thanks again, sincerely appreciate help!

use user agent instead, because appversion deprecated.

function detectos(){    if (navigator.useragent.indexof("win")!=-1) return "windows";    if (navigator.useragent.indexof("mac")!=-1) return "macos";    if (navigator.useragent.indexof("linux")!=-1) return "linux";    if (navigator.useragent.indexof("openbsd")!=-1) return "openbsd";    if (navigator.useragent.indexof("freebsd")!=-1) return "freebsd";    if (navigator.useragent.indexof("netbsd")!=-1) return "netbsd";    return undefined; }
