I am using the default HelloPhotogrammetry app you guys made: https://developer.apple.com/documentation/realitykit/creating_a_photogrammetry_command-line_app/
My system originally did not fit the specs because of a GPU issue to run this command line. To solve this issue I bought the Apple supported eGPU Black Magic to allow the graphics issue to function. Here is the error when I run it despite the eGPU: apply_selection_policy_once: prefer use of removable GPUs (via (null):GPUSelectionPolicy->preferRemovable)
I have deduced that there needs to be this with the application running it: https://developer.apple.com/documentation/bundleresources/information_property_list/gpuselectionpolicy
I tried modifying the Terminal.plist to the updated value - but there was no luck with it. I believe the CL within Xcode needs to have the updated value -- I need help on that aspect to be able to allow the system to use the eGPU.
I did create a PropertyList within the MacOS app and added GPUSelectionPolicy with preferRemovable, and I am still having issues with the same above error. Please advice.
Also -- to note, I did try to temporary turn off the Prefer External GPU within Terminal -- and it was doing the processing of the Photogrammetry but it was taking awhile to process (>30 mins plus.) I ended up killing that task. I did have a look at Activity Monitor and I did see that my internal GPU was being used, not my eGPU which is what I am trying to use. Previously -- when I did not have the eGPU plugged in - I would be getting an error saying that my specs did not meet criteria, so it was interesting to see that it assumed my Mac had criteria (which it technically did) it just did processing on the less powerful GPU.
