Am I running 64-bit on SL?

[AreYouAMac]

I have the Blackbook 4,1 (2.4gh) - but I know by default SL runs 32bit on startup. This is SL 10.6.0

But via Activity Monitor - I see Intel (64-Bit) running on most of my programs.

Anyways - I thought programs are suppose to be running 32bit via SL since the macbooks/pros/imacs/ everything else besides XServe are efi 32bit?

the apps and everything can run in 64-bit mode even if the kernel is 32-bit. looksy.

K - That explains it. No need to boot into 64 bit SL. So I wonder why everyone was fussing over that.

Well - I guess I will have the best of both worlds. Windows 7 64 bit and SL 32/64 bit also.

No Macbook (as opposed to Macbook Pro) will boot the 64-bit kernel. It's an intentional limitation on Apple's part.
