> MacOS 10 wasn't rebranded from OS X until 2016

X means 10 in latin.

Look at old MacOS X 10.3 books, X always stood for 10.

Even your mac will say 10 if you get to speak out Mac OS X. But I have had many a people insist it was not pronounced as Mac OS 10, but as Mac OS X.

I could understand the confusion.
