Hey guys, I got OS X 10.8.3 running on my MacBook Pro 15'' Retina, and sometimes when I wake my notebook the theme of OS X changes to black. The notification center changes to red, my dock changes to black and my Apple logo on the top left fly's away. Could someone explain this to me? Maybe it's going to be a new theme for OS X users? Are there more users experiencing this on OS X 10.8.3? Edit: It seems to be a bug, nothing to be worried about! Thanks guys!
