    Hello people. Hoping someone can help me out.

    I have a GTX 780 6GB flashed by MacVidCards. I finally moved to Yosemite. Currently running 10.10.3. Got the latest web driver from nVidia (346.01.02f01) and it works. Only thing I cannot get to work is CUDA. I have tried the following CUDA drivers with no luck.

    6.0.51
    6.5.18
    6.5.25
    6.5.37
    7.0.36

    Any ideas on what I should try next? Everything was working on Mavericks. I used CUDA 6.0.51 and just ignored the "update required" warning at startup and everything worked great.

    Thanks in advance

    Updated web driver to 346.01.02f04 which works fine but still no CUDA.

    I also have a MVC flashed GTX 780, though mine is a 3GB model. I am running the same Nvidia Driver you are and Cuda 7.0.36. Cuda is working fine for me.

    Did you try CUDA 6.5.51 ?

    Well that sucks for me. I have the same drivers at @flowrider and no Cuda. Cuda-Z won't run and Adobe software says GPU rendering not available.

    @Synchro3 I just tried 6.5.51 and it doesn't work for me either.

    Any ideas how I can troubleshoot this?

    You have the actual version of web driver and CUDA installed. I don't see why it should not work.

    Maybe an old CUDA-Z version? Actual is 0.9.231: http://cuda-z.sourceforge.net

    If you have Adobe Premiere CS6: right click on Premiere application-> show package contents -> Contents -> open 'cuda_supported_cards' with a text editor, and add 'GeForce GTX 780' .

    If you have done this start a new project in Premiere. You should now be able to select the Mercury Playback Engine GPU acceleration (= CUDA).

    Same thing with Adobe After Effects CS6: Add your card with a text editor to 'raytracer_supported_cards'

    @Synchro3 You were absolutely right. I downloaded the latest Cuda-Z and it works. CUDA has been working the whole time and I just didn't know it. Another bonehead mistake solved by MacRumors and its great members. Thank you!
