I bought Leopard on launch day to upgrade my MacBook. I just bought the new 8 core Mac Pro. Even though it comes with Leopard disks, just out of curiosity, will the retail box Leopard install disk work? Or is it missing drivers? I know the advantage to the bundled Leopard disks is that they also come with iLife 08. The next MacBook I'll buy will come with disks too. So at some point the retail boxed version will become extra to me. So should I keep this as a spare, or sell it on eBay? If it'll load on the Mac Pro then I'll keep it as a spare in case I damage my originals.
