How to block Safari from the Internet on Mac OS X

Blocking Safari with the Radio Silence firewall is just as easy as blocking any other app. Blocking Safari can be useful for web developers, when you want to work with local files but prevent all real network communication.

Remember that Radio Silence comes with a free trial and has a 30-day money-back-guarantee, no questions asked.

  1. Open Radio Silence. You can do it from your /Applications folder or using Spotlight. Launch Radio Silence with Spotlight
  2. Click the "Add Application…" button. Add an application to Radio Silence
  3. Select Safari. You can find it in /Applications/Safari.app.
  4. Done! You can now close Radio Silence. The firewall stays active, even after you close the Radio Silence app window.
