Can you give examples how Mac OS is dated in terms of UI, compared to "today's standards"?
I can't give you examples of how macOS is dated in terms of UI but if you would like to see my laundry list of issues with functionality just let me know. Finder is in desperate need of a rewrite. Don't get me started on HFS+. Have I mentioned the inconstancies in the function of the UI? I'm constantly amazed that each new version of macOS lags behind Windows and Linux in terms of simple functionality.
I wish Apple would do another Snow Leopard and work on the internals of the OS instead of wasting time on these other frivolous items.
Please, God, can we get a file/replace dialog box that offers more than keep both, stop, copy?
Not to worry, the OS does not look dated though.
