Removing Little Snitch completely (Mac OS X Snow Leopard)

Question

I uninstalled Little Snitch months ago. Or so, I thought.

When opening Console.app, I see something like this:

Here’s a textual log:

Spotlight searches for ‘little snitch’ or ‘littlesnitch’ yield no results. Yet, it seems like I didn’t get rid of Little Snitch entirely, since it’s still using up my CPU.

Any ideas?

Answer 1

Have you tried downloading Little Snitch again and running the Uninstaller?

Little Snitch 2.2

Answer 2

Have a look in the following locations for plist files that look like they are related to Little Snitch. They will most likely start with at.obdev :

/Library/LaunchAgents
/Library/LaunchDaemons
/System/Library/LaunchAgents
/System/Library/LaunchDaemons
~/Library/LaunchAgents
~/Library/LaunchDaemons

Move the offending files to a different location, reboot and see if it fixed things.

Be very careful, especially with the /System locations, because if you remove the wrong file, it could harm your system.

Answer 3

You need open terminal:

cd /private/var/db/launchd.db/com.apple.launchd

make a backup copy of overrides.plist (make sure it is there using the ls command)

sudo cp overrides.plist overrides.bak

open overrides.plist

sudo vim overrides.plist

Look for any Little Snitch UIAgent entries and remove them. Save. Close. Reboot. (this should also remedy the peruser entries too)

Check Console if there are any entries.

Answer 4

There's no need to edit any files; just unload the service and delete its plist:

sudo launchctl unload /Library/LaunchDaemons/at.obdev.littlesnitchd.plist
sudo rm /Library/LaunchDaemons/at.obdev.littlesnitchd.plist

Answer 5

If you don't want to manually mess around with launchd, Lingon is a a graphical editor for it. Unfortunately, development of it has ceased, but it still works fine, and it's open source.
