I have been hearing some conflicting info about compatibility. Perhaps nobody knows the answer to this yet, but I'm wondering if I'll be able to run 10.7 on my original Mac Pro. Apple states that a core2duo chip will be the minimum requirement to run 10.7. However, there have been many saying that 10.7 will run exclusively on a 64-bit kernel, and the only Macs that can currently run on a 64 bit kernel must have 64 bit EFI. the original Mac Pro has a 32 bit EFI. So I'm confused. Will the original Mac Pro be able to run 10.7 or not? If not, I'd like to know so I can sell my Mac Pro now for a newer machine that will be able to run 10.7. Thanks for your thoughts.
