    If I export QSG_INFO=1 and QT_OPENGL=software I see that it always uses the nVidia driver (and hardware.) I am trying to reproduce a problem on macOS VMs where the only driver is the Apple software OpenGL driver.

    It appears that on macOS/OSX Qt doesn't support QT_OPENGL as an environment variable like it does on Linux/Windows - but I hope I'm just doing it wrong ;).

    Thanks!

      Hi,

      I don’t think you are. AFAIK, there’s only one backend for macOS and that’s desktop OpenGL.

      It’s likely one level below that Apple does its magic.

        @SGaist Yeah, looked through the source and that was the conclusion I came to - thanks :)

        It's not a serious problem, just an annoyance.

        Cheers,

        Hans
