After spending last weekend trying to fix my Mac, yesterday I backed up my account, erased everything, installed MacOS X from scratch and recovered from the backup.

The whole process did take about 6 hours, but everything went amazingly well, and my system was back with all my stuff. For the kind of magic that always happens when you do this kind of operations, I actually got 10Gb of additional free space on my drive.

But the issue I originally had with strange screen artifacts in Aperture it's still here. So I'm back to square one, on the phone with Apple support (but with a brand new 500Gb external drive and a full backup).
