macOS Nix Configuration

This repository contains the configuration for Sean’s macOS system, built using nix-darwin and home-manager, fully modularized via Nix flakes.

It manages:

• System-wide settings (defaults, packages, services)
• Homebrew (via nix-darwin + nix-homebrew integration)
• User environment (shell setup, dotfiles, tools) using Home Manager
• Modular split across multiple focused .nix files
