Maverick already installed and now reinstalling???
Maverick is already installed properly. I have been using my laptop fine all week. Powered up today and now it's stuck in 'setting up your computer' grey screen.
MacBook Pro, iOS 7.0.4
Shut the computer CLEAR OFF and wait a couple of minutes and Power it up.
Go to the Black Apple and Do a Software Update.
Restart again and see if that dose the trick
Cheers
Don
