Welcome to new_mac_setup 👋

Just another automated new mac setup. Fork the repo and alter the Brew/brewfile and the SysSettings/setup.sh to your liking before running the install command.

Description

This is an automated setup for a new mac or a fresh install of mac. It is forked from the Init-blog github. You might want to fork that repo instead of this.

When running the install command, it will download the repo into a temp folder, and run install.sh. The install.sh will execute three scripts, before deleting everything it has downloaded:

1. Brew/install.sh - Installs Homebrew and all packages defined in the Brewfile
2. SysSettings/setup.sh - Configures system settings (e.g., screenshot save location, dock size, etc.)
3. SysSettings/setup_zshrc.sh - Sets up a comprehensive .zshrc with useful aliases, functions, and development shortcuts

Shell Configuration

The setup includes a comprehensive .zshrc configuration with:

• Useful aliases for development, git, system management
• Handy functions like mkcd, extract, project, cdm
• Enhanced history and git-aware prompt
• Universal package manager (ni) for seamless npm/yarn/pnpm/bun usage Check out Antfu's ni

Personal Customizations

Your existing .zshrc will be backed up to .zshrc.backup. For personal customizations that won't be overwritten by future runs, create a ~/.zshrc.local file:

# ~/.zshrc.local - Your personal customizations
alias myalias="my command"
export MY_VAR="my value"
# Add your custom functions, aliases, etc.

This file will be automatically sourced by the main .zshrc configuration.

Install

Option 1: One-line Remote Installation (Recommended)

REPO_OWNER="Bcdo"
REPO_NAME="new_mac_setup" 
curl -sSL https://raw.githubusercontent.com/"$REPO_OWNER"/"$REPO_NAME"/main/install.sh | sh -s "$REPO_OWNER" "$REPO_NAME"

Option 2: Download and Run (Alternative method)

# Download the installer
curl -sSL https://raw.githubusercontent.com/mrb/new_mac_setup/main/install.sh -o install.sh
chmod +x install.sh
./install.sh mrb new_mac_setup

Option 3: Clone Repository (For customization)

If you want to customize the setup before running:

git clone https://github.com/mrb/new_mac_setup.git
cd new_mac_setup
# Edit Brewfile and settings as desired
./install.sh mrb new_mac_setup

Requirements

• Administrator access: You'll be prompted for your password during installation
• macOS: Tested on macOS 10.15+
• Internet connection: Required for downloading Homebrew and packages

What happens during installation?

1. 🔐 Permission check - Verifies admin access (prompts for password if needed)
2. 📁 Temporary workspace - Creates ~/SystemSetupTmp
3. 📦 Package installation - Installs Homebrew and all Brewfile packages
4. ⚙️ System configuration - Applies macOS preferences and settings
5. 🐚 Shell setup - Configures .zshrc with development tools
6. 🧹 Cleanup - Removes temporary files

The entire process is color-coded and shows clear progress indicators.

🔐 Sudo Handling

The script uses advanced TTY redirection (/dev/tty) to properly handle password prompts even when run via curl | sh. You'll be prompted for your admin password once at the beginning, and the installation will proceed automatically from there.
