Funny thing, "macOS" (actually "мак ос" / "мак ось") was a slang name for OS X in Russian and Ukrainian languages all this time.

  Weren't all pre OS-X versions also called Mac OS?

    Between versions 7 and 10 it was officially MacOS [VERSION], before that it was referred to as system [VERSION], as in System 6 and so on. That was not an official name, it was the version number of the file `system` and was simply the system that ran on a Mac, because there was only one. It got the official name MacOS when they allowed the selling of clones.

  We colloquially call it "Mac OS" in English too.
