Hi. On macOS the CFRunLoop was replaced with libuv because, it didn't work with glfw. We need to kick off the libuv based scheduler somewhere, right now AppKit has no scheduler active (I think AppKit kicked off a CFRunLoop automatically). I haven't gotten to it yet. #2205

If you just want to renderer run on macOS and use GLFW, you can use:

bazel run //platform/glfw:glfw_app --//:renderer=metal -- --style https://demotiles.maplibre.org/style.json
