macOS has way too many products but far too few features. In terms of feature-completeness, it's already crippled. What OS features can macOS afford to lose?
I would say it's less about losing and more about focus. Identify the lines of business you don't want to be in and sell those features to a third party who can then bundle them for $1/$10/$20. A $2T company just doesn't care, but I would bet that those excised features would be good enough for a smaller software house.
