I have a mac pro, with a nvidia quadro 4000. I am running Blender 2.63.
When I go to set up cycles to use the gpu, it does not show that I have option to use the quadro 4000.
in the compute device box it says: None
and the drop down only has CPU
Thanks

What Blender Version (from where) are you using? Maybe try http://graphicall.org/856
and try cuda driver 4.2.9
I tried both… still no success.
Same problem… I updated CUDA drivers, and tried that Graphicall build (which crashed immediately). I even sent a message to the dev’s (hope I don’t annoy them)…
The Tomato build seems to work…
if you mean my tomato build: The biggest difference to Blender Trunk is: Tomato is built with gcc 4.2 - Trunk (official/mine) with gcc 4.6.3
No idea though if this can/is cause the issue.
Let’s see what the dev have to say. You report it back here?
The Quadro 4000 supports the CUDA computing capability 2.0, which is supported by Blender in general.
But our official Mac builds don’t come with CUDA render kernels, so for now you have to rely on a build from graphicall.org, which contains the rendering kernels (just look for a build with the info “with CUDA” or something like that.
The alternative is to download the CUDA toolkit: http://www.nvidia.com/object/thankyou.html?url=/compute/cuda/4_0/toolkit/cudatoolkit_4.0.17_macos.pkg (requires OS ver. 10.6.8 or higher) This way your computer will build the needed kernels when you first try to render with Cycles, GPU.
