This post will show you how to disable osx notification center.

the notification center on osx is a good idea, but I personally dont ever use it, so I figured that it was time to disable it, like the other osx features that I dont use

to disable the notification centre:

open terminal

type:

launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
killall Notification Center

the notification center will now be gone!
