    My Mac book encounters a Kernal panic when the loading cog appears after the apple logo. I am trying to restore OS X but I have an open firmware password enabled which I cant disable. Is there a way I can restore OS X in single user mode or bypass the open firmware (efi) password.

    You can bypass the open firmware (or EFI) password by changing hardware.
    Try removing RAM for instance, and rebooting then.

    You can boot in Single User mode by pressing (anf holding) <COMMAND> <S>, until you see the CLI prompt.

    Maybe a disk check can help you there...
    You can do that by typing (at the prompt):
    fsck -fy <ENTER>

    Good luck.

    Hmm, I tried removing the RAM but i still cant boot from the CD...

    I got access to single user mode but found no errors.

    I was hoping to try and resolve the issue myself rather than being bothered going to an apple service centre...

    damn efi passwords.
