Little Snitch Helper
Little Snitch Helper is a component of Little Snitch, a personal firewall and network monitor for macOS that lets users see and control outgoing network connections from their Mac. The helper runs in the background and monitors network activity, enforcing rules that allow or deny connections to specific hosts or applications. Little Snitch is widely used by privacy-conscious users, developers, and security professionals to audit which applications are contacting remote servers and to prevent unwanted data collection or malware communications.

1 suggestionLittle Snitch Helper is not a standalone app but a system-level helper component of the Little Snitch personal firewall. You cannot update it independently — the helper is managed entirely through the main Little Snitch application. To get a native Apple Silicon build of Little Snitch (which will ensure the helper also runs natively), you need to update the main Little Snitch app through its own update mechanism. Visit Objective Development's website at obdev.at to check for the latest version of Little Snitch with confirmed Apple Silicon support, or use Little Snitch's built-in updater (Help → Check for Updates). The specific update channel depends on how you originally installed Little Snitch — direct download, Mac App Store, or another method. If you are still running an Intel-only build of Little Snitch under Rosetta 2, updating to the native version will improve both performance and battery life while ensuring your firewall continues to work properly when Apple removes Rosetta 2 support in macOS 28 (September 2028).
