Looks interesting. Is this a binary build for mac via nix infrastructure?

Regarding the bug itself - I plan to make a prerelease tag usable by nix build with a bunch of small fixes collected from non-trivial use cases ans will definetely include VK_INSTANCE_CREATE_ENUMERATE_PORTABILITY_BIT_KHR there. Hoewer it is a bit stalled by now, so I can't promise any specific timeline

Yes, this is a Darwin executable built with Nix. I've disabled Darwin for Nixpkgs though since it's broken. I wasn't sure this is a packaging issue.

Here's the relevant PR: https://github.com/NixOS/nixpkgs/pull/296594

No need to stress it (heh), the version above already works on x86_64-linux. I'll just update this whenever you release a new version; take your time.

I also unfortunately won't have access to a Darwin machine for at least a few months.
