I made a macOS desktop app to manage Nix-Darwin and Home Manager

- **Nix** is a purely functional package manager and build system; unlike traditional package managers (Homebrew, apt), it builds packages in isolated environments and can manage entire system configurations declaratively (i.e., you define your entire system setup in a config file, not by running interactive commands). <br>- **nix-darwin** is the Nix-based equivalent of "dotfiles" for macOS — it lets you declaratively configure macOS system settings (Dock, defaults, services) using Nix, similar to what NixOS does for Linux.<br>- **Home Manager** is a Nix-based tool for managing user-level configuration — installed packages, shell settings, dotfiles, and so on — inside your home directory, independent of the OS-level Nix config.<br>- **The project (nixmac)** is a native macOS GUI app (Swift/SwiftUI) that provides a point-and-click interface for configuring nix-darwin and Home Manager, lowering the barrier for people who want the power of Nix but don't want to hand-write the configuration files (or learn the Nix language). It competes conceptually with projects like **nix-gui** — though that aims at NixOS, not macOS specifically.
