Little Snitch 6.3 nightly (7163)

New Features and Improvements

  • Runs on macOS 26 Tahoe.
  • New “Focus on” context menu option in Network Monitor to show only connections for the selected app, process, domain or country.
  • Added quick filters for active and inactive rules in the rule list.
  • Added a description of the currently selected quick filter to the subtitle of the top bar of the rule list.
  • Showing the total count of rules matching the current search in the top bar of the rule list.
  • The inspector now shows app bundle paths instead of the executable path for rules and connections.
  • Showing an Internet Access Policy for Safari web apps added to the Dock.
  • Added a setting in Settings > Security to instruct Little Snitch to skip server name verification. This results in fewer connection alerts showing only an IP address, but makes it possible for processes to fake server names.
  • When a process has declared a custom name that’s different from it’s actual name on disk, this name is now also shown in the details section of the connection alert.
  • Improved responsiveness when allowing or denying connections via Network Monitor.

Bug Fixes

  • Fixed a bug where the Networks sidebar did not update after changing profile details.
  • Fixed a bug where the “Automatic Profile Switching” settings pane did not update after changing profile details.
