Hey, I just received a PowerBook G4 from a member off the macrumors marketplace. But i have one issue. The PowerBook was sent to me formatted,so when i recieved it, I had to go though the Leopard intro. (which was expected.) The only issue is, after the intro it asks me to log into the computer. It doesn't have my name in the accounts section. and It will not accept my username or password. The only name listed in the accounts section is. "Other..." I've tried to re-initialize the "intro" sequence using Command-P, but the same problem occurs. Oh, and the seller's password didn't work either. What do I do?
