MacBook6.1: How Start in 64 bit Kernel

Hello, i have macbook 6.1, Intel Core 2 Duo 2.26, 4 Ram. How i enable 64 bit Kernel ?, i use 6-4 hold keys aand the system reports :

64 bit Processor
64 Bit Efi
64 bit Kernel Boot
32 bit Kernel

so, also I have updated the file boot.efi modifying the hexadecimal content of the direction 0266D0 Hex with

01 01 00 00 00 00 00 00 0c 42 00 00 00 00 00 00

i made the changes to system in boot.efi and i use the folow command:

#systemsetup -setkernelbootarchitecture x86_64

someone can help me ??

thanxs a lot guys

Why are you editing boot.efi? That's a dangerous game you're playing if you don't know what you're doing. Avoiding editing boot.efi.

As for the 64-bit kernel, you can't boot into it because you're using a MacBook. Regardless of whether you have a 64-bit processor, you can't get a MB to boot into a 64-bit kernel. Take a look at this thread. Why are you trying to boot into a 64-bit kernel anyway?

Hello man, the answer it's simple : because my macbook it's my laboratory of experiments and i'm sure that it's not dangerous for hardware. if something failt simple i'm reinstall OS. that's all.

The hardware of this computer it's full compatible with 64 bits kernel and i'm study who i start in full 64 bit.

The processor of this computer it's : Core 2 Duo 2.26 ghz, 4 Ram, and i change the hard disk to a Toshiba Sata2 500 Gb

in this computer i'm install ubunto 64 bits and run fasttttt . why not int MAC os X ??
