ENCRO  Please see my extensive comments on http://www.macupdate.com/trimmit as these dangers apply equally as well to Xslimmer.

Use an application such as http://www.macupdate.com/codesign-checker to test if the application is signed before making changes.

These apps can cause major problems for code signed applications that access the keychain and it is in your best interest to avoid using them to modify code signed binaries.

Unsigned binaries are fine to experiment with for size reduction etc.  
(Version 1.7.5)

EXEGETEJR  I received Xslimmer as part of a MacUpdate Bundle purchase and continue to be very pleased with both the software and the developer's commitment to the product and support. For me Xslimmer has worked nearly flawlessly. The only issue I had was quite minor in regards to having Xslimmer save backups to a folder, which the developer was quick to respond and helpful. I give the product a 4.5 for clear and easy to use interface, good stable operation, effectiveness and developer commitment to the software and support. Xslimmer does what it says and does it well!  
(Version 1.7.5)

WEBMOTIVA.COM  Apple should incorporate it into Snow Leopard. 1 to 6 GB is a great HD space difference.  
(Version 1.7.4)

WALRUSCP  This app has a great developer behind it. I was the one (or one of the ones) who discovered the blacklist bug fixed in 1.7.2, and throughout the process the developer was pleasant and responsive.

As for Xslimmer itself, it has claimed untold MBs on my MacBook's hard disk, working as advertised. Occasionally you run across an application that gets screwy after slimming, but that's what the back-up and restore options are for. Most apps that will be troublesome when slimmed are on the blacklist.

Overall, this is a very easy to use app that is a must-have for mac owners who need to squeeze as much memory as possible out of their hard drive. Highly recommend it!  
(Version 1.7.2)

JFFS  If you are using Snow Leopard don't be too hasty slimming. Removing PPC code is fine, but there are times that you will need the 32-bit Intel code if plugins don't work in 64-bit. Examples: Safari and Safari Adblock or Quicktime X and the AC3 codec/Perian.

It would be nice to be able to just strip out the PPC code in the latest version until more third-party software has been updated to work in 64-bit.  
(Version 1.7)

ROD76  This app was just sitting unused in my Utilities folder until I bought an SSD. What a difference it has made since. Xslimmer has given me back valuable disk space and now I can't do without it.

The exclude an application ability is what sets this app apart from its competitors. Every once in awhile I'll find an app that just doesn't like having its data slimmed and after a quick restore from back up I add it to the exclude list and it never gets slimmed again. Its a real sanity saver compared to the alternative slimming applications.

The only complaint I have is that System Profiler displays some apps as universal or leaves the field completely blank that are in fact intel only. Viewing "Get Info" directly from the application itself reveals the correct information and no amount of refreshing System Profiler rectifies this.

The afore mentioned quibble has no actual effect on application performance or the system itself (my MacBook Pro is just about trouble free). It's just a minor annoyance for someone viewing the application section in System Profiler and knows the information displayed there is wrong.  
(Version 1.6.5)

GARY30  I have used this application for over two years and never had a problem. Nevertheless, it would be foolhardy to use a produce like this without taking some elementary precautions. Xslimmer gives the option to back up the files it slims and produces a log. So if i ever have a problem I am confident I could restore the files with no problem. I also have Time machine and Super Duper.

One thing that surprises me with 1.6.3 is that the Adobe CS4 applications are NOT blacklisted. Adobe has always been a problem and its bloatware is something i would definitely like to slim. For now, I have subtracted them from the Xslimmer list on my own machine. If anyone has had success slimming CS4 applications that information would be most welcome.  
(Version 1.6.3)

RICOBLUES  Great software. I run it on all application of my MacBookPro. No problems and fast loading of apps. I'm very satisfied.

Have a nice day, Riccardo.  
(Version 1.6.3)

CASTLE  I ran Xslimmer on all the apps in my app folder that weren't blacklisted. I'd say about half now won't launch and are having to be re-downloaded. Examples include LiquidCD, MacPAR Deluxe and Wallet.  
(Version 1.6.2)

PINNOCHIO  I tried DEMO - to SLEM "TecTool Pro4" and got the message- REQUIRED ADMIN PRIVILEGES WERE NOT GRANTED. The same with "Google earth". Need help.  
(Version 1.6.2)

SIMONM  Some of the gains are amazing, especially on the Apple apps. Mail from 289 to 40 Mb, iChat, 115 to 17.4, iCal, 94 to 16 etc etc! The interface could use a little improvement, like being able to sort the list of apps prior to slimming based on potential saving and being able to export slimming log, but the guts of the program run fine! Saved over 4 Gb on my nearly full laptop drive.  
(Version 1.6.2)

GARY30  I have been using this program for almost two years and had only one problem. I just replaced the slimmed file with a backup which was generated by the program. As with any software that utility that you know is going to poke through your files, you will want to make sure you have a current backup before running. You can use a program such as "Easyfind" to see if (or where) there are leftover "lproj" resources. You can also use a number of programs that are indiscriminate to varying degrees to remove all such files from all packages (except a language you want to keep). I think Xslimmer is a reasonably safe and convenient option.  
(Version 1.6.2)

DANA SUTTON  I wouldn't touch a program like this. Mucking around with programs' code sounds like a great way of inviting trouble. And what's the benefit of shrinking programs' sizes in a day and age when disk space is so cheap and plentiful?  
(Version 1.6.1)

PMASON  Now Xslimmer has really done it.

On a 2.4 Ghz Intel Core 2 Duo machine, the application wrongly figured it was running on a Power PC processor and proceeded to merrily remove the wrong code from hundreds of applications.

I sent the developer a screenshot showing the "About this Macintosh" Finder window and the About window from Xslimmer, side by side. The Finder reports "2.4 Ghz Intel Core 2 Duo", Xslimmer says "Running on PPC".

These crippled applications will have to be reinstalled.

These results are forcing me to conclude that Xslimmer is dangerous. Earlier this month the developer offered my money back. I said never mind. But as I wrote to him a few minutes ago, now I'm taking their offer.

PMASON  Further to yesterday's comment, a check of applications that had unwanted language packs removed by Xslimmer shows that, in fact, these were removed from the first level only.

While a Get Info on the application will show that only the desired language(s) remain(s), in fact hundreds of unwanted language packs still reside inside these applications, only at deeper levels. These will not show in a Get Info window. As such, you will not notice unless you check the application package contents, either manually or with a file finder utility.

It therefore appears that Xslimmer doesn't work recursively, which means that the point of removing unnecessary material is being achieved only partially.  
(Version 1.5.3)

PMASON  Trouble in paradise.

Running a fresh Leopard install on a PPC machine, Xslimmer 1.5.3 has just stripped Spanish language packages from some applications, although Spanish is selected as one of my two language preferences (after English) in the International panel of System Preferences.

Most strange of all, I'm now finding that random components in the (expressly excluded) System and Library folders have also been stripped of Spanish language packages. I have two internal discs with identical Leopard installations, so comparison is easy and definitive.

The more I compare, the more components with missing Spanish language packages I'm finding. Where this has happened, the component has been left with only an English language package, whereas the identical component on the other internal disc has both English and Spanish language packages.

I normally run in English, so this is not an immediate disaster. But it does mean that my computer can no longer startup in Spanish. Given the circumstances, I won't even try.

Getting my machine back to pre-Xslimmer state will require a complete reinstallation. I'm not amused.  
(Version 1.5.3)

DNEM41  This is a wonderful application that will pay for itself with just a few uses. Google Earth was reduced from 111 MB down to 61. Firefox went from 46 MB down to 28. MacJournal 32 to 20.

The amount of space being saved is arguably negligible considering my 320 GB hard drive plus 160 external HD. But it is how much faster these apps are after getting rid of the universal binaries and other language packs. I love the change log which keeps track of all apps that you have been "slimmed" which allows me to 'remember' the numbers I just spit at you above.

A first time user of course should be scared about slimming an application useless, so I started with free or open source apps (like Firefox, Google Earth, LiveQuartz, etc...) that you can easily re-download if something happens. But before that could even happen, Xslim provides a user-generated "blacklist" of apps known to have issues after being "slimmed". And of course you choose how frequently you want that list updated.

If you come across an app that wasn't on the blacklist, you can report it for future users. And hopefully you have backups on, so you can easily refer to them and have the whole app back again.

Very useful and smart application. I would give it 10 stars if I could. Anyone agree?

Thanks developers!  
(Version 1.5.3)

JONO  After installing version 1.5.3 and running it, Terminal will start but not respond...  
(Version 1.5.3)

MAZZBOY  I would like to give this 5 stars for everything, because it really has cleared up a lot of space on my hard drive, which I'm very pleased about. However, I've noticed programs crashing a lot now, when before they didn't.  
(Version 1.5.2)

CALL ME YO DADDY  A great little app simply gets better with this new update. Now I can slim down Safari and other apps that are far too big due to language files that before were on the black list of apps that could not be slimmed in previous versions of Xslimmer.

This app has saved me several gigabytes of disk space and apps tend to load faster since only one language file needs to be loaded, English!   
(Version 1.5.2)

YULETIDE  Great little app, and the price is right! Works as advertised... the self-updating blacklist and the "genie" which searches for updated applications (which then need to be re-slimmed) are also great!  
(Version 1.5.1)

LARAINE  I thought I would try this software after reading the reviews for it. Hardly anyone had a bad word to say for it! It wasn't so much what the software is intended for (saving HD space) that attracted me as the comments on how much snappier it made applications feel. It is also reasonably priced in comparison with other software that does only one thing. Many cost as much as $20, some even more. I was very happy to pay $12 for this, especially if it helps the developer make the software even better. It's certainly very nice to use. I shaved about 1.5 GB off the contents of my 320 GB hard drive. While that might seem relatively small on a drive this size, I'm expecting the benefits to show when I back up because my back-up drive is only 80 GB.   
(Version 1.5.1)

PERSON1229  Xslimmer is amazing. The constantly updated blacklist of applications that blow up if slimmed adds so much to the value of Xslimmer. I wouldn't trust anything else to slim my computer.

87% of statistics are made up, so I don't trust anyone who's said "x% speed increase!" but I do know that Xslimmer has saved me many gigabytes which is essential on my iBook's 60GB hard drive.  
(Version 1.5.1)

MAC ADAM  MonoLingual do same… and free ( but not nice as )  
(Version 1.5)

RENESIS  I found out about Application slimming apps, after users were complaining about disk space on the MBA. So I googled the recommended Xslimmer, and users were also reporting that their applications were opening up faster, so I had to give it a try. I am glad I did, it has a nice UI, lots of options, some apps got a speed boost, and it lets you know what apps are blacklisted. Overall I give it 5 stars.  
(Version 1.5)

IMPISH500  Just ran the update version of Xslimmer, it keeps getting better and better with every update. Apps launch much faster (even Turbo CAD v. 3 for the Mac). My hats off to the developer...  
(Version 1.5)

CMFOLEY  Just ran the app and my macbook is much snappier.

Great interface and no issues so far. As a power user the benefits justify the expense and I am happy to support the Mac shareware community when they create exceptional software.  
(Version 1.2.8)

HATEMAIL  Had a problem with the demo (which disappeared on it's own), and the developers were extremely helpful.

I bought the software and so far it's pretty much done what it says. A couple things could maybe be streamlined, but it's a solid app.   
(Version 1.2.8)

YESUAINI99  Hardware: MBP 2.4G, 15", 3G Ram, 160GB HD

Bought Xslimmer in the MU bundle just a few hours ago.

Ran it but crashed when the Marine Aquarium screen saver (bought at the same time) engaged after i walked away and my MBP became idle.

So I ran slimmer again but saw many apps already got backed up (even though not showing in the Xslimmer history) in the User folder.

So now, the second time, I deactivated the screen saver and it ran successfully, except I noticed I am now short almost 5GB of space than before I used Xslimmer. (it didn't get slimmer, it got fatter.)

I know I can remove the backed up apps in the User folder, but since it crashed the first time, I now have many duplicate app files in the user folder ([App_name] and App_name-1 duplicates). I don't know which one I can remove to keep the very original app safe.

I did notice some apps started faster (such as Google Earth).

Maybe they can have built-in disable screen saver so it doesn't crash like it happened to me.

I am waiting for Xslimmer to contact me and let me know what to do with the 5GB of Apps + App duplicates...

(Version 1.2.8)

BRETTD  To the author: Monolingual 1.3.5 (released a year ago, long since superceded) fixed the Rosetta problem. It also detects the current architecture by de-selecting it. Same thing it does for in-use languages. Monolingual also has version checking built-in.

I don't know if you're ignorant of Monolingual's features (you should know of what you speak), or feigning it to have an excuse for frightening people into using your product. Either way, MU users deserve to know there's a no-cost, open-source alternative.

With the most expensive laptop drives running about 60 cents per GB and desktop drives about 20 cents per GB, the wisdom of stripping architectures to save a few GB is pretty foolish.

If users don't understand how to use either tool, they have no business stripping architectures and languages from their system *anyway*.  
(Version 1.2.8)

LATENITESOFT - PEDRO  @Brettd

I don't like to comment on other developers' work, but I believe that Xslimmer and Monolingual are quite different. Monolingual could have a greater appeal for some users, and while that's of course perfectly fine, it doesn't mean it's a better (or a worse) product.

Xslimmer will allow you to select which applications you want to slim, and will not deal with system libraries, frameworks or components. According to Monolingual's comments thread here in MacUpdate, Monolingual is essentially a batch tool and you have to be careful not to remove essential files in your system (Rosetta can be destroyed, for example, making it impossible to run PowerPC applications).

Monolingual requires the user to select from a list what architectures should be preserved, while Xslimmer automatically uses the best one for the machine it is running on. Some users may find Monolingual's architecture list (which includes more than a dozen entries) informative, but we believe others might think it's too much detail. We consciously chose not to force the user to understand the implications of selecting which architectures to preserve.

Xslimmer employs a dynamic downloadable blacklist of troublesome applications, instead of the static one used by Monolingual. Xslimmer is also able to backup your apps before slimming.

Xslimmer is being actively developed and maintained. It supports Panther (like Monolingual), Tiger and Leopard - new code-signed binaries, for example, are handled correctly by the latest version of Xslimmer. Our blacklist is updated constantly using the feedback we get from our users.

I think Xslimmer offers a lot of value for users looking for a pleasing, reliable and user-friendly way to save some space. It is easier to use, more informative and clearer. It is also smart enough to detect the architecture it is running on and act accordingly. It provides you with detailed information about what applications can be slimmed, how much space will you save, or if an application is known to cause problems after being slimmed down.

Monolingual may be all you need, and that's great. We have made a huge effort to create interesting and compelling features, and we are extremely grateful to the many users that have come to appreciate Xslimmer's added value.  
(Version 1.2.8)

BRETTD  Why waste $12 when Monolingual (and other free programs) do exactly the same thing..for free? Monolingual even offers exacting control over which architectures you remove.  
(Version 1.2.8)

THIRROUARD  Wonderful software!

It does the job nicely, it look sweet ^_^, it does a backup of your application, just in case it would screw anything, etc.

The only bad thing is that the process is a little slow, but considering the job done, I don't think it's an optimisation issue... just big job ^_^... the first time ;) A chance we don't have do to it all the time...

I was very tight in my 150Go, so this gave me a lot of help... more than 1Go, considering I already removed most languages with monolingual before ;)

I've read that the new version of monolingual can remove the PPC/Intel code from an app too, but didn't try, Monolingual is more cold and not as coutious as this software ;)  
(Version 1.2.5)

C.HILDING  While this is "just" a front-end for the command-line utility "lipo"* it does it with the ease and style that we're accustomed to on the Mac platform; and even if you ARE the kind of masochist user who wouldn't mind using "lipo" on your own you'll still benefit greatly from Xslimmer's blacklist feature, which prevents slimming applications that would cease to work afterwards.

At $11.95 you can't go wrong; I give this program 5 out of 5, it's essential on any Mac!

* See, Apple has humor, "fat binaries", "lipo", get it? :-)

Other essential applications in the system cleaning category:

* Monolingual (free), removes language packs that you don't need.

* CleanApp ($10), my uninstaller of choice, it monitors file system actions taken by all installed programs so that when you're ready to delete them it finds every file the program has ever used. It is MUCH more thorough than the previous king, AppZapper (which is now behind times).

* Disk Inventory X (free), scans through your selected hard drives/folders and gives you a breakdown of what is actually stealing all that disk space; I've reclaimed tens of gigabytes with this program by finding large, old files that I didn't know I still had hidden around the disk.  
(Version 1.2.5)

GAOSHAN  This is a very nice app. Great way to squeeze space out of the ever shrinking available pool. However, if you are a command line kinda person you might like to know about the command line program lipo which will also "slim" universal binary files and is built into your Mac.

Check the man file for how to use it (and if you don't know how to do that you should stick to using Xslimmer... trust me). It isn't nearly as convenient and informative as Xslimmer but for us do-it-yourself types it's the only way to roll.  
(Version 1.2.5)

LATENITESOFT - PEDRO  We could finally solve PROGRAMHAPPY's issue when he contacted us from a different email account. I thought this was worth mentioning, because unfortunately this is not the first time we've had a hard time trying to get our emails through.

- Our licenses are processed and sent automatically, so they should reach you minutes after your purchase.

- If you don't receive your license soon, you can try to use the form at http://www.xslimmer.com/Registration/LostLicense/ and enter the email address associated to your PayPal account.

- If that does not work either, please email us providing an alternative email account whenever possible. Include also your original address or your transaction ID, so that we can identify you.

Our business relies on customer satisfaction and word of mouth, so we try to answer all the emails sent to us. When we notice that our messages are not reaching their destination, we try several options: we resend from different accounts; we remove or zip attachments; sometimes we even had to open a direct telnet connection to the destination mail server to see what's going on.

So, if you don't receive what you expect, please try to provide a different account where we can try to reach you.

Thanks!  
(Version 1.2.4)

PROGRAMHAPPY  I paid on August 8, via my PayPal balance, so I was supposed to receive my license "immediately." (That is precisely WHY I used my PayPal balance.) Well, it's three days later, and I have received neither my product nor any contact whatsoever from the developer (despite using the developer's contact form, as requested on his FAQ page)! And no, my SPAM filter is not involved. I have a custom email server that purposely has no SPAM filter. Plus, all email sent to that email address gets cc'd to both a Gmail account and a Hotmail account. The license email is not in any of those THREE email accounts, which is irrefutable proof that the developer never emailed my license. I will wait 48 hours before taking further action.  
(Version 1.2.4)

LATENITESOFT - PEDRO  Hello,

Thanks everybody for your positive reviews, we are proud you find Xslimmer useful!

@Bob - Among other safety measures, Xslimmer has a downloadable blacklist with some applications that do not work properly after being slimmed down due to integrity checks that they perform on themselves. Skype has been there for several weeks, so Xslimmer should have warned you. Could you please contact us at support@xslimmer.com so that we can analyze your case in depth?

Also, the "detailed information" drawer will display any side-effects that may happen with certain apps, such as the need to reauthorize them to grant them access to the keychain again (this happens because Keychain will detect that the application has been modified).

Finally, Xslimmer sports a backup feature, so if everything else fails, you can use that to restore your original app instead of having to install it anew.

Thanks again for your comments!  
(Version 1.2.4)

RON BELL  This software saved nearly four gigabytes of space on my PowerBook G4 and has performed flawlessly every time I have updated it. Slimmed applications work well, take up less space, and seem snappier and more responsive. Recommended.  
(Version 1.2.4)

BEN_MARKO  Trim the Fat is free. If this was a bit cheaper the price still wouldn't be justified as it still doesn't give warnings to many apps before slimming when it should. I used it on skype and skype has to be reinstalled afterwards.  
(Version 1.2.4)

O5220803  An excellent application! It's well designed and easy to use. I estimate I gained a 10% speed increase in both FX and TB with XS! Besides, I gained combined total of approximately 40MEGS by eliminating PPC code in FX and TB with XS. XS is well worth its nominal shareware fee. It represents an excellent value! Worth every star I give it!  
(Version 1.2.4)

CELESTIALWARRIOR  This is by far one of my most valuable applications. In total, I've saved at least 3 gigabytes with Xslimmer.

Every time I install or update an app, more space is wasted on my machine. This app gives me that space back. I have never made a better purchase in my life.  
(Version 1.2.2)

PHILIPP.GERARD  Perfect tool with a lot of patches that introduce new features etc. - very well :)

STANLEY JR  5 Stars  
(Version 1.2.2)

STANLEY JR  genial, great program !!!! Thanks  
(Version 1.2.2)

MOCHANT  I consider this to be a must-have utility on all of the Macs I manage. I have a lot of applications on my systems and I've saved as much as 6GB with the new ability to trim unneeded localization code. The blacklist and backup features are well worth the nominal investment for such a nicely designed utility.  
(Version 1.2)

NORAA  Excellent product, truly wonderful. I saved nearly 2gb of data - rather impressive. The blacklist is a wonderful function, and am really glad it is there - as there were a few applications I have that are on it. Finally, it Xslimmer can even trim itself! How cool is that :)  
(Version 1.2.0)

MEATMCGUFFIN  This needs a MUCH tighter check on whether a language can be deleted or not. I have my default system language as UK English and xslimmer will allow me to delete all language packs that are not UK English, which includes regular English.

If I had hit slim when i first scanned, instead of looking at xslimmer's preferences, my system would be useless now. To test this i used xslimmer itself and it stripped *every* language leaving it useless and unlaunchable.

You really should disallow slimming on apps that only have one language remaining.  
(Version 1.2.0)

PHERES  I used to use Trim the Fat, which is very nice. However, this application definitely has the nice features to justify the nominal price.

I also love the developers - they are extremely responsive to both feedback and bug fixes.

Gets a 5 stars for me.

Perfectly designed.

I once “slimmed” my Intel Mac and tossed what was referred to as “PPC Architecture” That was an error, hosing my system.  
(Version 1.1.5)

DAMINO  Excellent : efficient, nice design, easy to use.  
(Version 1.1.3)

HANDYMAC  As noted, there are no-cost ways to do this, and the authors of TrimTheFat and Monlingual are to be praised for their services to the Mac community. However, XSlimmer does it more elegantly, and safely (the Blacklist -- which prevents slimming apps which might no run if altered -- is an inspired feature), and is an excellent example of well-crafted Macintosh software. I look forward to seeing what these folks will come up with next.

The new version works fine on my iBook with 10.3.9; thanks, guys.

(Version 1.1.3)

FAHLMAN  While you can do this for free as you suggest, for less than $10, XSlimmer saves a back-up of the slimmed application so that you can verify taht it runs properly after slimming and is easy to restore if it doesn't. It also contains a blacklist of applications that don't operate properly, for one reason or another, after slimming that it will not slim. Not to mention it'll slim a whole folder of application a lot faster than manually clicking on each application one at a time. I think the guys are offering a discount of $3 if you buy before 12/10/06.  
(Version 1.1.3)

MARIUS_TH  There are a bunch of 'free' ways to do this (personally i've set up a right-click command trough OMCEdit),

though I bet non look as nice as Xslimmer  
(Version 1.1.2)

CED@TOKYO  I tried this one on my macbook, and it worked perfectly. After slimming 50 Meg with the trial version, I decided to buy it. I almost saved 400 Meg of unncecessary PPC stuff... No problem with applications after slimming. Great soft !!  
(Version 1.1.2)

ENDUSER  I just love simple and elegant mac apps. This one does exactly what it promises. And although the job it's doing is rather technical - the user interface makes working with Xslimmer a real pleasure.

Thanks for the update. Makes a great app even better!

CAKEY  Very nice little program. Seems to work well and does same some resources.  
(Version 1.1.1)

JORGE-XSLIMMER  Xslimmer 1.1.1 solves the /Applications/AppleScript folder bug, introduced recently and discovered after launch of Xslimmer 1.1 that caused Xslimmer to crash.

The new version is already available for download. (11/19/2006, Version: 1.1.1)   
(Version 1.1.1)

HAUSLENDALE  If you include "/Applications/AppleScript/" folder the application will crash. This has been tested on both Intel and PPC.

Xslimmer is a must have! It not only cuts the size of most programs in half but I swear progs the like FireFox load much faster and also seem to run faster. Don't have any figures just a feeling.  
(Version 1.0.8rc2)

FROMAGE-HEAD  Paying for that kind of app? I've got a doubt.

And often you don't gain so much space. If you really want to save space, remove language packs.

It is true that there are other apps that can help you achieve similar results, but not in such a nice and friendly way.

I like this app a lot, thumbs up.  
(Version 1.0b)

JORGE-XSLIMMER  Activity Monitor has been added to the list of protected apps. Thanks for pointing out.  
(Version 1.0b)

FAHLMAN  While Monolingual has the capabilities to do the same thing the GUI is not as nice, it does not show the progress of each individual file, or does it show how much was saved from each file, just the total saved. This looks like a nice product. Will people pay $10, I don't know, but the developer is welcome to charge whatever price he feels is fair for his time. If people pay, good for him.  
(Version 1.0b)

JORGE-XSLIMMER  First of all, thanks for your comments.

We have now added a beta license for download so the application can be really tested. It was intended to be there in the first place.

On the Activity Monitor issue, we are investigating. I will provide you with feedback as soon as we are able to determine the cause of the problem.

On the temperature issue, could you please provide us with a little bit more info? Which application where you slimming at that point?

Thanks again.

ANKLEDEEPCLAMS  Monolingual, at http://www.macupdate.com/info.php/id/7758 , does this and more. And it's free. I'm not impressed.

GAZMAN  First, the developers website states that Xslimmer is a "Public Beta", its not, its a beta demo, it is limited to 50MB unless you register.

Second, halfway through the slimming process my fans started roaring and iStat Pro informed me that Xslimmer was using between 98 and 99.8% of the CPU and the temperature of my CPU leapt from a comfortable 46°C to a raging 72°C.

Third, the program then became unresponsive and had to be force quite.

Fourth, after this I decided to check things out with Activity Monitor. Activity Monitor failed to launch. No worries, following the developers instructions I had told Xslimmer to make a backup of all altered applications. However, when I replaced the now slimmed Activity Monitor with Xslimmer's backup copy of AM, it still failed to launch.

Very unimpressive. Obviously still at an early beta stage, but they want you to fork out $10 for the privilege of helping them iron out some pretty heavy bugs.

I'll be staying well clear of this app from now on.
