Little Snitch Overview
Little Snitch for Mac is an advanced network monitoring and application firewall designed to give you complete control over your Mac's internet connections. It alerts you whenever an app attempts to connect to the internet, allowing you to allow or block connections based on your preferences. Whether you're protecting your privacy, monitoring network activity, or preventing unauthorized data transfers, Little Snitch provides powerful security tools, real-time traffic monitoring, and detailed connection insights for both Apple Silicon and Intel-based Macs.
Track background activity
As soon as your computer connects to the Internet, applications often have permission to send any information wherever they need to. Little Snitch takes note of this activity and allows you to decide for yourself what happens with this data.
Control your network
Choose to allow or deny connections, or define a rule how to handle similar, future connection attempts. Little Snitch runs inconspicuously in the background and it can even detect network-related activity of viruses, trojans, and other malware.

What's New in 6.5 Version

Improvements:
- Compatibility with macOS 27 Golden Gate.
- App bundle integrity monitoring. Little Snitch now monitors the integrity of its app bundle not only at app start (like before) but also while the app is running, presenting a warning dialog if an unexpected modification of its app components was detected.
- Clicking an already selected location in the map (which filters the connection list to show only connections to that country/region/city) now clears that selection to reset the location filter.
- Using the term “traffic volume” instead of “traffic amount”.
- Improved appearance of search fields in inactive windows.
- Added an experimental implementation of NAT64 (RFC 6052).
Bug Fixes:
- Fixed an issue that prevented expired temporary rules from appearing under Suggestions > Expired.
