Can Unity provide instructions for how to patch this in older versions such as 2017?
Upgrading is not always possible and it looks like some people here have a work-around.

Hi ! When building from MacOS (BigSur, m1 SoC) to a wegGL build in 2020.3.x, the said build ain't working. With the same parameters, no issue when building from w10.
This make me unable to "fully" WFH with my mbp. -

Having issues off and on, today I hit it again with 2021.1.4 while older 2021.1 versions were able to build. It's really frustrating.

Fixed in 2019.4.18f1 (didn't check versions before that)
Did notice 99% of the unity webgl games on itch.io don't run on Big Sur Chrome because of this Unity bug.
Filed a bug on Chrome just incase they want to revisit the userAgent string to work around unity's bug

Why is it acceptable that this is broken for almost two months for the LTS version?

We did kind of a small hack to fix it. Basically we overwrite the userAgent to a working version and set it back:
/**
* Overwriting the UnityLoader to fix a bug in their regular expression for Mac OS X 11+
*/
(function() {
if (!window["UnityLoader"]) return;// Get OS Version (Intel Mac OS X 11_0)
var os_version = /Mac OS X ([\.\_\d]+)/.exec(navigator.userAgent);
if (os_version && os_version[1]) {
// Extract "10_15_7" -> 10
os_version = parseInt(os_version[1].split("_")[0], 10);
}// The issue occured with Mac OS X 11+
if (os_version && os_version >= 11) {UnityLoader.OriginalSystemInfo = UnityLoader.SystemInfo;
UnityLoader.SystemInfo = function() {
try {
return UnityLoader.OriginalSystemInfo();
} catch () {
var original_ua = navigator.userAgent;// Overwrite the user agent with a one we know was working:
var valid_ua = navigator.userAgent.replace(/Mac OS X ([\.\_\d]+)/, "Mac OS X 10_15_7");
window.navigator.__defineGetter__('userAgent', function () {
return valid_ua;
});var result = UnityLoader.OriginalSystemInfo();
// Restore original userAgent
window.navigator.__defineGetter__('userAgent', function () {
return original_ua;
});return result;
}
};
}})();
Obviously this script has to get loaded after the UnityLoader.js

Will you support it in the next 2019 patch as well?
Unfortunately we have games which were developed in older versions then 2021.
