To reset the administrator password using the Mac OS X CD:
1 Insert the Mac OS X Install Disc 1 CD and restart the computer.
2 When you hear the startup tone, hold down the C key until you see the spinning gear.
3 When the Installer appears, choose Installer > Reset Password.
4 Follow the onscreen instructions to change the password.
5 Quit the Installer and restart your computer while holding down the mouse button to eject the CD.

- yap

Manage with my friends help to unlock the firmware lock the press C is not working because the firmware lock anyway tq to slamdunk for his help. Tq for everyone for helping

Woah this is not nice... the way chopsuey mentioned should work I believe. There's definately a way to solve the problem...hmm how about e-mailing Apple about it? They know much more than we do that's for sure.

If you still remember your username, restart your mac, then as follows:

- Hold Apple+S when booting to enter single user mode
- #sh /etc/rc
- #passwd yourusername
- #restart

This is to reset your password.
Hope it helps.
