We’ve covered some Notification Center tips at TekRevue, but what if you just don’t want Apple’s notification platform at all? Here’s how to indefinitely banish it from your Mac.
Note: this tip was originally written in April 2013 and tested on OS X 10.8 Mountain Lion. Like all system modifications, it may not work with newer versions of OS X.
First, launch the Terminal app from /Applications/Utilities, enter the following command, and press Return:
launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
You’ll see the Notification Center icon disappear from your Mac’s menu bar. You may notice that there’s now a blank space between your rightmost menu bar icon and the edge of your screen. Simply click your Desktop or a Finder window to refresh the menu bar and watch as your icons line up perfectly, with Notification Center banished for good.
If you have a change of heart and want to restore Notification Center, hop back into Terminal, enter this command, and press Return:
launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
Just as fast as it disappeared, Notification Center will pop back into your menu bar and all of its features will be restored.
Disabling Notification Center via this method will survive a reboot and only affects your individual user account. Guest accounts and other users on the same Mac will not have access to Notification Center altered by this command.
