OSX should changed to macOS

[18o]

current the latest version of operating system on mac is 12 which is called macOS not OSX, since version 11 OSX has been discarded

Since more versions of OSX 10 are supported than the 2 that are 11 and 12, OSX would still be more apt. And if you look at bit more you would notice that the binaries for 11 and 12 are named macos including the binaries from the "Continuous build Macos".

If apple have decided to also retroactively rename the older versions to macos, I can't say I really care. Anyone confused to what OSX would mean should be able to by deduction decipher it from the text in the readme where both OSX and Macos are mentioned.
