Check system requirements

Trying bevy on a 2015 MacBook Air, half the examples work, and half of them* error with Failed to create pipeline: Unsupported usage: Implementation specific error occurred. Digging slightly deeper, a similar wgpu example reports the issue is missing SAMPLED_TEXTURE_BINDING_ARRAY capability - is that information available to bevy, to be reported instead of the opaque "implementation specific error"? (And is this in fact an issue of outdated hardware?)

What version of macOS? I had a mid 2014 macbook pro that supported metal 2 well enough that wgpu worked. You do need to be on a newer version of macOS(High Sierra or later).

Ah, I appear to be on regular Low Sierra, 10.12.4. If I update it what all should I expect to break? Is it even possible to update only one OS version at this point?

I'm not sure if you can update to an older version instead of latest. If you have any 32 bit applications you wont be able to run those anymore is probably the biggest thing.
