I recently installed Little Snitch with homebrew to try it out. I’m annoyed now by it bugging me about Demo mode all the time and not making it easy to quit (it auto restarts if killed via htop).
So I’ve tried to uninstall it with brew uninstall little-snitch. But that failed with some permission errors:
$ brew uninstall little-snitch
==> Uninstalling Cask little-snitch
==> Backing App 'Little Snitch.app' up to '/opt/homebrew/Caskroom/little-snitch/
==> Removing App '/Applications/Little Snitch.app'

Now if I rerun the uninstall I get the following:
$ brew uninstall little-snitch
==> Uninstalling Cask little-snitch
Error: It seems there is already an App at '/opt/homebrew/Caskroom/little-snitch/6.1.1/Little Snitch.app'.
Also the daemon is still running, so the uninstall seems to have completely failed:
What shall I do now? I couldn’t find an “Uninstall” button in the Little Snitch UI so I’m stuck.
This question is related but doesn’t involve brew: Little Snitch uninstalled properly but Little Snitch Helper still here
