macOS would suck if it ran on every kind of hardware. It's because it's all so tightly controlled that it works so great.

Windows is not inherently bad. But the premise of it working everywhere means some trade-offs are made. Same for Android.

Mac OS already runs on lots of different hardware. Just look at the list of compatible hardware for building a Hackintosh. Graphics cards aside, there's a lot of compatible components.
