That’s anachronistic. For example you’d say macOS Tahoe but Mac OS X Leopard and Mac OS 9.1.

And going back a little further, I believe it was "System 7.5.5" etc. until Mac OS 8.5 or so?

While we are on the subject it is also worth pointing out additionally:

When saying Mac OS X, it’s pronounced Mac OS ten, not Mac OS ex.
