Segmentation fault since macOS 11 Update

[FlorianGschwandtner]

Hallo,

i'm using the Arcgis QML SDK 100.6 on MacOS with Qt 5.13.1.

Since i've updated to MacOS Big Sur (11.0.1) my Application starts up, the window where the map should be stays grey and the application terminates with a Segmentation Fault as soon as i click the window with the map.

Here is the Failure Report from macOS:

Is there a fix for this? I've reinstalled the SKD. I would prefer not to update, because then i would have to update Qt as well, which would be quite the undertaking.

Thanks for your help!

As Big Sur was just released a few weeks ago, our previous releases have not been tested and do not list Big Sur as a supported platform. Historically, most upgrades "just worked" regardless of an official support statement from us, so it is unclear at this point if Big Sur is any different or not.

Here is the 100.6 system requirements - https://developers.arcgis.com/qt/latest/qml/guide/system-requirements-100-6.htm -- High Sierra and Mojave are the 2 supported versions of macOS.

We are currently working on finishing up our 100.10 release, and we intend to fully test and support Big Sur for that release.

I have now found out that this is a problem with Qt 5.13: I can't get the samples to run with 5.13 and 100.6.

The only remedy i found is to update to Qt 5.15.2. The Arcgis Version does not matter.
