Editors' Review

Despite fewer malware threats to Mac systems, there is still a need for data protection. With Little Snitch for Mac, users can prevent personal information from being sent out, although its limited features may not be worth the program's price.

Little Snitch for Mac can be tried out for free for 30 days. After that, $29.95 buys the full version with no restrictions. While it does include a native installer, loading the program proved tricky and required a restart in order for it to work. An extensive and complicated end-user agreement also needed to be accepted. Technical support and updates exist, but the program contained no visible instructions on how to use it. While advanced users would not likely have a problem with this, the potentially complicated permissions needed to tailor the program would be too much for beginners. In terms of function, the program requires little interaction and runs in the background. After setting up defaults, it monitors the user's system for programs that attempt to send data out. This could not be evaluated since we didn't have any applications that tried to do this, although the program indicated it was up and running. While this sounds similar to a firewall, the program claims only to be a privacy application rather than a full security program.

While functional and easy to use for those with security knowledge, Little Snitch for Mac's price may not be worth the limited functioning, and those looking for security may be better off looking elsewhere.

Editors' note: This is a review of the trial version of Little Snitch for Mac 3.0.3.

Full Specifications

What's new in version 4.3.2

Improvements

  • Improved performance of Little Snitch Configuration when "combine rules" is enabled.
  • Added support for Touch ID to enable/disable rule and profile editing when clicking the lock button in Little Snitch Configuration's toolbar.
  • Process paths are now treated as being case-sensitive, even on case-insensitive file systems. This resolves an issue where rules created manually using Little Snitch Configuration would not match if the entered path didn't match the actual path exactly. Such rules are now also marked as invalid and can be found in the "Invalid Rules" filter in the left sidebar.
  • Code modification alerts can now be minimized, just like regular connection alerts.
  • Improved detection of processes whose code signature got invalid because the corresponding code signing certificate was revoked.
  • Improved layout of rule group subscription editor.
  • Added sharing options for rule group subscriptions. In the left sidebar, Control-click a rule group and select "Share", or use the share button in the rule group subscription editor to share the rule group with others.
  • Added support for WireGuard VPN.
  • Added a factory rule for connections from syspolicyd to api.apple-cloudkit.com.
  • Rules whose process paths contain symbolic links are now marked as invalid because they can never match.
  • Various improvements to Subscribed Rules Inspector.

Bug Fixes

  • Fixed an issue where Little Snitch could break DNS lookups for all programs. This bug first occurred in version 4.3.
  • Fixed an issue causing the connection alert to create a rule only for the app itself, ignoring the via-process, if the via-process was a Java process.
  • Fixed an issue with ask-rules causing the connection alert to create rules that were less specific than the ask-rule that caused the alert to be shown in the first place, leading to repeated alerts.
  • Fixed an issue causing Little Snitch to deactivate Silent Mode and switch to Alert Mode unintentionally.
  • Fixed an issue in Little Snitch Configuration where dragging of rules didn't work correctly when "combine rules" was enabled.
  • Fixed an issue in Network Monitor where traffic captures were incomplete.
  • Fixed a few issues with the network traffic meters in the menu bar.
  • Fixed an issue causing the buttons for toggling the map and the inspector in Network Monitor to be not clickable under certain circumstances.
  • Fixed an issue causing traffic captures not being stopped when Network Monitor was disabled in preferences while traffic was being captured.
  • Fixed a possible crash on OS X 10.11.

Other

  • Numerous user interface fixes and improvements.
