Disable Notification Center & Remove the Menu Bar Icon in Mac OS X

  • Open Terminal and enter the following command:
    launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
  • Next type the following command to kill NotificationCenter:
    killall NotificationCenter
  • Finally, quit out of Terminal and return to Finder

This unloads Notification Center for the current user only and does not require admin access.

To re-enable Notifications with this approach:

  • Launch Terminal and enter a similar command – notice load instead of unload:
    launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
  • Hit Command+Shift+G and go to /System/Library/CoreServices/ then find “Notification Center” and double-click it to launch it again
