For some reason on my rMBP every time I reboot Yosemite it resets my notification centre preferences. I keep turning off notification banners for the default Twitter and numerous other apps but they always return on reboot. Only happens on my rMBP and not my Mac mini. I've repaired permissions multiple times, tried to search for corrupt preference files and deleted anything I can see to do with notification centre but no luck. Anybody know anything else I can do?
