I dont know my administrators name and password for my G5 iMac. I have tried t change it using my install disk but it didn't work. Said there was some kind of failure? I don't think I have ever known the password? I had apple care when I first purchased in 2004.


Mac OS X (10.5.8)

    I bought a used Mac and didn't know the administrator's password. However, since it was already scrubbed and erased by the previous owner I had no data to lose. I think I just erased everything again and reinstalled Snow Leopard. That allowed me to put in a new administrators password.
