Start up stuck on gray screen with apple logo on startup
I have tried booting in Safe Mode by pressing shift, but after I see the bar load it goes right back to the apple with the spinning wheel.
I tried refreshing the pram (command option p r) and that didn't do anything.
I tried shift command v and the last line that it got stuck on was BootCache Control: could not unlink bootcache playlist/var/db/bootcache.playlist 22 invalid argument. Then it just stopped there.
Also, I am running Mountain Lion on Mid-2010 Macbook Pro.
Any suggestions?
