How I Setup New MacBooks

I recently got a new MacBook and procrastinated setting it up for a few days. Installing apps individually and configuring your machine manually feels like a huge chore.

I also don't want to bring the trash from the previous machines with the Time Machine feature. I like to start fresh each time. If something is important enough, it'll find its way to the new machine.

After posting the following on X and doing some research, I learned about the Brewfile and macOS defaults.

Brewfile

The Brewfile allows you to install command line utilities, applications, fonts and even Visual Studio Code (and forks/variants) extensions in bulk rather than installing them one by one.

Here's my Brewfile:

# command-line utilities

brew "oven-sh/bun/bun"
brew "git"
brew "node"
brew "ffmpeg"
brew "cask"
brew "postgresql@17"
brew "zsh"
brew "zsh-autosuggestions"
brew "zsh-completions"
brew "zsh-syntax-highlighting"
brew "pnpm"
brew "npm"

# apps

cask "cursor"
cask "discord"
cask "raycast"
cask "whatsapp"
cask "warp"
cask "cleanshot"
cask "google-chrome"
cask "postman"
cask "screen-studio"
cask "imageoptim"
cask "bitwarden"
cask "docker"
cask "obs"
cask "elgato-stream-deck"
cask "elgato-camera-hub"
cask "zoom"
cask "vlc"
cask "pgadmin4"
cask "nordvpn"
cask "zed"

# fonts

cask "font-hack-nerd-font"
cask "font-menlo-for-powerline"
cask "font-jetbrains-mono"
cask "font-jetbrains-mono-nerd-font"

You can create the Brewfile in the root directory of your machine and run brew bundle once you're done with it.

The bundle command installs all the things you specified in the file.

Settings defaults

macOS also provides the defaults utility to customize the settings of your MacBooks and certain applications.

Instead of updating the settings through the UI, you can achieve the same things by using the defaults utility in the terminal.

# Enable tap-to-click for the trackpad and show the correct state in System Preferences
defaults write com.apple.AppleMultitouchTrackpad Clicking -bool true
defaults -currentHost write -g com.apple.mouse.tapBehavior -int 1

# Disable the .DS file creation
defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true
defaults write com.apple.desktopservices DSDontWriteUSBStores -bool true

# Show the path bar in the Finder
defaults write com.apple.finder "ShowPathbar" -bool "true" && killall Finder

# Show hidden files in the Finder
defaults write com.apple.finder "AppleShowAllFiles" -bool "false" && killall Finder

# Keep folders on top in Finder
defaults write com.apple.finder "_FXSortFoldersFirst" -bool "true" && killall Finder

# Keep folders on top on Desktop
defaults write com.apple.finder "_FXSortFoldersFirstOnDesktop" -bool "true" && killall Finder

# Apply the settings
/System/Library/PrivateFrameworks/SystemAdministration.framework/Resources/activateSettings -u

This is very handy because you don't have to make all the changes manually.

What's Next

• Create bash scripts to easily run the installation and commands
• Add more commands
