How to: Disable Notification Center in OS X Mountain Lion
Whether you hate notifications in toto or want to disable Notification Center in favor of Growl, which really isn’t necessary, here is how to get that done. As is always the case with command-line magic (bookmark this page), it is super easy turn it back on — give it a go.
Some folks like notifications — count me in. Further, although Notification Center is new in OS X Mountain Lion, Growl has been the go-to third-party solution for years and there are those that very much prefer the once-upon-a-time free system add-on (Mac App Store, $3.99).
Disable Notification Center:
launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
Re-enable Notification Center:
launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
