Little Snitch overview

Little Snitch gives you control over your private outgoing data.

Track background activity
As soon as your computer connects to the Internet, applications often have permission to send any information wherever they need to. Little Snitch takes note of this activity and allows you to decide for yourself what happens with this data.

Control your network
Choose to allow or deny connections, or define a rule how to handle similar, future connection attempts. Little Snitch runs inconspicuously in the background and it can even detect network-related activity of viruses, trojans, and other malware.

Version: 5.7.1
v5.7.2 is out: "- Improvements: • Rules for operating system processes in Xcode’s Simulator (iOS, iPadOS, watchOS, …) are now effective for all simulated OS versions and platforms. Note that existing Simulator rules are not automatically converted to the new “catch all” format, so you will get connection alerts for these processes one more time, but from then on they will remain effective also for other Simulator instances. - Bug Fixes: • Fixed: The traffic diagram shown in Network Monitor sometimes stopped auto-scrolling for no obvious reason. • Fixed: The “Mark new rules as unapproved” option in Settings > Advanced was not properly considered for newly added rules in subscribed rule groups. These new rules were always marked as unapproved, even if the settings option was turned off. • Fixed: The inspector pane in the rules window was always opened with its maximum width on macOS Sonoma. • Fixed: The main window of Network Monitor stopped updating after a “Make connections private…” dialog."

@mailtje Single licence upgrade from version 3 to 4 was € 20, in 2019. Now, four years later a new upgrade is necessary, for version 5, of € 39. I'm sorry but I don't understand why it's double the price of last time.

v5.7 is out. Release notes: "• Compatibility with macOS 14 Sonoma. • Fixed a rare problem caused by a bug in macOS Monterey and later when using multiple Spaces, causing the connection alert not to appear on all Spaces. • Fixed a potential crash when clicking a notification from Little Snitch in Notification Center." - - The Spaces bug, created by Apple, is particularly annoying. Hurray that Objective Development found a workaround. (I pestered Apple directly about this one).

5.x has been horrible to use. I constantly run into cache corruption issues where certain sources just completely stop loading. There is a glaring where if you are a developer where Xcode compiled apps will constantly trigger dialogs even if previously allowed all. Just a complete mess. Avoid 5.x.

After upgrading to Big Sur 11.3 last week Little Snitch decided to stop working correctly and it started to block regular apps that I use like App Store, NetNewsWire, and MacUpdater. It didn't affect and browsers such as Brave or Chrome. What it did on a constant basis was block updating apps via the update procedure in the apps. I have tried to delete it via Trash and reboot but some components of the app with not delete and trying to find the uninstaller that is supposed to be someplace in a folder could never be found, rather they suggest you use the option key when opening the app, which still hasn't deleted the files and now have more junk on my SSD.

A top must-have. I've owned a license to Little Snitch for so long I cannot even remember when I first started using it (sometime around when it was first released). Through the years the support has always been excellent as well as the product.

Dated April 22, v4.5.1 may have already been updated on your Mac. - - I have to point out that the recent Little Snitch versions have become more difficult to use from the user's perspective. That dings it one star in my review. However, if we're using Little Snitch in the first place, we've already invited in an amount of user hostility for the sake of having fine grained control over what our computer software is doing out on the InterWebs. Despite the increase in complexity, I've realized that the recent updates/versions provide an even finer grain of control, once you get over the added learning curve. I appreciate that. Now, if only that control was made easier again for the user to access and use via fewer clicks and more obvious options. - - All in all, this is one of my Mac's greatest asset applications.

I give you a nice trick I use (with Little Snitch or other similar app): block http for Mail.app (or other mail client), it will avoid displaying many useless images! (and incidentally save some bandwidth) Usually, the long-standing images of many newsletters are served through http and not https (don't ask me why) , I've just noticed that, and it also applies to many spammers (when they don't use Base64 images). This doesn't apply to serious websites, so it might give you a hint of how a given website is considering privacy... You can also apply more advanced filters on mail clients — I must say that I've always allowed full connections to them and was amazed of the unwanted connections (tracking) they do when I started filtering them. I think we always consider filtering for apps and browsers, not mail clients as they don't have security extensions such as uBlock, uMatrix, etc. What do you think? :-)

Doesn't load system extension properly. Developer is not shown in Security & Privacy Pref Panel under Allow button. Had to disable SIP and re-enable to get extension to load. Until developer fixes this problem, I will continue to give 1 star review.

I have used this app for a while. Then my computer was stolen. Then I found out that I would have to pay $50+ to install it on my new computer. Sorry but as much as I like the app, it's just not worth that much money. Plus, I must confess that it seems that the level of time investment necessary to make it work the way I would like is continuously increasing. There's no convenient way to tell what some of the callouts mean without much research and T&E. I have other things to do; I'm an engineer for christsake...LOL. If LS actually helped solve that problem and I do believe it can then it would be worth more to me but the current look up info is not very useful because it frequently finds nothing...
