Little Snitch
brew install --cask little-snitch
v6.3.3
Application firewall that monitors and controls network traffic for each app on your Mac.
Why you might care
Reveals which apps are attempting to access the network, allowing you to block outgoing connections and prevent unwanted data exfiltration. Useful for privacy-conscious users who want visibility into background network activity and granular control over what connects to the internet. Requires paid license but is widely regarded as the best macOS firewall.
