How to uninstall Little Snitch Mini on Mac

Little Snitch Mini is Objective Development's network monitor from the Mac App Store, and it carries a network system extension inside the app. Objective Development's instruction is to remove it by moving the app to the Trash in Finder, because other removal methods, third-party removal tools included, do not uninstall the system extension. So do the app step in Finder yourself, then use Mole for what is left. The paid Little Snitch is a different product with its own uninstaller and is not covered here.

Remove the app in Finder

Quit Little Snitch Mini, open Applications in Finder and move Little Snitch Mini to the Trash. macOS tells you that this also removes the contained system extension. Objective Development: uninstalling Little Snitch Mini

Where the data lives

Location What it holds What Mole does
~/Library/Containers/at.obdev.littlesnitchmini The app's sandboxed data and settings Listed and selected by default
~/Library/Application Scripts/at.obdev.littlesnitchmini Sandbox scripts folder Listed and selected by default
The app's temporary folder under /private/var/folders Temporary cache Listed and selected by default
~/Library/Group Containers/MLZF7K7B5R.group.at.obdev.littlesnitchmini, ~/Library/Application Scripts/MLZF7K7B5R.group.at.obdev.littlesnitchmini The App Group the app shares with its system extension Not listed

Mole never lists an App Group that a system extension claims, because an activated extension can outlive its app.

Check the result

pgrep -il "Little Snitch"
systemextensionsctl list | grep -i littlesnitch
ls -d "$HOME/Library/Containers/at.obdev.littlesnitchmini" "$HOME/Library/Group Containers/MLZF7K7B5R.group.at.obdev.littlesnitchmini"

No output from pgrep means Little Snitch Mini is not running. A line mentioning at.obdev.littlesnitchmini.networkextension from systemextensionsctl list means the extension is still registered; no output means it is not. ls -d prints each folder that still exists and reports "No such file or directory" for the rest; the Group Containers folder is expected to remain after a Mole uninstall.

Also look in System Settings › General › Login Items & Extensions for a leftover "Little Snitch Mini Helper"; it is the app's own login helper and was gone after the test uninstall.

What Mole lists

  • The container, the Application Scripts folder and the temporary folder under at.obdev.littlesnitchmini are listed and selected by default.
  • The MLZF7K7B5R.group.at.obdev.littlesnitchmini App Group, in Group Containers and in Application Scripts, is not listed, because the system extension claims it.
  • When an activated Little Snitch Mini extension is present in /Library/SystemExtensions, Mole shows a System Extension notice before the uninstall; it does not deactivate the extension itself.
  • There is no Homebrew cask for Little Snitch Mini.

What this test covered

On September 21, 2026, Little Snitch Mini 1.9 from the Mac App Store was uninstalled with a Preview build of Mole 1.15 (build 282) without ever being opened, so the network extension was never activated: the app (20 MB), its Application Scripts folder and its 4 KB container went to the Trash, and its embedded login item was pruned. On September 26, 2026 it was reinstalled from the App Store, opened once (the record does not show the extension being activated), and uninstalled with a development build of Mole with every listed row ticked. The app, the Application Scripts folder, the container and the temporary folder went to the Trash, and the App Group folders in Group Containers and Application Scripts stayed. Removal with the extension activated, and the Finder route, were not tested.
