Tired of OS X Mountain Lion notifying you of things? Sick of the little menu bar icon in the upper right corner of your Mac’s screen? Do you not even use Notifications at all on your Mac? You might, then, want to get rid of the entire thing, disabling it completely and removing the icon from the menu bar.
We’ve got two ways to show you, one that’s more permanent than the other. Check it out.
For a more temporary fix, launch Terminal app from the Utilities folder, which is in the Applications folder. Once it’s open and ready, type or paste in the following command (be sure to copy the whole command, from launchctl to .plist):
launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
This will get rid of Notification Center only for you as the current user; it does not need admin access. Next, to restart the process, type or paste the following:
Go ahead and quit Terminal app, and the Notification Center icon should be gone from the menu bar. To put it back together, open Terminal app one more time, and type or paste the following:
launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
Get into your System folder, then open the Library folder, then open the CoreServices folder (or hit Command-Shift-G and type in /System/Library/CoreServices/ to get there super fast). Find Notification Center in there and double click to launch it again.
For a deeper solution, get into the CoreServices folder as above, and find Notification Center.app. Rename this to “Notification Center-disabled.app” with a click on the file name, and be sure to type in your admin user name to authenticate the change in the Finder.
Next, launch Terminal app and type the
killall NotificationCenter command to restart the process. Quit Terminal when done, and Notifications will be so far gone from your system that you won’t see them at all, and any hot corner or multitouch gesture to invoke it will just give you a blank sidebar on your screen.
If you want it back, though, just re-rename your file back to Notification Center.app, and double click to launch it. All will work again as it did in the first place, menu bar icon and all.
