Mute Notification Center Alert Sounds in OS X Mountain Lion
Notification Center is a great addition to OS X Mountain Lion but the alert sounds can be pretty annoying if you have a lot going on. Rather than muting all system audio to hush the constant chiming, you can directly silence notifications on a per-app basis.
- Open System Preferences from Apple menu and click the “Notifications” menu
- Select apps from the left and uncheck the “Play sound when receiving notifications” box
- Repeat for every app you want to silence
This better than disabling Notifications completely because you’ll still see them arrive, but you won’t bother your coworkers with beeps and boops anytime it’s your turn in Chess.
If anyone knows of a way to turn off alert audio for all notifications in OS X, let us know in the comments!
