Screen went black when descending mountain

Hi

I just reached the top of the mountain this morning, the proper top. Starting descending and the screen went black. Everything was working, except a black screen :frowning:

Running latest zwift and a macbook pro with yosemite

 

Hi Ed,

I’m sorry to hear you’re having troubles. Let me create a support ticket so we can look at it ASAP. 

Thank you
