MacOS compatibility issues

[AVTPJ]

I can't seem to get the latest (v2.2.3) working on Chrome (89.0.4389.114 (Official Build)) on MacOS Big Sur (11.2.3). The issue might be to do with mac os user agent reporting. I get a blank white page and this in console:

Uncaught TypeError: Cannot read property '1' of null
    at r (tour-player.js:1)
    at BrouserInfo (tour-player.js:1)
    at Object.Tour.init (tour-player.js:2)
    at (index):134

Any advice as to how to fix this?

Ok found the culprit, the user agent check doesn't take into account Mac OS 11, this is the line that breaks it:

t = /Mac OS X (10[\.\_\d]+)/.exec(navigator.userAgent)[1];
