Cycles Render on GT750 GPU (MacBook Pro) 2GB Graphics - 2.79 Blender I have a GT750 Graphics Chip in my MacBook Pro, it has 2GB of dedicated VRAM, I would like to use this to render rather than the CPU. 

The MacBook also has a Quad Core i7 2.6GHz and is able to render using the cycles engine perfectly, however looking at benchmarks even though the GT750 is not a hugely powerful chip, it should still perform better than the CPU. 

I have gone onto NVIDIAs site and downloaded and installed the latest CUDA Drivers, and then restarted my Mac. I then went into 'User Preferences -> System' and only OpenCL is available, there is not a option for CUDA. Please see the screenshot.

If I go ahead and use GPU / cycles rendering on OpenCL the application just quits without any errors shown. 

This is using Blender 2.79 

Thank you for any help
OpenCL does not work (yet?) for Blender on MBP with NVidia. It worked with CUDA for me on mid 2014 MBP with GT750M 2GB Nvidia but I had to install the latest NVidia drivers and CUDA, however the result was extremely disappointing, pretty much the equivalent of single core CPU rendering instead of 8-core! Don't waste your time with this with the GT750M.

Since the NVidia GEForce drivers are not stamped by Apple, they are hard to find even on the NVidia website. I used this site as source of the NVidia link! https://www.tonymacx86.com/forums/graphics.13/

At the time of this post, the latest drivers are http://www.nvidia.com/download/driverResults.aspx/130460/en-us

... which also includes the link to download CUDA...
