IIRC macOs does not support OpenGL 4.5 or Vulkan. Also there is currently no high performance Apple Hardare to do things like CUDA or other GPGPU programming. CUDA on Linux is really an easy thing to do. For Game programming tools like Unreal Engine 4 are afaik alreasy supported on Linux, which gives you multiplatform support. For graphics, music or 3D modelling windows is currently the only solution.
