Package ‘mapmap-0.5.0’ in /Users/graham/nix-borg/repo/38dca4e3aa6bca43ea96d2fcc04e8229/builder/grahamc-ndnd/pkgs/applications/video/mapmap/default.nix:56 is not supported on ‘x86_64-darwin’, refusing to evaluate.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowBroken = true; }
to ~/.config/nixpkgs/config.nix.
