Qt3D examples crashing on Mac OS Catalina

  • Hi,

    I have an application using Qt 5.13.1 that uses Qt3D that has started to crash on Mac OS Catalina. I also tried a few of the exampes (3d shapes) and that is also crashing.

    Does anyone have any workarounds?

    Please add information about your hardware. It might be related to your graphics card or the driver.

  • I have a similar issue. First, when opening Qt 3D Simple QML Example, I get the following:

    /Users/chris/Qt/5.12.5/clang_64/mkspecs/features/mac/default_post.prf(19): 'versionAtLeast' is not a recognized test function.
    Project WARNING: Qt requires at least version 10.13 of the platform SDK, you're building against version 10.15. Please upgrade.
    /Users/chris/Qt/5.12.5/clang_64/mkspecs/features/mac/default_post.prf(30): 'versionAtMost' is not a recognized test function.
    Project WARNING: Qt has only been tested with version 10.15 of the platform SDK, you're using 10.15.
    Project WARNING: This is an unsupported configuration. You may experience build issues, and by using
    Project WARNING: the 10.15 SDK you are opting in to new features that Qt has not been prepared for.
    Project WARNING: Please downgrade the SDK you use to build your app to version 10.15, or configure
    Project WARNING: with CONFIG+=sdk_no_version_check when running qmake to silence this warning.

    Then, when running in Debug, I get the following crash log:
