I bought a new iMac the other day. I paid full price at retail and I was very happy with things. I spotted a refurb on the Apple store with what I think was the same spec but cheaper. I deciede to order this and return the shop bought mac and save some money Anyway, the Mac has just arrived and I have just restored from time machine. The Mac I bought retail was a 3.4Ghz i7 with 1TB HD and 1GB of Video Memory and 8GB of Ram. This machine has the i7, 8GB of Ram, 2TB HD and 2GB of Ram. On my invoice it just says Refurbished i7 3.4 iMac. I don't know if I just misread what was listed on the apple site. How do I check. Is there also any chance that if I return this for a repair under warranty I might get back a lower specced Mac? Finally - how do I go about wiping all info from the other Mac to return to the store?
