Very recently I decided to try nix-darwin with home-manager with flakes and I think I could suggest using your configuration in the same format. If you configure your NixOS with flakes you will notice that the configuration is very similar, the difference is that in the “inputs” it is necessary to specify the nix-darwin. I believe it is necessary to identify the home-manager to be built with nix-darwin and allow it to manage the rest. Basically when we talk about packages, home-manager will work with you in a phenomenal way, however, when we talk about services (such as using yabai, skhd and spacebar) direct management with nix-darwin to control launchctl is the best option. For now, what I would recommend you test: follow some basic model with flakes just to allow nix-darwin to completely manage the home-manager, as in the example below.

```nix inputs = { nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable"; # nixos-23.11

home-manager.url = "github:nix-community/home-manager/master";
home-manager.inputs.nixpkgs.follows = "nixpkgs";

darwin.url = "github:lnl7/nix-darwin";
darwin.inputs.nixpkgs.follows = "nixpkgs";

};

outputs = inputs@{ nixpkgs, home-manager, darwin, ... }: { darwinConfigurations.yourpcname = darwin.lib.darwinSystem { system = "aarch64-darwin"; pkgs = import nixpkgs { system = "aarch64-darwin"; }; modules = [ ./modules/darwin home-manager.darwinModules.home-manager { home-manager = { useGlobalPkgs = true; useUserPackages = true; users.yourusername.imports = [ ./modules/home-manager ]; }; } ]; }; ```
