I bought a used 2.16 macbook and it arrived today. the machine is immaculate from an external appearance, but when it boots up it of course goes to the user name and wants a password! of course the person i bought it from made no mention of this and of course they dont remember the password. story is that it was changed by their teenager and they didnt remember what it is. it has leopard on it. is there a way around this? the original discs were not included. i know how to go that route as ive done that with my ibook before. am i just out of luck? is it possible to buy the snow leopard upgrade, install it and reset the password?? any help would be greatly appreciated!!
