I'm not sure it's in relation to iOS. If it was just that they wouldn't have invested in building a whole new cheese grater, nor would they bother to move the whole ecosystem to ARM when they could keep coasting on x86. There is in my opinion a level of care about macOS on its own, it's more about misguided goals and detrimental choices (Touch Bar, butterfly keyboard, etc.)
