My friend gave me his 10v to fix, and the problem is that it when booting, it gets stuck on the Apple logo with the spinning wheel. Before that, however, the Apple logo will show up with a progress/loading bar that shows up at the bottom which has never never been there before.
Unfortunately, we're not sure what caused the problem. We're assuming that someone must've updated the OS by accident, but we don't know for sure if that is actually the problem or not.
To make things worse, I'm not even able to get to the command prompt to enter safe mode (or any other mode for that matter), so I'm pretty much stuck
Any ideas on how to get this thing to boot?
