Radio Silence
A firewall for macOS that blocks apps from internet connections.
Radio Silence is a firewall and network monitor for macOS that lets you block individual apps from making internet connections while showing every network connection in real time. It runs invisibly in the background without open windows, pop-ups, or menu bar clutter, and is designed to work without requiring network expertise.
The network monitor displays connections as they happen and lets you block a misbehaving app with a single click. It surfaces helper apps, invisible background processes, daemons, and XPC services. Child processes of blocked apps are automatically blocked as well, while blocked apps can still communicate with local processes. It supports macOS 10.15 or newer on Apple Silicon and Intel Macs.
Radio Silence is aimed at Mac users who want to see and control which apps access the internet. It is available as a free trial and a paid license, with a 30-day money-back guarantee.
