Remove duplicate menu bar icons in macOS Sierra When I upgraded to macOS Sierra, a lot of my menu bar icons were duplicated. This included time, wifi, AirPlay, and Notification Center. I've been able to remove all of them except for Notification Center. 

Any thoughts?
Drat... shortly after I posted this I found a way to kill off the SystemUIServer which was just the kick it needed. 

killall -KILL SystemUIServer


PS: I searched before I posted originally. :)
