Little Snitch Network Monitor
Little Snitch Network Monitor is a privacy-focused personal firewall and network monitor for macOS that alerts users whenever an app attempts to connect to the Internet. It allows users to allow or deny each connection, track and analyze network activity in real time, group connections by app, domain or country, and create custom rules to control which apps can communicate with which servers. The app includes DNS encryption, blocklist management, rule automation, and usage statistics. It has been a popular privacy tool on macOS for over two decades, used by professionals, privacy-conscious users, and security researchers.
AI Recommendation
1 suggestionThe vendor's official website explicitly confirms that Little Snitch Network Monitor supports both Intel and Apple Silicon chips, so a native build already exists. If your copy is still running as an Intel-only build under Rosetta, update to the latest version from littlesnitch.app to get the native Apple Silicon binary. Launch Little Snitch, check Help → Check for Updates, or download the current installer directly from the vendor's website — the network monitor will automatically switch to the native build. No manual intervention or beta enrollment is needed; the main download page serves the native build to all users on M-series Macs.
