intel imac lost admin password
iMac Intel core 2 duo 20” OS10.5.5
I picked up this computer on an eBay auction. On receipt it works fine but it has no administrator password. I had not expected this to be a problem, as I was going to do an erase and install using system disks. However there is a problem. I cannot boot the computer up from disk using the c key, nor can I boot it in single user mode using cmd-s. Does this mean that the mac has had open firmware password protection activated, and if so is there any way I can install a new system without the admin password?
