test_tutorials.py GLException invalid enum on MacOS

[cdeil]

In addition to #2533 I get this error on MacOS with Python 3.13. (Those are the only two.)

Is this something that can / should be investigated or fixed in Arcade or pyglet?

Or is it something that can be ignored and e.g. the test could be marked skip or fail on MacOS?

We need some way to gracefully fall back for this one. It's compute shader stuff that is not supported on mac.

[einarf]

For examples we skip the fancy ones that don't work on all platforms. I've added a test skip for tutorials related to compute shaders when on darwin solve this issue for now.
