> Apple recently rebranded OSX to macOS, possibly to have a version number higher than 10 some day.

that may be, I figured it had more to be in line with tvOS, watchOS, and iOS. having somethingOS for everything except for one being OSsomething just seemed oddball enough for them to want to bring it in line.

In theory you could have 10.1234567890 for a release and retain OSX if that was the concern. I think everyone would hate them for it, but I don't think there's anything preventing it.
