Hi Stephen,
just used the terminal to check and it seems as though I can run with complete 64bit support.
Here are some infos about my MBP:
Modellname: MacBook Pro, MacBookPro4,1, Intel Core 2 Duo, 2.4 GHz
L2-Cache: 3 MB
RAM: 2 GB
Bus: 800 MHz
I bought it in August 2008.

My 2008 black MacBook has a 64 bit efi, does that mean it will run in 64 bit? This seems to contradict what the table says regarding 64 bit support.

to edit my above comment- ah, nevermind. I just read your latest entry, and better understand what you're talking about with the 64-bit support.
I do think we'll see it though, on the Santa Rosa models. There's nothing to keep them from supporting, as the hardware and firmware is there.

The 2007-2008 Nvidia-equipped MacBook Pros (Santa Rosa) are 64-bit, have 64-bit EFI, and are supported as such by Apple, so you may want to edit your chart.

*MacBook Pro (Nvidia graphics) from 2007-early 2008

In case you're curious, they're also supported for OpenCL. The 8600s are also H.264-capable, so I'm not sure why we don't get that with Quicktime yet. Maybe it's a driver issue of some sort?

I have MacBook white (2009-present) and Mac Mini (2009) and they have both 64bit EFI.
Thank you!
