Generally I stay away from Apple products or topics. The only reason I decided to comment was that I am forced to use Mac in my current work and after several stints I understood I was not going to get used to it. If people use it and like it, I don't mind. For me, it's just not intuitive; for instance, I wouldn't have thought of looking for this setting, let alone under accessibility options.
