This section covers steps to install CUDA on macOS. It needs the *.dmg installer downloaded from the CUDA website. The steps to install after downloading the installer are as follows:

Launch the installer and follow the onscreen prompt to complete the installation. It will install all prerequisites, CUDA, toolkit, and CUDA samples.

Then, you need to set environment variables to point at CUDA installation using the following commands:

If you have not installed CUDA at the default locations, you need to change the path to point at your installation location.

  export PATH=/Developer/NVIDIA/CUDA-x.x/bin${PATH:+:${PATH}}
  export DYLD_LIBRARY_PATH=/Developer/NVIDIA/CUDA-x.x/lib\
                   ${DYLD_LIBRARY_PATH:+:${DYLD_LIBRARY_PATH}}

Run the script: cuda-install-samples-x.x.sh. It will install CUDA samples with write permissions.
After it has completed, you can go to bin/x86_64/darwin/release and run the deviceQuery project. If the CUDA toolkit is installed and configured correctly, it will display your GPU's device properties.
