macOS Monterey: Setting up a Mac for Development
Last Updated: 1/28/2022
The setup assistant will launch once you turn the computer on. Enter your language, time zone, Apple ID, and so on. The first thing you should do is update macOS to get the latest security updates and patches.
- Install apps via Homebrew
- Shell setup with zsh
- Set up Node via nvm
- Set up git config
- Set up SSH keys and config
- macOS settings
- Application settings
Install the Homebrew package manager. This will allow you to install almost any app from the command line.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Make sure everything is up to date.
Note: On the M1 install, there will be a few errors at the end, you'll have to run the commands to add to path, then run
brew doctorand run the commands listed.
Here are a few shell programs I always use:
Here are some the applications I always install (
cask flag in Homebrew):
Do not install Node.js through Homebrew. Use nvm (below).
|Visual Studio Code||text editor|
|Google Chrome||web browser|
## Shell Programs brew install \ git \ bat \ exa \ tldr \ fzf && # GUI programs brew install --cask \ visual-studio-code \ google-chrome \ firefox \ rectangle \ iterm2 \ docker \ discord \ slack \ spotify \ postgres \ postico \ bear \ todoist \
Catalina comes with zsh as the default shell. Install Oh My Zsh for sensible defaults.
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
I add a few alises.
alias cat="bat" alias ls="exa"
Use Node Version Manager (nvm) to install Node.js. This allows you to easily switch between Node versions, which is essential.
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
Install the latest version.
nvm install node
Restart terminal and run the final command.
nvm use node
Confirm that you are using the latest version of Node and npm.
node -v && npm -v
For later, here's how to update nvm.
nvm install node --reinstall-packages-from=node
Here's how to switch to another version and use it.
nvm install xx.xx
nvm use xx.xx
And to set the default:
nvm alias default xx.xx
The first thing you should do with Git is set your global configuration.
Input your config and create some aliases.
[user] name = Firstname Lastname email = firstname.lastname@example.org [github] user = username [alias] a = add ca = commit -a cam = commit -am cm = commit -m s = status p = push pom = push origin master puom = pull origin master cob = checkout -b co = checkout fp = fetch --prune --all l = log --oneline --decorate --graph lall = log --oneline --decorate --graph --all ls = log --oneline --decorate --graph --stat lt = log --graph --decorate --pretty=format:'%C(yellow)%h%Creset%C(auto)%d%Creset %s %Cgreen(%cr) %C(bold blue)%an%Creset'
With the above aliases, I can run
git s instead of
git status, for example. The less I have to type, the happier I am.
Generate SSH key
You can generate an SSH key to distribute.
ssh-keygen -t ed25519 -C "email@example.com"
eval "$(ssh-agent -s)"
ssh-add -K ~/.ssh/id_rsa
Simplify the process of SSHing into other boxes with your SSH config file. Create
~/.ssh/config if it does not already exist.
Add the following contents, changing the variables for any hosts that you connect to. Using the below will be the same as running
ssh -i ~/.ssh/key.pem firstname.lastname@example.org.
Host * AddKeysToAgent yes UseKeychain yes IdentityFile ~/.ssh/id_ed25519 Host myssh HostName example.com User user IdentityFile ~/.ssh/key.pem
Now just run the alias to connect.
I don't like a lot of the Apple defaults so here are the things I always change.
To get the Home folder in the finder, press
CMD + SHIFT + H and drag the home folder to the sidebar.
- Set Dark mode

- Automatically hide and show Dock
- Show indicators for open applications
- Key Repeat -> Fast

Security and Privacy
- Allow apps downloaded from App Store and identified developers
- Turn FileVault On (makes sure SSD is securely encrypted)
- Change computer name
- Make sure all file sharing is disabled
Users & Groups

A few more commands to change some defaults.
# Show Library folder chflags nohidden ~/Library # Show hidden files defaults write com.apple.finder AppleShowAllFiles YES # Show path bar defaults write com.apple.finder ShowPathbar -bool true # Show status bar defaults write com.apple.finder ShowStatusBar -bool true # Prevent left and right swipe through history in Chrome defaults write com.google.Chrome AppleEnableSwipeNavigateWithScrolls -bool false

That sums it up for my current preferences on setting up a MacBook Pro. I hope it helped speed up your process or gave you ideas for the next time you're setting one up.
