Zwift crashes or screen freezes every time I use it on my IMac

I have an iMac and every time I use zwift it either crashes or the screen just freezes.  Im using OS X El Capitan version 10.11.3 and have the NVIDIA GeForce GT 650M 512 MB graphics card, is there an issue with Swift and the operating system?

Hi Lee,

Make sure you have the latest Nvidia drivers for 10.11.3. They have been known to crash on 3d applications:

Hi Lee,

I have the same problem.

Did it work?


Hi Marc-Antoine


Yeah it worked a treat, no crashes at all now!



I downloaded the NVIDIA driver and re-opened Zwift and it froze again. Any ideas as to what I can try to get it fixed?
