I think it's tough when it's an annual thing. One comment in this thread is, "Do you have Oreo?" "Don't know, let me check", but in Settings/About/Version it would show "7.0". Then I would need to Google what number Oreo is.

I use macOS and only started having that problem after they went to annual releases (or maybe I started making desktop maintenance less of a priority?) even though it does show both Mojave and 10.14 in the About.

Although, I do wish there was more whimsy in tech.
