why cuda does not support osx 10.4.x?

That’s an easy one: the graphics drivers for 10.4 don’t support CUDA. Its the best reason to upgrade to 10.5 ;-) (and I think 10.5.1 at that - but we’re upto 10.5.4 now).

On a somewhat related note, I wonder if NVIDIA has to submit graphics driver updates through Apple for inclusion in a point release, rather than releasing them direct on the website. I’ve been wondering if the hold-up on CUDA 2.0 for the Mac is manpower or if the driver is stuck in an internal Apple testing release, waiting for 10.5.5 (6,7…).
