Some Assets or Tiago robot not available on Mac

[correll]

Describe the Bug
Using the TiagoLite on Mac computers makes the application crash. This has to do with some of the assets that cannot be found. Instead of steps to reproduce, here is the fix that my course staff suggested:

“After you’ve added the TiagoLite Robot and completed the basic world setup, close out of the Webots application. Open your .wbt file in a text editor and change ‘tiago_lite’ to ‘tiago_base’ in the ‘proto/meshes/’ links. Find the link that ends in ‘astra.obj’, and replace the entire link with ‘https://raw.githubusercontent.com/cyberbotics/webots/R2025a/projects/devices/orbbec/protos/meshes/astra.obj’. Save the text file, close out of the editor, and reopen the world file in Webots to continue. This change will allow your code to be run without crashing on Mac computers, whether your own or another’s during peer review.”

I'm not sure what the difference between the Mac and Windows versions is, but it only happens on Mac.

Additional context
Happy to track down more information if needed. We had now more than 3000 people taking the class on Coursera!

Best,

Did you try to use the latest nightly builds? I believe some recent fix may have addressed this problem.
