Trellis, Bedrock, and Sage development on macOS 10.13+ is supported by several libraries and software packages.


Trellis, Bedrock, and Sage development on macOS relies on several libraries and software packages. This guide will show you how to install and configure each of these recommended packages on your computer. This guide assumes basic knowledge of command line and terminal usage.

Xcode Command Line Tools

Install Xcode Command Line Tools using the built-in command:

$ xcode-select --install


Git is automatically installed as part of the Xcode Command Line tools. Configure Git with your user information:

$ git config --global "Your Name"
$ git config --global ""


Install Homebrew from the instructions at, or with the following command:

$ /bin/bash -c "$(curl -fsSL"


Install Composer from Homebrew:

$ brew install composer

SSH keys

Create SSH key

Trellis and GitHub both use SSH keys to communicate securely without the need to type a username and password each time. Create your SSH key and add them to your macOS Keychain:

$ ssh-keygen -t ed25519 -C ""

For more details on generating SSH keys, see GitHub's excellent documentation.

Add your SSH key to the ssh-agent

Modify your ~/.ssh/config file to automatically load keys into the ssh-agent and store passphrases in your keychain.

Edit your ~/.ssh/config file and add the following lines:

Host *
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_ed25519

Working with Sage

Sage relies on a few build tools to manage dependencies and build assets. Install these tools:


Install nvm from the instructions at, or with the following command:

$ curl -o- | bash


Install the latest Node.js LTS release from nvm:

$ nvm install --lts


Install yarn:

$ npm install --global yarn

Working with Trellis

Trellis relies on a few additional software packages to function. Install these packages:


We recommend installing Vagrant through their official installers: Vagrant downloads

We don't recommend Homebrew for two reasons:

  1. brew automatically upgrades packages now by default which can cause issues
  2. it's very hard to downgrade to an older specific version of Vagrant if need be

If you really want to use Homebrew to manage Vagrant, then run the following:

$ brew install vagrant

Vagrant Providers

VirtualBox (Intel Macs)

Download and install the "OS X Hosts" version of VirtualBox from

Parallels (Apple Silicon (M1) Macs)

See our Vagrant docs for details.

Trellis CLI

Install Trellis CLI from Homebrew.

brew install roots/tap/trellis-cli


For macOS Catalina or later, you will have to grant full disk access to /sbin/nfsd.

  1. Navigate to System PreferencesSecurity & PrivacyPrivacyFull Disk Access
  2. Click +
  3. Press Command Shift G at the same time.
  4. Enter the /sbin directory.
