I'm on PC Windows 10

I've made a player that works on PC in all browsers (chrome, firefox and edge) but can't for the life of me getting it working on my partners MAC in any browser.  Does anyone have any idea why this would be?  I'm generating an auth code, swapping for access token.. I'm able to play full tracks on PC.. it works fine, but just won't on the mac.. confused...

Is anyone able to take a look?
