Thanks for the hint ("beast" descibes it perfectly :) ), seems mine is castrated: "Furthermore, it appears that although subsequently released MacBook, MacBook Air, and pre-"Mid-2010" Mac mini models all are equipped with "Core 2 Duo" 64-bit processors and 64-bit EFIs, Apple has blocked these "consumer-targeted" Macs from booting in 64-bit mode. iMac and MacBook Pro models released in 2007 with 64-bit EFIs seem to have been blocked as well."

Ouch, I had forgotten about those specific devices. I had a Mac Mini Core Duo that I had upgraded to a Core2 Duo and was never able to get Snow Leopard to boot into 64-bit mode. I was able to get Linux and even OpenBSD installed on it using the previously mentioned bootia32.efi method. Also, you may be able to boot 64-bit macOS on your system if you follow the netkas.org link from your everymac.com link: http://netkas.org/?p=189 http://netkas.org/?p=189

  Thanks, but no tampering with this system anymore until I have a replacement on the desk... Remember: Never touch a working boot setup an old Mac with a crippled EFI. ;)
