Little Snitch for Mac

02 April 2021

Alerts you about outgoing network connections.

What is Little Snitch for Mac

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.

What's new in Little Snitch

Version 5.1.2:
New features:
  • Capturing traffic of individual processes in PCAP format. This feature is available from the command line via littlesnitch capture-traffic.
  • The rules shown in the configuration application can now be sorted by the remote server’s domain name. Clicking the table header in the rules window brings up a menu with available sort options.
Bug fixes:
  • Fixed automatic update of “My Location” in Network Monitor.
  • Fixed a bug where a profile selection button appeared in the connection alert even if no profiles were available.
  • Fixed a rare crash of Little Snitch Agent during upgrade. This fix affects the next upgrade, the crash can still occur when upgrading to this nightly build.
  • Fixed a bug in detecting the path of Java applications.
  • Fixed a possible crash of Network Monitor.

v4.6 is out, running ONLY on macOS 10.15 Catalina. It's the last of the v4.x series. v4.5.2 is the last version for macOS 10.14 Mojave and contains an important security patch.

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.

It's simply the best! Never have had big problems with it and it rescues me often in the past. A big thanks to the developers...

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...
