Brought the original Intel iMac down as the kitchen computer and nobody had updated it is some time (it's at 10.4.10) and the Admin password has been forgotten. I don't have the original system disks or a Tiger disk, but do have a Snow Leopard disk. So here' the weird part. I can't pop the SL disk in because when I do and ask it to upgrade, it asks for the admin PW before rebooting. Oops, don't know it. Then I thought I could do an admin pw reset by booting from the SL disk, or at the very least do a fresh install of SL from there. Great, I thought I would reboot, hold down the C key until seeing the gray Apple (also tried holding until the spinning gear), but the system doesn't boot off the CD for some reason after that with the SL disk in the drive. Now I am really stumped. How can I reset the PW or do a clean install? HELP!!!
