What is the best way to enable Snow Leopard to boot into 64-bit automatically? I can't use the ole 6-4 trick with the bluetooth keyboard. It works fine if I use a wired keyboard and I don't want to have to dig out and attach a wired keyboard everytime I re-boot my Mac.



This Mac is definitely 64-bit (Quad Core i5).



Any terminal hacks or software hacks or downloads would be good.



Thanks!

    You can set this in your NVRam by typing the following in your terminal, just paste it in exactly as is:



    sudo nvram boot-args="arch=x86_64"



    If something messes up for whatever reason, you can reset PRAM holding command-option-p-r at boot. Doing so will also default it to boot in 32-bit.

    There is a free application called K64Enabler that will enable 64-bit booting. This is what I use.
