Homebrew

Homebrew calls itself The missing package manager for macOS and is an essential tool for any developer.

Homebrew Installation

Before you can run Homebrew you need to have the Command Line Tools for Xcode installed. It include compilers and other tools that will allow you to build things from source, and if you are missing this it’s available through the App Store > Updates. You can also install it from the terminal by running the following:

sudo xcode-select --install

To install Homebrew run the following in a terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

hit Enter, and follow the steps on the screen.

Setting up your PATH

To make the Homebrew-installed programs available in your shell, you need to add your Homebrew installation location to your $PATH. This is done for you already on macOS 10.14 Mojave and newer. For older versions of macOS, do the following:

You change your path by adding /usr/local/bin to your PATH environment variable. This can be done on a per-user basis by adjusting PATH in your ~/.bash_profile. To do this, run:

echo 'PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile

(If you’re using zsh, you should do this for ~/.zshrc in addition to ~/.bash_profile.)

Alternatively, you can also insert /usr/local/bin before the first line of /etc/paths to change the global default paths order, for all users and all major shells. An admin password will be required if you modify the file.

Then, to be able to use brew you need to start a new terminal session. After that you should make sure everything is working by running:

brew doctor

If everything is good, you should see no warnings, and a message that you are “ready to brew!”.

Using Homebrew

To install a package (or Formula in Homebrew vocabulary) simply type:

brew install <formula>

To update Homebrew’s directory of formulae, run:

brew update

Note: If that command fails you can manually download the directory of formulas like this:

cd /usr/local/Homebrew/
git fetch origin
git reset --hard origin/master

To see if any of your formulas need to be updated:

brew outdated

To update a formula:

brew upgrade <formula>

Homebrew keeps older versions of formulas installed on your system, in case you want to roll back to an older version. That is rarely necessary, so you can do some cleanup to get rid of those old versions:

brew cleanup

If you want to see what formulae Homebrew would delete without actually deleting them, you can run:

brew cleanup --dry-run

To see what you have installed (with their version numbers):

brew list --versions

To search for formulas you run:

brew search <formula>

To get more information about a formula you run:

brew info <formula>

To uninstall a formula you can run:

brew uninstall <formula>

Homebrew-Cask

Homebrew-Cask extends Homebrew and allows you to install large binary files via a command-line tool. You can for example install applications like Google Chrome, Dropbox, VLC and Spectacle. No more downloading .dmg files and dragging them to your Applications folder!

To see if an app is available on Cask you can search on the official Cask website. You can also search in your terminal:

brew search <package>
