Problem with OSX 10.7.5 and graphic

(Dario Costa) #1

I have a problem when I start the app.
The screen is completely wrong and I cannot do anything.

What can I do to solve the problem?

Does that only happen with Zwift? What Mac are you using? Year, date, and model.

That’s an OpenGL driver glitch.  Go to your graphics driver and update or rollback.

Here the iMac informations.

How do I can update the graphic driver? I think this is not possible…

Hi Dario,

Unfortunately, that Mac is far too old to run Zwift. We have our minimum required specifications locate don our website here:
