Uninstall Little Snitch 4

For instructions how to uninstall Little Snitch 5, see here.

In order to perform its duty, Little Snitch needs to add components to a very low level of the operating system, which also need to be registered and unregistered with the system. It is therefore not sufficient to just remove all of Little Snitch’s application bundles. Instead, Little Snitch Uninstaller must be run.

Little Snitch Uninstaller

The easiest way to open the Little Snitch Uninstaller is to drag Little Snitch Configuration from the Applications folder to the trash. Little Snitch’s background processes notice this and automatically start the uninstaller that is located in /Library/Little Snitch/Little Snitch Uninstaller.app.

Alternatively, the Little Snitch Uninstaller can be found in the Little Snitch .dmg disk image file, next to the Installer. If you don’t have the disk image at hand, you can always download the current version from our website.

The uninstallation process itself is straight forward, with only one option to choose: Whether you want to remove your rules and settings or not. After the process is finished, you must restart your computer.

If you enable the option to remove rules and settings, the Uninstaller deletes all your system-wide configuration and rules files (also any files from older Little Snitch installations), including the file that stores your license information, as well as the configuration files, rules files and log files for the user executing the Uninstaller.
