Well, honestly, Apple already did the hard work years ago when they created OS X itself based on NextStep and used a derivative Mach microkernel. Now, Apple ofc has pushed a lot on top of that but that is platform specific so they call it a hybrid kernel but this is the true legacy of Steve Jobs. This allowed them to have a pretty tight product line using similar OSs with different user spaces and those needs. It isn't revolutionary on a technical front, that is what all that work was working towards at the colleges that developed them. But it was in fact forward thinking from a product and pricing perspective that a company would make a bold move and incorporate that when we had a lot of PC companies sticking to one arch ride or die style at the time.
