What does the error mean?

>> A = gpuArray( rand(1024) ); 
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 could not be loaded. The library name used was
    '/usr/local/cuda/lib/libcuda.dylib'. The error was:
    dlopen(/usr/local/cuda/lib/libcuda.dylib, 10): image not found

I would reccomend updating/re-installing your graphics driver to see if that solves the problem.

Will do that and see if it works, thanks.

No, as pasted in the comment above all I have is just Intel HD Graphics 4000. So no way to use GPU in MATLAB?

Note: eGPU on Mac only officially supports some AMD Radeon .

However: Your MacPro mid 2012 13" appears to be model MacBookPro9,2 with 1280 by 800 resolution internal. That model has two USB3.0 connectors, and a Firewire 800 connector, and a Thunderbolt 1 connector. You would therefore not be able to use any of the external GPUs that need Thunderbolt 3 connectors.

I happen to have the very next model up, the mid 2012 15.4 inch, which I took the upgraded display resolution on. It has a GeForce GT 650M as well as HD 4000. However, I effectively do not use that system now; the memory limitations (8 Gb) were getting tiresome, and the hard drive started to whine.
