[QUOTE="vansmith, post: 901043, member: 71075"] Yes, it is conceivable that Apple could remove this limitation. That said, you don't want to run a 64-bit kernel now anyway because of the lack of 64-bit driver support (a 64-bit kernel can only load 64-bit kexts). It's not a hardware issue (in terms of EFI) as illustrated by the article I previously posted - the "limitation" that only allows a 32-bit kernel to be loaded by a 32-bit EFI is artificial. The only hardware limitation that affects the loading and use of a 64-bit kernel and applications is your processor. If you're machine has a 64-bit capable processor, you can run a 64-bit kernel and applications. So, if you have a 32-bit EFI, you can load a 64-bit kernel (assuming the EFI limitation is removed by Apple) as long as you have a 64-bit capable processor. [/QUOTE]
