Zwift crashing on Macbook Pro after approx 10min riding

Bugs and Support
#1

The app is crashing within 10 minutes after starting riding. I tried to reduce the resolution thinking that would be a GPU issue but that did not fix the problem and that was not happening before.
not only crashing, my entire computer freezes and restart.
I literally cannot use Zwift anymore:

Same issue here. This is the first time I’ve had Zwift crash on me, I thought it might be due to another app trying to run at the same time but today I just used Zwift and it happened right around the 5-10 minute mark. It doesn’t happen every time for me but has happened once, I finish a workout then if I want to do a second ride it happens about 10 mins into that ride.

Happened again this morning about 3/4 through a workout. I thought it might be related to Logitech G Hub which I uninstalled/restarted machine but had it happen again this morning.

#4

Folks you may want to check out this thread . It looks like you are on Monterey and it does not appear to be supported .

Hope this helps ,

Sara

#5

Monterey is supported. I’ve had no problems with it. Clearly some do though.
