Is there currently a working way of getting OSX up and running?

That flake is doing something very very weird. It has it inputs.osx-kvm.url = "path:./"; and inputs.osx-kvm.flake = false;. I believe relative paths like that worked in some Nix versions but I don’t think they do anymore. And either way, it’s completely silly. The self argument to outputs already represents this flake and can be used the way they’re using their osx-kvm input. Or just the ./. literal.

Also, just look at flake.nix. It’s not really doing anything significant. You may be better off just skipping this entirely.
