my preexisting v2.01, restarted my Powerbook and NO problems whatsoever. Everything's smooth as silk, here.

OS 10.4.9.  
(Version 2.0.2)

COLLIN BLACKMAN  decided to update to 2.0.2 and after installation when selecting restart - Kernal Panic. So ran .dmg again and uninstalled LS and loaded 2.0.1 back. Heaps of activity with mds and mdworker in Activity Monitor with 2.0.1 running and then another Kernal Panic. My advice flag 2.0.2 as all was well with LS until i upgraded.

A J BENAMU  Kernel panic on 3 mac, 2 Intel, 1 PPC when restarting.  
(Version 2.0.2)

MUDFLAPPER  I love Little Snitch.

It's rock-solid. The new interface is attractive. The UIAgent and the Network Monitor only use about 6MB of memory, each, and neither of them hog the CPU. In fact, I've never seen CPU usage rise above 2.5, and that's only when the Network Monitor window is open.

It's a little on the expensive side but I purchased it on sale though a promotion so I'm not complaining one bit. Besides, I'd rather have some piece of mind than a couple more bucks in my wallet.

Thanks to the developers for this great app.  
(Version 2.0.1)

IGREG  This version of LS is bloated up with eye candy and unnecessary menu clutter. It is also more resource/memory hungry than the Preference Pane version.

System-wide monitors and security programs belong in System Preferences.  
(Version 2.0.1)

MILCKYWAY  Great application. I recommend to block Quick Time Player's port 554 rtsp.  
(Version 2.0.1)

JUSTIES  A must have tool on mac.

You would like to know, which app phones home? Then test this tool!  
(Version 2.0.1)

GARY30  I really like the new UI for Little Snitch. It shows information in a way i can understand better and makes it easy to edit rules and evaluate existing ones. Very small system overhead from what I can see. I wouldn't boot my Mac without it.

MacBook Pro OS X 10.4.11  
(Version 2.0)

LEXTEXTER  VERY useful :-)  
(Version 2.0)

PAULNOJUSTPAUL  Very nice peace-of-mind utility that's in a class of its own. I first bought this (v1) as part of the MacUpdate/MacHeist bundle a little while back. Version 2 adds a nifty network monitor and a nice revamp to an already intuitive interface.

1.x users note: if your key begins with 32 you get this version as a free upgrade, thankya ObDev!  
(Version 2.0)

DELTA FARCE  Very good software. Necessary for security. Not to mention, there's virtually nothing else to compete with it that works. Still, they did nice job of the major 2.0 update. One of the first installs when setting up a Mac.  
(Version 2.0)

PAT320  I've reinstall version 1 , LS2 is to boring to use IMHO.

Otherwise , I think that developper will install in their software something to detect LS and force user to create a rule.

The game "Zuma Deluxe" detect LS and doesn't launch if I refuse to him internet connection for exemple.

What is the future of LS ?  
(Version 2.0)

TAKA^2  This software was always good. The new version is much better, though. It is one of first things to install every time to rebuild a Mac.

Gary30, I am curious what you are talking about, though. I don't know that problem. But, you are implying that the new 2.0 versions DOES block every application, so the problem is fixed?  
(Version 2.0)

GARY30  I recently installed Leopard and the new version of Little Snitch (2.0). In trying to grok the new firewall situaiton I visited the Objective Development forums and to my shock I discovered that Little Snitch does not and has not in the past monitored/blocked all outgoing connections from third party apps.

I am floored. I had trusted this application for years. If there are third party application developers that have figured out how to get around Little Snitch, then how long will it be until spyware developers can do the same thing. I am very concerned about this.  
(Version 2.0)

TWELVEIGHTYONE  A great piece of software, like others have said before I really like the new interface and the fact it is now NOT a System Preference.

Rules are easy to configure, understand, edit and delete if not needed. But I really like the fact I can see easily whenever anything is trying to send data FROM MY MAC to somewhere I don't want it to go.

All you need is Little Snitch. Thanks and Kudos to the developers.  
(Version 2.0)

FARIBORZ  It goes without saying that Little Snitch is one of the best Mac software around if not the best. Anyone who cares about the security of his personal data being transmitted to unknown sites should give it a try. It works flawlessly in the background and pops out only when there's a risk of an unauthorized connection with an external source. The new version is packed with new features and its interface is really friendly and helpful. I highly recommend it to all serious Mac users. Fariborz AMIRSHAHI - Verona (Italy)  
(Version 2.0)

JFM  Excellent! a real step forward compared to the previous version, not only the interface, but the very clear (and not too intrusive) way of keeping an eye on outgoing/incoming traffic. It is definitely worth the price of the upgrade!  
(Version 2.0)

SHAAHIN  It would be great if you could optimize the Network Monitor icon on the menu bar, also giving the user a variety of different indicators, not just one.  
(Version 2.0)

G4JAY  For some reason, it kills my Airport Base Station. Using Little Snitch for about an hour will make the the signal weak and eventually lose the Base Station completely. The only way to get it back is resetting the Base Station. After disabling Little Snitch, I have not had a problem.  
(Version 2.0b10)

FERRUCCIO BUSONI  Little Snitch Network Monitor uses about 1% of CPU about when it is first started, then gradually builds up to 5% - 10%. I am running 2.0b10, which says it fixed a problem with Little Snitch Network Monitor... was this the problem? Either way, it's still there.  
(Version 2.0b10)

OBJECTIVE DEVELOPMENT SOFTWARE GMBH  Little Snitch 1.x does NOT work on Mac OS X 10.5. Leopard's kernel layer has changed significantly, which made it necessary to rewrite large portions of Little Snitch's network filter architecture in order to make it compatible with 10.5.

Regards, Norbert

Objective Development  
(Version 2.0b10)

ASSPROPHET  I did an upgrade install of Leopard, and LittleSnitch 1.2.2 is working fine on my system... why are they blocking me from installing 1.2.4 on Leopard?

I'm wondering if this is a ploy to force users to upgrade. Any one else know what's going on here?  
(Version 2.0b10)

MAGENTIS  No, Leopard doesn't block outgoing traffic, only incoming. Little Snitch is still very relevant.   
(Version 2.0b10)

SAPPOROBABY  Doesn't this application become irrelevant tomorrow with the release of Leopard? I was going to spring for it but I will wait until Leopard and see what happens with this. I will uninstall my current version of LS, and see how Leo handles Internet traffic.  
(Version 2.0b10)

SMOKEONIT  works now!  
(Version 2.0b9)

THUNDERCLAP82  While this is probably a great piece of software for those concerned with what is coming and going from your Mac it wasn't for me. After installing it I felt I was on a Vista machine with all the popups and confirmations I had to select.

THUNDERCLAP82  I tried installing this program and like others have commented the installer doesn't work.  
(Version 2.0b9)

MAGOSILVAN  Installer doesn't work on my G4 1.25 DP (OsX 10.4.10).

S P L A T !  yeah!!!

installer dont work for me too!!  
(Version 2.0b9)

SMOKEONIT  the beta9 installer don't work... uninstall does, but not the install function, weird...  
(Version 2.0b9)

PHALERON  Is there anywhere one can find out what new Little Snitch 2 introduces over the previous version? I looked at the developer site but could not find any info.  
(Version 2.0b9)

NONEOFYOURBIZ  Did anyone notice that Leopard is going to have Little Snitch functionality built in?

Thank you for your service Little Snitch, may you rest in peace.  
(Version 2.0b9)

SMOKEONIT  let's see if this beta update eats less processor speed...

otherwise i don't look back to the old version:-)  
(Version 2.0b8)

TOM MARVOLO RIDDLE  The new Application Interface is so cool!

Keep up the good work, OD, Thanks!  
(Version 2.0b7)

PLASTERPYRUS  I still like the old version, I like the preferencepane. I like the fact that it was easy to use and very intuitive, when an application tried to call home the pane would pop up and ask do you want to let it call home allow or deny pretty easy. Now it displays a bunch of information that I don't know what half of is.  
(Version 2.0b7)

GARYI  The system extension "/System/Library/Extensions/LittleSnitch.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.

I tried a couple of times.

Oh well.

Macbook, running latest OSX. No previous little snitch.  
(Version 2.0b7)

JOHNNY ROCKET  works great so far. CPU usage is currently sitting at 0.10%, peaked at about 4% when a new application accessed the internet and little snitch was waiting for me to tell it what rule, then it dropped back down to 0.2% cpu until the app stopped accessing the internet at which time it's cpu went back to 0.1%  
(Version 2.0b7)

SMOKEONIT  with network monitor it eats a lot of processor speed. like 5-10%...

i run it on my macbook pro...

network monitor turned off little snitch uses a little more processor than the old version...

overall i like the version very much...  
(Version 2.0b6)

BEN_MARKO  Has a lot of trouble with distinguishing between apps that use multiple ports and those that only use one (or two). When you have to constantly set preferences for an app that uses multiple ports due to CONSTANT pop-ups from Little Snitch, it can get to be a....REAL PAIN IN THE BUTT. Other than that, it works as advertised.

The beta you can get from the developer's website shows a much improved GUI, that seems to overcome this serious shortcoming, as you can set Little Snitch to now ignore attempts by app (thereby bypassing all of those repeated pop-ups), and not just by each individual attempt itself. The downside is that the beta WILL erase all of your prefs from the previous version. A further (huge) negative is that I kept getting pop-ups that seemed to come from something called "named" and something called "nttsup." I had no idea what these were, if I should allow them, or what...? I tried to uninstall the beta and it basically did something to my internet connection that kept me from...well, getting to the internet at all.

I seriously hope that LS isn't going the way that Spamfire did, from a once great app to an overdeveloped lemon.  
(Version 2.0b6)

MARKOH  So does Little Snitch 2.0 also get bypassed by certain apps?

MEATMCGUFFIN  Love the new look but please could we have a setting to put the network monitor underneath all windows on the desktop level. It's too distracting on top but really useful. Everything else is perfect, thanks :)  
(Version 2.0b6)

8OO8  Well, my panning of Little Snitch's developer's ethics, below, was totally unwarranted and unfair. I was reminded that LS was also included in July's MacUpdate bundle, which I also had purchased, so I did get the version 2 upgrade without charge. The fact that the developer agreed to participate in both February's Promo special as well as July's bundle speaks well of him. But yes, I guess he did have to draw the line somewhere regarding a free upgrade.

I apologize to the developer for unfairly impugning his ethics, and I fully retract my negative comments regarding them.

A public stoning of myself will be arranged as punishment for my egregious comments. All are welcome to attend. Stoners are particularly welcome. Stones will be provided.  
(Version 2.0b6)

KAYEL  Does anyone else find it a bit disturbing how much memory v2 uses compared to v 1? Otherwise it is vastly improved. I hope the memory can be reduced in future versions.   
(Version 2.0b6)

8OO8  Little Snitch is is a fine app, but what I find a bit hard to take is their business ethics, i.e., their free upgrade only for those who purchased LS after February 15th, 07. Without doubt that cut-off date was chosen intentionally to get another $12.95 from Promo purchasers. The MacUpdate Promo was on Feb. 12th at 40% off. The upgrade to v.2 is 12.95.

Now, paying $12.95 more is, in itself, not a big deal. But I'm sure, though, that Little Snitch's developers already knew when they arranged for the Feb.12th Promo that they could get another $12.95 from Promo purchasers several months later; version 2 was already being prepared for release several months hence, right? Shrewd......but slimy none the less.

I'd really be interested to know how many people purchased the Promo on Feb.12th. Multiply that number by $12.95 and that's the amount of additional money that the developers stand to gain. I'd say that most Promo purchasers will buy an upgrade....I will. But I think that the developers' ethics stink. Feh!  
(Version 2.0b6)

MARKOH  Little Snitch 2.0 is brilliant!!!!

If any of you here should have already bought a license for LS 2.0 and it won't accept the new license number just download the latest beta again:

http://www.obdev.at/products/littlesnitch/download.html

I had this problem but the support amazingly fast =)  
(Version 2.0b6)

KAGAMINOKO  Currently testing out the beta. So far it's running smoothly, no hiccups as of yet. I am just a little disappointed that I would miss out on the free upgrade, since I purchase my current license under the MU promo just 3 days before the cut-off. Perfectly reasonable, since I did get a good discount off it, just that "missing out" so close makes it a little hard to swallow.  
(Version 2.0b6)

HENRIKTEKNIK  Version 2.0bx (I'm currently using 2.0b6) seems to work flawlessly! Not a single glitch or bug as far as I can see.

I love the way it has evolved since version 1.x. One thing would be great to improve, though. I'd like to be able to drop applications onto the image well when adding a new app (disclaimer: I'm not sure if that's in the works).

This is one of the few apps I gladly give 5 stars in all cathegories (save for when I'm receiving bribes).  
(Version 2.0b6)

PICON  I suppose it was too good to be true. My license, along with many others I'm sure, was purchased on Feb. 12th, 2007 at a discount through MacUpdate. I guess I'll have to shell out another $12.95 to upgrade. The product itself is excellent!  
(Version 2.0b6)

A J BENAMU  AWESOME!!!!! Good job. Love it.  
(Version 2.0b6)

IWEDLER  First, Little Snitch is amazing. One of the best utilities for the Mac. It's highly recommended for everyone.

My only wish for a later version is, it should not only display the network activity, it should display the traffic values, so i don't need MenuMeter or NetMonitor.

The only "Negative" about version 2:

It's not a PreferencePane as before. It's splitted into 4 apps, and each eats some of my (limited) ressources.

-> v1.2.4: 1 process = 33 MB real Memory

->v 2: 3 x 32 = around 120 MB real Memory (so i remember)

That's too much for my PB G4 with 512 MB  
(Version 2.0b6)

DONMONTALVO  I'm sooo used to having LittleSnitch installed that I take it for granted it's built into OSX. Works like a charm - always there to protect you - has ZERO issues. One of the best heaps of code out there.

WRELEVEN  Awesome new beta!

I upgraded my version 1 key once I saw the screenshot. Works flawlessly and has a bunch of new network traffic features that will make any paranoid geek squeal with glee.  
(Version 2.0b6)

SPECTRAL7  Quite frankly brilliant, have been using this for years , rock solid and very useful.  
(Version 2.0b6)

WJB3WVU  How do I "uninstall" this program? I've trashed everything I can think of using "Appdelete" and I still get the following security alert from Little Snitch:

Application "finderpop-daemon" (1744) attempts to inject and execute foreign program code in "Finder" (107). This is a security risk as it may allow "finderpop-daemon" to circumvent Little Snitch.

To disable this alert, go to Little Snitch's Preference Pane, click the lock to authenticate, choose "Preferences" from the Action menu (gear wheel icon) and uncheck "Enable Code Injection Alert".  
(Version 1.2.4)

ERASERHEAD_UK  Nice Application, however it would be better with an expanded whitelist, applications like Camino and Transmit really should be allowed through by default.

It should also be possible to set "Allow Forever" as the default.  
(Version 1.2.4)

WJB3WVU  Don't like it myself. Very troublesome at first, allowing everything to connect. Finally decided it wasn't worth the bother, and then trying to trash it requires a little in-depth investigating as to where the actual program resides. Would love to hear from someone who actually found this useful - by that I mean, it actually stopped unauthorized communicaiton.  
(Version 1.2.4)

GLORIOUSJOB  I've been looking for a program like this on the Mac for a while. Being used to blocking programs with my firewall in Windows, it's great to see a company actually allow the same. It works very simply and works well for what it claims to do. The only complaint that I have is that I wish it allowed you to choose the default response (currently defaults to "Until program ends" but I'd prefer it to stay at "Once".)  
(Version 1.2.4)

RICHARD TAYTOR  Little Snitch is certainly useful, but It would be more useful if it supported rules with just-in-time DNS resolution (instead of permanently replacing domain names with IP addresses during rule creation).  
(Version 1.2.4)

TOOL FORCE SOFTWARE  Hello LittleSnitch Developers,

this tool is great. I love it.

It really shows you all. I don't like it if applications phoning home to transfer IPs, Username and all that kind of stuff. The 'Deny' Button is my friend. ;-)

And one hint to all other LittleSnitch users:

Define a new rule for Skype or iChat or disable LittleSnitch when using a chat application.

Try it and you will see what I mean.

Best regards,

Tobias Jordan.  
(Version 1.2.4)

GLOBETROTTERDK  I have just purchased LittleSnitch in an attempt to improve the

security on my G5 running Tiger 10.4.8. I have noticed that It tries

to block apps that want to access the Internet by way of something

called "port 80". Some of the apps that have been caught doing this

are Firefox, WeatherDock and Google Notifier, CopyPaste as well as a process called "SystemUIServer", but on the other hand, LS is configured to allow apps like the QuickTime player to be able to access "port 80". Why the difference between apps, why is it important to block "port 80" and what do you do when a lot of these apps don't allow you to change the port that they are accessing?  
(Version 1.2.4)

HENRIKTEKNIK  This app is awesome!

I wish there was a way to drag & drop apps into the interface, for easier and faster management.

But nevertheless, this app deserves 5 stars!  
(Version 1.2.4)

LEO SPILL  At 40% off - Today is the day to pick up this little gem. Great application, does exactly what it says on the tin. - Seems as if it will still be relevant on 10.5 - but 'who watches the watcher ?' You have to turn a blind eye to the Snitch because the Snitch never rats on itself or it's friends.  
(Version 1.2.4)

MINIMARC  Great program to control your outgoing transfers.  
(Version 1.2.4)

DONMONTALVO  this baby is truly the 'little snitch'. i simply don't feel safe and secure without little snitch installed. before i tried it, i NEVER knew how many things called out to the internet without my being prompted. amazing. this is a keeper...really...

GOOD4U  Am I the only person having problems downloading this version?  
(Version 1.2.4)

SGHUEBNER  My guess is that you have activated the „code injection alert“ in the LittleSnitch-Preferences and that DockFun is trying to change something in the dock that reacts on this switch. You should deactivate the option in LittleSnitch-Prefs.  
(Version 1.2.4)

FANTAMIX  Blocks spywares. controls outgoing to IPs, Ports and servers.

DOM21  Great app! Only one of its kind for the Mac, AFAIK.

CORPSECORPS  _

Haven't noticed the slightest blip with this software since i first started using it when it was fairly new.

(Version 1.2.4b3)

ROADTRIPDK  I am getting a warning from Little Snitch everytime I start DockFun! The error refers to "DockInsteminator", but there are a number of users that have searched for "DockInsteminator" by name and by PID#. The Dock PID# doesn't seem to match the alert.

The number listed (in parenthesis) after "DockInsteminator" also changes if DockFun! has been quit and then restarted during a user login.

At this time, I am still using Little Snitch on a trial basis. It would be nice to get cleared up what is going on here.  
(Version 1.2.3)

SPIROXIS  I uninstalled Little Snitch from my gigabit g4 and now I cant use OSX Tiger's built in firewall. I keep getting a message that I am using another firewall progam and must quit before I can change settings in the Tiger firewall.

I dont have little snitch installed so what is the problem? Help!!!!  
(Version 1.2.3b3)

MICKY1  I've already posted about the "Code Injection Alert"-Problem but now I see that every time I start up an application I need to allow Default Folder X to insert code into it. After every quit it gets killed and when I restart the application I get asked all over again. So the "allow / deny Code Injection" is always only temporary. Apart from that: I'm glad I bought a serial number for this neat application :)  
(Version 1.2.3b3)

BBQ-ALLSTAR  Hrmmm...I d/l the new version 1.2.3b3 and after it installed, it said it had to restart.

Once restarted...all my prev saved preferences from Little Snitch 1.2.2 were gone.

My config.plist was wiped out and updated with a "blank" plist that contained no default preferences -- let alone my 50+ preferences that took months to develop.

I uninstalled 1.2.3b3 and reinstalled 1.2.2 -- and BAM! My preferences were back...I'm staying with 1.2.2!!!  
(Version 1.2.3b3)

MICKY1  The "Code Injection Alert" is a neat idea but I think certain system enhancement applications like StuffIt and Default Folder X should be preset as "OK" in LS 1.2.3. It's just a royal pain in the rectum to have to "allow" these applications at every boot of OSX :)  
(Version 1.2.3b3)

HOLYPOLY  No hangs here on start-up with this new beta.  
(Version 1.2.3b3)

SQUIGLES  Appears to be a conflict with Stuffit Delux :-)

(Version 1.2.3b2)

GUNTIS  After installing the latest update, restarting and logging in, I have blude desktop background for about 2 minutes, then programs, Dock and systme menu starts to load. I uninstalled Little Snitch completely, restarted, installed again, but again the long waiting period after loggin in...  
(Version 1.2.3b2)

MAHER  There is a problem with this release

1. I have a blue screen at end of startup for about 3 to 5 minutes

2. It conflicts with some startup deamons

3. It does'nt let Unsanity Shapeshifter load (probably an APE Conflict)  
(Version 1.2.3b2)

PECOS PETE  The latest version 1.2.3b2 is causing problems for many. Uber slow startup after installation & doesn't allow some other apps & deamons to startup as well. I uninstalled & reverted to previous version ... all is well again.  
(Version 1.2.3b2)

PECOS PETE  A must have for any1 who wants/needs to know which Apps are connecting from your network to the outside world.

Thumbs up !  
(Version 1.2.2)

KIDDAILEY  Used this for many months with the three hour limit before purchasing a license for it. It's been many more months since then and this little app has been worth every penny. It is absolutely stunning how many applications attempt to connect to various services on the net without asking your permission. Thankfully, Little Snitch keeps them all under control in a simple and efficient manner.  
(Version 1.2.2)

MACPETE  On the other hand, it does run with only a 3-hour time limit, and is rad :) I'd rather give you some money, though...  
(Version 1.2.1)

MACPETE  hey, great product! I gotta say, though, and i'm sorry if this seems out of line, but it seems to me this is a little out of the shareware price range. I'd pay $10-15 for sure, though. Hope you decide to change it!

I tried repair permissions, cron-scripts, checked my HD with diskwarrior 3.0.3

and trashed cache-files with Tiger-cache-cleaner, deinstalled and reinstalled it complete about three times but nothing helped.

After I deinstalled LittleSnitch all was back to normal.

ANONYMOUS  Everything still indicates that the LittleSnitchDaemon process is still owned by the user, but attempts to kill or kill -9 fail.

ANONYMOUS  Yeah, but still, for a process to run root, you have to be stupid enough to GIVE it those permissions ;) . It's not gonna get the permissions on it's own....

JON VALENS  Well that's interesting. I was under the impression that you can't catch or ignore a SIGKILL or a SIGSTOP, etc. How do you manage to protect against a SIGKILL from root?

ANONYMOUS  Does not Work on my MacTel (intel) box :(

Blocks, or atleast allows you to block any attempt at an outside connction.

MATT.  Little Snitch does what it says, but it is not only annoying, but its like a throwback to ol' Windows. Sometimes the Application in question is a complicated name that isn't quite specific. Uninstallation is really complicated and I had to use Activity Monitor to force quit Little Snitch and System Preferences, sometimes it crashes and stuff. Don't use this.
