Hey everyone, As I mentioned in a previous thread, I'm selling my iMac to buy a MacBook. The MacBook (2008 uMB) has arrived, with all the discs etc, which is brilliant. My iMac however, came preloaded with Tiger, with a Leopard upgrade disc in the box. This Leopard disc has disappeared off the face of the planet, and so Apple are shipping one out to me, not sure when it will arrive. In the meantime, my auction ends tomorrow, so would it be possible to restore the iMac using the Leopard discs that have come with the MacBook, or is it safer to reinstall Tiger, and wait for the Leopard disc to arrive before shipping? Many thanks.
