seems to have some
choices where it has expectations that if
        if (!isMacOSX14 && !isMacOSXBigSur) {
then we are on some older release ..

the problem is this
            } else if (version.startsWith("11.")) {
                isMacOSXBigSur = true;
            }

I think it means 11 or later ..
