Introduction

This repository contains my personal dotfiles for setting up a new macOS machine. It includes configurations for development tools, system preferences, and a streamlined setup process.

Features

• Shell & Package Management

  • Oh My Zsh for enhanced shell experience
  • Homebrew for package management with Brewfile for all apps and binaries
  • zsh-autosuggestions for shell suggestions

• Development Environment

  • Latest Node.js LTS version via nvm
  • PHP development tools:
    • phpcs & phpcbf configured for Drupal coding standards
    • composer-diff for comparing Composer dependencies
  • DDEV development environment setup with mkcert
  • Git configuration with global settings and gitignore
  • Neovim as terminal editor
  • Lazygit for terminal git UI
  • pnpm for fast Node.js package management

• Apps & Tools

  • Ghostty terminal
  • Bruno API client
  • Claude Code AI CLI
  • DDEV local development environment
  • Ollama for running local LLMs

• System Configuration

  • Custom macOS defaults for optimal development experience
  • Project directory structure setup
  • Automatic repository cloning for personal projects

Installation

1. Prerequisites

   • Ensure you have SSH keys set up and added to GitHub
   • Have a fresh macOS installation ready

2. Setup Process

   # Clone the repository
   git clone --recursive git@github.com:abhisekmazumdar/dotfiles.git ~/.dotfiles
   
   # Run the installation script
   cd ~/.dotfiles && ./fresh.sh

The installation script will:

• Install and configure Oh My Zsh
• Set up Homebrew and install all specified packages
• Create symbolic links for configuration files
• Set up development tools and environments
• Configure system preferences
• Optionally clone your GitHub repositories

Directory Structure

• brew/ - Homebrew bundle configuration (Brewfile)
• git/ - Git configuration files (.gitconfig, .gitignore_global)
• macos/ - macOS system preferences
• zsh/ - Zsh configuration files (.zshrc, aliases.zsh, path.zsh)
• fresh.sh - Main installation script
• clone.sh - Repository cloning script

CI & Verification

The CI pipeline runs on every push and pull request against a fresh macOS (Apple Silicon) GitHub Actions runner. It calls fresh.sh directly — the same script you'd run on a new Mac — with two CI-specific adjustments:

What CI skips	Why
GUI cask apps (Arc, PhpStorm, Slack…)	No display server on headless runners
macOS system preferences (.macos)	No need to set hostname/Dock/Finder on a runner
Interactive clone prompt	No user to answer y/n
source ~/.zshrc	Runner uses bash; sourcing a zsh config would fail

Everything else runs identically to a real Mac: Homebrew, Oh My Zsh, symlinks, nvm + Node LTS, phpcs, phpcbf, composer-diff.

Last tested locally

After running ./fresh.sh on your Mac, update the table above and open a PR.

Optional: Cleaning Your Old Mac

After setting up your new Mac, you may want to clean install your old machine. Follow Apple's official guide for erasing and reinstalling macOS. Remember to backup your data first!
