New to mac's and need some guidance. I came across an open box imac (2.4 GHz) at Best Buy tonight and bought it. It was supposed to have been purged/reset or whatever you call it. When I powered it up, the setup assistant didn't run and it looks like the computer is named for the original owner. So, is there a way to force setup to run so that I can name the computer and create my account? Doesn't look like there is any data so I was wondering if reinstalling from the setup discs is a better option? Sorry, probably a very basic question but..... Thanks in advance!
