was it ever called OS/X?

[Wowfunhappy]

It was called OS X and/or Mac OS X.

But now, not only is it not branded OS X, but it’s literally not at version 10 anymore. (The X was a roman numeral.)

It was a rhetorical question. Yes, I'm well aware it was OS X and that it was never referred to as OS/X
