The devs mentioned they're not currently looking into it. The game uses Vulkan which isn't supported by MacOS, so they'd have to write a whole second renderer just for Mac.
Bummer to read that MoltenVK is too buggy to use. ISTR that neither wgpu nor Dawn use it though in favor of their own WebGPU -> Metal backends, so maybe I shouldn’t be surprised.
Vulkan is a powerful API but it’s not universally cross platform like OpenGL.
Curious that it uses Vulkan and not wgpu.
