Hi everyone, here's what's up and I'm hope I'm on the right track? My Imac 1.83 took a crap last Thursday, so I bought another Imac, which is a Imac 2.0. The person i bought the Imac from says he lost his leopard install disk, but it currently has Snow Leopard. I want to be legit and wipe his Snow leopard clean cause I have all my original install disk's, from Tiger to Leopard & Snow Leopard. Can I use my rightfully owned install disks on this machine?. Thank you all and have a great week.
