I wrote about my MBP which was vandalized a while back. Although damaged, I was still able to log in to it. If I sign in as root, or guest, no problem, but using my own usual profile, I end up eternally in the circling "wait" instead of logging in. It did get stopped while running earlier, but I had rebooted since then. I don't think this is the hardware but more likely something which caused corruption. I've tried checking the disk and correcting permissions. Disk test shows no errors. How can I fix this so I can sign back in to back up this MBP?
