You're setting the bar extremely low. MacOS is explicitly not supposed to run on any other hardware configurations than exactly those sold by Apple. It was never it's intended behaviour. There is nothing to be ahead of, MacOS didn't even bother to get out of bed on race day.

That's my entire point. We frequently assume that most hardware "just works" because it follows some specification or another. It's not until you run into a system that just flat out blows up when it runs into unexpected hardware that the work that Windows and Linux developers do becomes apparent.
