MacOS
MacOS is a useful visual environment. NVIDIA support is only for 10.13 or below and will likely require an external GPU with 6Gb of NVIDIA RAM with CUDA support. CPU versions are also available but are best used for background batch calculations. see for NVIDIA and macOS 10.13 see https://www.nvidia.com/en-us/drivers/cuda/macosx-cuda-410-130-driver/
