Hi, I am trying to help a friend out with his Mac. Its an old PowerBook G4, I am not even sure of the age but its got to be close to 6-7 years old. Anyways he had a power outage/maybe Surge in his house and now every time he boots up his Powerbook it ask for "Name" and "Password". Its not the normal user screen and none of his names or passwords work. Can anyone give some advice or at least point in the right direction? Thanks in advance.
