Yosemite : No CUDA, no OpenCL GT650

--AG-- said:

Just installed Yosemite. Have a 15" rMBP 2.7 GHz mid 2012. For some reason neither my cuda coded applications nor OpenCL detects my GT650 card. "No Cuda device" if running cuda and only intel 4000 when running OpenCL. Anyone?

You need to use gfxcardstatus to force the GPU into NVIDIA-only.

Well... it happened with me when I upgraded my old Macs to Mavericks. I lost CUDA support for 320m and 9400m GPUs. The solution came months later as a hacked cuda driver package distributed by a user on this forum.

Fortunately, in your case you'll probably get a new cuda driver as soon as nVidia release a new version from its cuda driver. That's why I won't upgrade my rMBP at least while Yosemite isn't reasonably mature and it doesn't support all apps I use.

Or he can just uncheck automatic graphics switching in system preferences and it will be NVIDIA only.
