I suspect that you haven’t tried very hard to get by on macos using primarily the keyboard. It used to be troublesome, but I’ve been doing it for years with very few issues. Of course, if you have an OS that works for you, keep using it, by all means! For file management, I find it superior, but I prefer cli tools for file management anyway. I myself got into Mac OS X (as it was called at the time) because I needed both ready access to tools like MS Office, and a usable cli.
