Hi guys, I just purchased a new iMac yesterday and would like to wipe my old one clean so I can get rid of it. I purchased it from eBay and it didn't come with any disks at all. I purchased the snow leopard disk to upgrade it about a week after I received the iMac so I do have that disk, but that's all. So how exactly do I go about wiping this thing then? From what I read, you need to have the original disk or disks that came with the computer?
