I'm trying to help a friend upgrade an old iMac that he bought on eBay. The trouble is that the previous owner did not clean the system before shipping it. When we try to do a clean install of Panther, it says it needs a firmware update. In order to do the update, we have to have the password, right? Well, I did reset the password in the installer menu, but when we try to log in with the new password, it doesn't let us in. We just want to wipe this thing and start from scratch, but we can't figure out how to get past this. Now, when we go back to try to change the password, it won't even show any users on the drive. I've tried over and over again to do the installation, but it always says it needs the firmware update, which is fine, but I have no way of giving it the update it so desperately needs, unless it allows me to log in to get it. Please help if you know how to get around this. Thank you so much MacRumors folks.
