gpu Error: CUDA driver found, but returned an error. Error returned was:

I am attempting to use the parallel processing toolbox. I have a NVIDIA GeForce GTX 660M 512Mb GPU running on macOS 10.13.3. When I try to select a gnu device, I get the following error

    >> gpuDevice
    Error using gpuDevice (line 26)
    There is a problem with the graphics driver or with this GPU device. Be sure that you have a supported GPU and that the
    latest driver is installed.

    Caused by:
        The CUDA driver was found, but the function 'cuDriverGetVersion' returned an error. The error returned was:

However, there is no error that is being returned. It is just blank. I have just installed the CUDA toolkit and the latest drivers for MacOSx. I have restarted Matlab and the machine in between installs.

I don't fully understand the Mac drivers, but I do know you have to install both a CUDA driver and a kernel driver. How did you install your driver? Through the System Preferences or through the NVIDIA driver downloads page?

Update, I found a solution to this problem on the NVIDIA development forum:

This solution worked for me.
