Hi guys, I've got a 2008 13" MacBook Pro that I'd like to reset to factory settings, or as near as. It came with Leopard and I upgraded to Snow Leopard, but I still have the Leopard restore discs. How would I go about resetting this to factory settings, is it possible to downgrade OS? Or, can I just do a wipe and install from the Snow Leopard disc, keeping iLife? Ta very much.
