Apple Fitness + not working, screen turns black on Mac
I have an iPhone 13 Max Pro and a Mac computer (27 inch) that is only 1 year old. I have tried everything. Airplay and screen mirroring, to use fitness plus on my Mac - and it works for like 20 seconds and then the screen goes black every time. Why isn't this working?
