Installing and Using Homebrew on macOS

Posted December 20, 2024 By Chandler Thompson

So, you’ve got your shiny Mac running macOS, and you’re ready to turn it into a developer’s paradise. Enter Homebrew—the package manager that makes managing software on macOS a breeze. This guide will walk you through why you should use Homebrew, how to install it, and some tips and tricks to get the most out of it.

Why Use Homebrew on macOS?

Homebrew is a free and open-source package manager designed to simplify the installation of software on macOS (and Linux). Think of it as an App Store for the command line, where you can install apps and developer tools with a single command.

Pros and Cons

Pros

Simplicity: Installing, updating, and managing software is a breeze.
Customizability: Access to a vast library of packages, from productivity tools to quirky utilities.
Community-driven: Regular updates and new packages added by a thriving open-source community.
Dependency management: Automatically installs and manages dependencies for you.
Uninstall-friendly: Removes software cleanly without leaving orphan files.
Auto-updating casks: Homebrew automatically updates both command-line tools and applications (casks) installed through it, ensuring you always have the latest versions.

Cons

Command-line knowledge required: A basic understanding of the terminal is needed (but don’t worry, you’ll learn fast!).
Potential conflicts: Some packages may clash with system-provided software (though rare and usually fixable).

Installing Homebrew

Special Note: Homebrew requires the Xcode Command Line Tools (CLT) to work properly. Historically, these were installed using the command xcode-select --install. However, Homebrew will now automatically install Xcode CLT during its setup process (if they are not already installed). I prefer to install with Homebrew, but if you prefer to manage this manually, you can still run xcode-select --install before installing Homebrew.

Getting Homebrew set up is as easy as following the instructions on the Homebrew website.

Open your terminal (Cmd + Space, type “Terminal”).

Paste the following command to install Homebrew:

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

Follow the on-screen instructions to complete the installation.

💡 Pro Tip: After installation, run brew doctor to ensure everything is configured correctly.

Homebrew’s commands are designed to be straightforward. Here are the essentials:

Search for a package:
