Do the wgpu examples run?
Specifically, the boids example uses compute shaders.

Additionally, does the bevy compute_shader_game_of_life example run?

It is probably also worth asking on the wgpu matrix about this.

Unfortunately, the panic line corresponds to the very first shader; that suggests that your metal compiler does not support compute shaders at all.

[bitec0de]

wgpu boids doesn't run, no: zsh: segmentation fault cargo run --example boids

EDIT: nor compute_shader_game_of_life, it just outputs:

sorry, this wasn't your fault; i'd assumed after having just upgraded the OS the graphics drivers would all work

shame wgpu won't work with 2015 hardware, i hope Piet remains a rendering option
