       error: Package ‘iterm2-3.5.14’ in /nix/store/bgl6ldj5ihbwcq8p42z3a0qzgqafgk2b-source/pkgs/by-name/it/iterm2/package.nix:44 is not available on the requested hostPlatform:
         hostPlatform.config = "x86_64-unknown-linux-gnu"

           "x86_64-darwin"

       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: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
                then pass `--impure` in order to allow use of environment variables.

       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.
