I don’t follow that Apple doesn’t want people to play games on Macs. Of course they do. But the question becomes “Do developers want to make games for the Mac?” And the answer has been “no” most of the time because it’s expensive to develop for a small platform. You won’t get a lot of sales out of it. Apple just recently released a porting toolkit to make it easier to get Windows games running on macOS. Frankly, not unlike the work that Valve has put in to running Windows games on Steam. In typical Apple fashion, they want you to do things their way. Instead of bolstering OpenGL (for instance) or Vulkan they developed Metal. Apple does want games on the Mac, but games are a bonus for Apple at this point. They’re not going to define the platform, or drive adoption.
