I bought a used iMac G5 from Ebay that came with Leopard and Office 08 was the only software, no ILife. It's running great except for that annoying keychain password pop-up every 20 seconds, which I could probably live with. I emailed the previous owner for the password, he sent it to me, and it keeps coming up as invalid. I just tried to install ILife 08 that I purchased at the Apple store and it won't let me without a password. I am not a computer genius by any stretch. I am at a loss what to do. Is there any way to reset the password? The computer did not come with any disks, so I can't start over that way. I have no software on the computer and can't install any! Any suggestions would be greatly appreciated.
