I'm running into a problem with my Mac g4

I can't reset the password; I get an invalid prompt after doing the 'resetpassword' query. Is there any other way to unlock the account? It's a single user account.

I got Mac at yard sale and the people won't answer the door now ;( I'm frustrated!

    What sort of password is it? Does it prevent you from booting into OS X? Can't you just wipe and reinstall the OS?

  • Does it have Recovery Mode (Command + R during restart) that will allow you to erase the HDD and download OS X from Apple? If you can't download a copy of the OS then you'll have to borrow or buy it.

The best way is to enter the recovery mode while restarting Mac, and then erase the Hard Disk Drive. Then you must install a new version of OS X on your Mac.

Attention: All your files will be deleted after erasing the HDD.

NOTE: Enter the recovery mode by pressing ⌘-R while restarting Mac.
