There is a Cuda driver at NVIDIA available for MAC.
Is there any support for pytorch on MAC for Cuda?
My MAC:
Power Book 15"
OSX 10.15.7
No, since macOS support was dropped in CUDA 11.0.
Thank you! 
Very precise.
No, but that is an irrelevant question since Apple didn’t use CUDA-relevant GPU hardware in its Intel era (at least in my experience), and then with the M-family hardware we now use PyTorch with MPS libraries instead of CUDA to get full hardware acceleration on Macs.
