My friend purchased a used Macbook and needed to reinstall Leopard on it (to remove the previous owner's junk), so he borrowed my install DVDs. Alas, the first DVD got stuck in the combo drive, so he had to send it in (under Future Shop's Product Replacement Plan, not under AppleCare, but FS sent it to Apple for repair). When he got it back, many weeks later, the DVD didn't work and could not be booted from. Will Apple give me a replacement? Does it matter which one of us calls? I'm thinking they might want the serial number to find the incident information, and since it's his Mac that was sent in, that he should call. Worst case scenario: will they let me purchase a replacement OEM DVD (with iLife and everything that came with my Macbook)? Anyone know how much? Thanks.
