Looking for some temporary peace and quiet from alerts and notifications but don’t want to completely disable Notification Center on your Mac? There are two quick ways to temporarily hush all notifications in OS X, both methods last until the next day before automatically resuming:
- Option+Click the Notification Center menu bar icon, it will turn grey when disabled
To re-enable Notifications, just option+click the menu bar icon again. It will turn black to signify that it’s active again.
If you’re less of a keyboard fan and more of a gestures person, you can also hush notifications directly from the panel itself:
- Swipe open Notification Center, swipe down, and flip “Show Alerts and Banners” to OFF
Flipping the switch back to ON, or option+clicking the icon works to re-enable alerts again. Here is a quick video showing both of these methods in use under OS X Mountain Lion:
