The Mac Pro 1,1 has 32-bit EFI and will not boot into 64-bit mode. I tried both of the references you cited several months ago and eventually gave up. My 64-bit apps do run and the prevailing opinion seems to be that the 32-bit EFI should be able to boot into the 64-bit kernal but that would require a firmware update from Apple. It seems Apple would prefer that I buy a new Mac Pro rather than update the one I already own. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
