`nix develop` not working out-of-box on macOS

[weswalla]

just noting that to enter the nix shell I had to run: NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1 NIXPKGS_ALLOW_BROKEN=1 nix develop --impure

Because otherwise I would get:

error: Package ‘webkitgtk-2.40.1+abi=4.0’ in /nix/store/zjpd6dn9kza8zl3l17cwgyifsxbvi3nb-source/pkgs/development/libraries/webkitgtk/default.nix:237 is marked as broken, refusing to evaluate.

       a) To temporarily allow broken packages, you can use an environment variable
          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_BROKEN=1

        Note: For `nix shell`, `nix build`, `nix develop` or any other Nix 2.4+
        (Flake) command, `--impure` must be passed in order to read this
        environment variable.

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

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
         { allowBroken = true; }
       to ~/.config/nixpkgs/config.nix.
(use '--show-trace' to show detailed location information)

and with only NIXPKGS_ALLOW_BROKEN=1 nix develop --impure, I got:

error: Package ‘gstreamer-vaapi-1.22.2’ in /nix/store/zjpd6dn9kza8zl3l17cwgyifsxbvi3nb-source/pkgs/development/libraries/gstreamer/vaapi/default.nix:84 is not available on the requested hostPlatform:

       , refusing to evaluate.

       a) To temporarily allow packages that are unsupported for this system, you can use an environment variable
          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1

        Note: For `nix shell`, `nix build`, `nix develop` or any other Nix 2.4+
        (Flake) command, `--impure` must be passed in order to read this
        environment variable.

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

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

and then it ultimately fails to build:

when I enter the nix shell from a different repo (like notebooks) that doesn't have all this stuff:

nativeBuildInputs = with pkgs; [
                wrapGAppsHook
                perl
                pkg-config
              ];
              buildInputs = with pkgs; [
                openssl
                glib
                gtk3
                gdk-pixbuf
                webkitgtk.dev
                # Video/Audio data composition framework tools like "gst-inspect", "gst-launch" ...
                gst_all_1.gstreamer
                # Common plugins like "filesrc" to combine within e.g. gst-launch
                gst_all_1.gst-plugins-base
                # Specialized plugins separated by quality
                gst_all_1.gst-plugins-good

                gst_all_1.gst-libav

                gst_all_1.gst-vaapi
              ];

I end up getting this error running nix develop:
