My MacBook Pro turns on, but all I see is the loading wheel- nothing else. What should I do?
My laptop froze while playing a video, so I shut it down and turned it back on- as usual. Only this time, it started showing the loading wheel and nothing else- I can't even get to the login screen anymore. Is there anything I can do about this?
MacBook Pro, OS X Mountain Lion (10.8.4), Late 2009 purchase
