I'm not sure why you can't run that, perhaps it needs more shared memory than you've got. You can try halving THREADS in cuda_wpapsk.h and rebuild.
However, you should be able to build macosx-x86-64-opencl or macosx-x86-64-gpu (which is both CUDA and OpenCL) instead. Then use wpapsk-opencl. This format is supposedly faster anyway (it does more of the work on GPU), and it auto-tunes to your device.
