MacOS Setup Script

A comprehensive and automated setup script for macOS, designed to install essential CLI tools, GUI applications, and customize the development environment (Zsh, oh-my-zsh, iTerm2 themes).

🚀 Overview

This script automates the tedious process of setting up a new Mac. It uses Homebrew to manage installations and includes custom helper functions to ensure a smooth, idempotent installation process (skipping already installed tools).

📦 What's Included?

CLI Tools

• Zsh: The default shell for macOS.
• Node.js: JavaScript runtime.

Helper Functions
