We can take a look at supporting older platforms later when the project is more matured.
Meanwhile you could compile it Yourself.
It's all good. I'm just poking fun at the name of the binary but it doesn't seem to get across. macOS 11 and above is not "OS X". OS X is OS 10. The X is Roman numeral for the version number 10.
There's no real issue, sorry for the confusion and good luck with your project!
