Okay so, I just got my iMac (24" aluminum) back from being repaired (hard drive failure). Got it home, then set everything up. -There's a chip in the aluminum on the top left. -They used my name for the home directory (which is how it was originally setup)...but spelled my name wrong. From what I understand, you can't easily change this? -They used a different password, and I have no clue on what the new password is (I suppose I can just call them tomorrow to find out). When I dropped it off, the "genius" said it would be setup as a new computer and I could restore everything my time machine backup...apparently, this is not the case. Is there anyway to restore everything back to factory settings and restore from time machine? Would this fix the home directory name? And finally, I'm not sure there is anyway to prove that the chip in the aluminum wasn't there when I gave it to them, so am I screwed on that front? The chip is fairly small, but I tend to be anal about stuff like this, especially if I didn't do the damage myself. Any ideas?
