    Any fix on this? Having trouble with Unity 2019.2.10 + Catalina OS + XCode 11.2

    This error should be fixed in 2019.2.x version.
    2019.3 version is still on beta test. There are so many bugs and troubles.

    PLEASE fix this bug in 2019.2.x.

    I'm very sick and tired of fixing bugs and errors everytime I update editor version.

    Changing the "Color Space" option from Gamma to Linear worked for me as well. Im on Catalina OS Unity version 2019.2.10f1

    If I change color space to Linear from Gamma it works fine.

    Any news on this? ARKit and ARFoundation in Unity rely on Metal to work so no work around there that can even allow testing.

    I can't use my MacBook either as ARKit3 only runs on iOS13 and I need Catalina to build to it.

    So all in all, unless anyone knows a way round this, I'm well and truly blocked.

    For me it got fixed by changing Graphics API from Auto (which was Metal) to OpenGLES3.
    I mean it still throws me errors with some custom shaders but, the built-in shaders work and the build succeds.
