Sorry folks, I might not be in the right forum / thread - I just saw lots of people on this one at this hour . . . . And, I'm not a MAC user but am trying to help a friend with a MAC issue . . . . Her Safari crashed and not knowing what else to do she reinstalled her OS - said it was 10.4. Now she can't get into the MAC at all. She doesn't know the default user id and password. She said her screen shows the machine name, but won't take her original uid / pw. I'm guessing the OS reinstall reset it to some factory defaults. What uid and pw should she try? THANKS !!!
