I'm sure this has been asked a thousand times before, but I've seen some varying answers and nothing specific to Snow Leopard, and instead of wasting my time reinstalling several times to try them out, I thought I'd ask for myself. I recently (2 days ago) received a brand new iMac. I'm now going to sell it, and would like to restore it to the "right out of the box" state, where it will start the setup assistant when it's turned on...as if it were never turned on before. I saw some methods involving command lines and whatever, but I'm wondering if there is a simple way. Can I simply turn off the Mac at a certain point during the OS install to achieve this? Sorry if this question has been beaten to death, but I'm really curious. And if you're wondering, I'm only selling the iMac because I now regret not getting the quad-core! Thank you very much in advance!
