Radio Silence 3.4 for Mac
Mac UtilitiesRadio Silence takes the simplest possible view of a firewall. Some apps should not be online. Maybe they phone home too often, maybe you just want them quiet while you work. Add an app to the block list and it stays offline until you remove it. No pop ups asking questions, no rules to write. Alongside the list sits a live monitor that shows every connection your Mac makes, including the hidden helpers you never see.

FAQs
Does Radio Silence block single websites?
No. It works per app by design. An app on the list is fully offline, and an app off the list is fully online.
Will it interrupt me with alerts?
No. There are no connection prompts. You decide the list in advance and the app follows it in silence.
Is it a subscription?
The vendor sells it as a one time purchase with a short trial and a money back guarantee. Check the official site for current terms.
