I have an IMac Pro.
I wanted to install Windows 7, so I created a partition with
Bootcamp, and installed Windows 7. Everything was fine, Windows was working and the Mac too.
After two days, I started the Mac, and it just got stuck at the loading screen.
I waited for one hour, and it didn't start. The 2nd time I booted the computer in Mac after that problem, it got stuck again, and a rare loading bar appeared.
Since that day, Mac doesn't boot, I don't know if the bootcamp or Windows is doing something to my Mac partition.
What could be happening?
I tried to repair the OS, I verified the disk, and repaired it. It says that there is a problem with the B-Tree catalog, and the system can not be repaired...
