I’ve just acquired a second-hand iMac 1. It is booting up to the desktop but the user account it is logged in with has a password, and I don’t know this, or the supervisor password. Is there any way I can create a user account for myself, or change the password for the logged in account without knowing it… I’m assuming not. Is my only option to re-install the operating system? This could be a slight problem as I don’t have the disks. I can probably get some system disks, but as you probably guessed I’m pretty new to new Macs (I still have my classic though) so do I need some sort of install key to re-install the operating system? I’m not trying to do anything illegal here. The current op is valid, and I would just be re-loading the same version, so I can get a clean install.
