How to install Homebrew on Mac (macOS M1/M2/ M3)

Homebrew is an open-source package manager that makes it easy for Mac users to install software using the command line. If you’re a programmer, enjoy using the command line, or just want a simpler way to install software on your Mac, this piece is for you.

With Homebrew, you can install nearly any open-source program or package, including Python, Ruby, MongoDB, PHP, Git, Node.js, and even casks like Slack, VLC, and many more. In this article, I’ll walk you through the step-by-step process to install Homebrew on your Mac, along with how to use it. But before that, let’s quickly go over what Homebrew is and the installation requirements.

What is Homebrew?

Homebrew is a package manager for macOS that makes it easy to install, update, and manage applications, programming languages, and utilities on a Mac using the command line. According to its developers, Homebrew “installs the stuff you need that Apple didn’t.”

This package manager is an open-source project developed and maintained by a large community of contributors. It not only just help install apps but also handles dependencies, ensuring that all required packages are installed correctly.

While the App Store is great for installing all sorts of applications on your Mac, you won’t find most open-source software and tools—often available on GitHub—there. So, Homebrew is a piece of software used to install and manage other software packages on your Mac.

Think of it as the app store for command-line tools, libraries, and casks (GUI applications) — it makes software installation much easier. You simply have to run a command in your terminal to install the software you need and manage the app—update, uninstall, and more.

Benefits of using Homebrew

The fact is, using Homebrew makes installing software a lot easier, especially if you’re comfortable running a few simple commands—that’s the main advantage of using it on a Mac. Here are all the main benefits of using Homebrew on Mac:

• Easy Installation: Homebrew makes installing software super simple—just run a command and you’re done. No need for manual downloads or setups.
• Huge Software Selection: You can install a wide range of open-source tools, programming languages, libraries, and even GUI apps (casks). It allows you access to a huge repository of software not readily available through the Apps Store.
• Automatic Dependency Handling: Homebrew takes care of all the required libraries and tools for you, so everything you install works without a hitch.
• Quick Updates and Uninstalls: It makes updating or removing software fast and hassle-free with just a command, keeping your system organized and up-to-date.
• Strong Community Support: Homebrew is open-source and backed by a huge community, meaning you get frequent updates and access to tons of software.

6. Once the Xcode command line tools are downloaded and installed, click Done.
   
   

3. Install Homebrew from its GitHub repository

Once you have Command Line Tools for Xcode ready, you can use the Terminal on your Mac to fetch Homebrew from its official GitHub repository. Here are the steps to follow:

2. Go to the official Homebrew website and copy the installation command provided under “Install Homebrew”:
   
   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
   
   
3. In the Terminal window, paste the command and press Return.
4. When prompted, enter your Mac’s password and press Return to proceed. Keep in mind that you won’t see anything appear on your screen as you type your password.

After installing Homebrew, you may need to add it to your shell’s PATH. This makes finding, installing, using, and managing software packages easier.

If you choose to skip this step, you can still use Homebrew, but you’ll have to specify its installation directory every time you access it in the Terminal. To save yourself some hassle, here’s how to add Homebrew to you PATH;

1. Open the Terminal app on your Mac.
2. Paste the following commands one by one, pressing Return after each:
   • cd /opt/homebrew/bin/
   • ls
   • PATH=$PATH:/opt/homebrew/bin
   • cd
   • touch .zshrc
   • echo 'export PATH=$PATH:/opt/homebrew/bin' >> .zshrc
     
     
3. After updating the PATH, run the following command to ensure everything is working properly:
   • brew doctor
4. If everything is set up correctly, you should see the message: “Your system is ready to brew.”

That’s it! You can verify if Homebrew has been installed correctly and get moving!

5. Verify if Homebrew is installed correctly

After installing Homebrew on your Mac, it’s a good idea to verify that the installation was successful. Here’s how to do that:

1. Open the Terminal app on your Mac.
2. Type brew --version in the Terminal window and press Return.
   
   
3. If Homebrew is installed correctly, you’ll see its version number displayed.
4. If the command doesn’t work, type brew doctor and hit Return. This command will check your Homebrew installation for any potential issues.
