Where Does Little Snitch Store Rules?
Little Snitch rules, configuration and logs on macOS.
Last updated
Little Snitch keeps connection rules, profiles and factory defaults in system Application Support, with logs and snapshots beside them. Editing raw rule files by hand corrupts signatures, so export through the app.
Export rule groups before macOS upgrades and clean installs. A thousand per-host decisions rebuild slower than any installer.
Where Little Snitch stores this, by platform
/Library/Application Support/Little Snitch
System rules, configuration and defaults for all users. Per-user prefs sit in ~/Library/Preferences beside it. Back up with in-app File Export, not Finder copies. Logs live in /var/log alongside.
Frequently asked questions
How do I back up Little Snitch rules?
Export configuration from inside the app to a portable file. Raw copies of the folder above miss signatures and restore badly.
Where are Little Snitch connection logs?
In system logs beside the folder above plus in-app Network Monitor archives. Use Monitor history for per-connection forensics.
