Crash on start with OsX integrated graphics (laptop) with unity build

September 12, 2019 - 11:30pm #1

Vuforia SDK Version: 8.3.8 -

Description with steps to reproduce: I have an app that is used across Pc (mac and windows) UWP and mobile. The Mac builds are not intended to use AR functionality (as obviously this will not work) however they still need to reference Vuforia libraries. I have Vuforia on delayed initialisation and no code uses vuforia in the initial scene, however the system crashes immediately and appears to indicates that Vuforia is the issue.

The app works fine on all builds aside from a certain group of Mac Laptops. The only common factor I can see is that they do not have a graphics card, instead having on-board graphics. The same build does not create problems when deployed onto an iMac (various imacs and laptops that were NOT development machines were tested)

The crash log below:

Application Specific Information:

Do the Vuforia Sample Applications show the same behavior?:

Hi,

For the first issue that you are facing on iMacs, could you please turn off Vuforia after the delayed initialization using: VuforiaBehaviour.Instance.enabled = false.

In regards to the second issue, deleting any Vuforia files from your project and afterwards re-importing the Vuforia package via the Unity PacakgeManager should resolve the issue.

Thank you.

Further to this, I have found on my system the Image Targets create an error in the editor (vuf_error 1.jpg). This system was upgraded from prior to Vuforia being an integrated package and it seems like the links to the material are confused..  Note that this also happens on a new project.
