I found a dumped imac g3 strawberry in our neighbourhood. With a new cord, it works however I would like to install a faster operating system on it and am coming up with a few problems. First of all, obviously I have no admin rights. This imac looks like it used to belong to a school and then someone must have bought/was given it and has their own account also. (Shouldn't the school have wiped all the data off of it before handing it to someone else???) I have no idea how to get admin rights and so far everything I have googled has not worked (eg: will not boot into single user mode... Don't know if I am using the wrong keys considering I am using a pc's keyboard with it) How do I gain admin rights? Do I need admin rights to install a new operating system? -panther or jaguar. I haven't chosen yet. If anyone could help me out I would be grateful thank you.
