1. The arbitrary limitation that if your computer 'only' as EFI32, Apple prevents you from booting into the 64-bit kernel.

MacOSX requires EFI64 to boot, probably because doing the bootstrap from 32- to 64-bit mode is a bit tricky. This isn't really arbitrary, but it is annoying, and is typical of how Apple tends to punish early adopters. My test lab has a lot of the original generation Intel hardware (1st generation Intel Xserves and MacPros). All these machines run 64-bit Linux (and FreeBSD, and OpenSolaris) just fine, but none will run MacOSX in 64-bit mode due to not having EFI64. This irritated me greatly, especially since the hackintosh people are booting whiteboxes into 64-bit MacOSX. What I finally did was to use the hackintosh "pc-efi-v10" bootloader to boot into 64-bit MacOSX on our 1st generation MacPros, using the Linux partition's grub bootloader to launch the hackintosh bootloader. Its all very Rube-Goldberg-ish, and it has all the disadvantages of a hackintosh (no decent video support, etc). But for what I need (an x8 PCIe slot in Mac running a 64-bit kernel), it works well enough. Why do you absolutly need to boot on 64 bit Kernel ? Does you machine have more than 32 GB of RAM ? _______________________________________________ Do not post admin requests to the list. They will be ignored.
