Homebrew is an open-source package manager for macOS that offers an easy way to install software and tolls through the command line. If you are a coder, developer, Terminal lover, or more tech-savvy than an average Mac user, you can use Homebrew to simplify software installation on your Mac.

Homebrew lets you use commands to download and install Python, Ruby, MongoDB, PHP, Git, Node.js, cask, colordiff, Nmap, and other Unix command-line utilities. In this guide, I’ll show you how to install Homebrew in macOS.

What is Homebrew on Mac?

Homebrew is an open-source package manager for Mac. You can use Homebrew to quickly find, install, and manage numerous command-line utilities and apps on your Mac. However, as per its developers, “Homebrew is a software that installs the stuff you need, but Apple didn’t.”

Homebrew offers a vast collection of software packages that are easy to install, update, and uninstall using simple Terminal commands. This makes it ideal for those who need to frequently install software without any hassle. 

With Homebrew’s command-line interface, you can quickly install several developer tools like Python or open-source apps like Chromium-based web browsers that you use daily. It’s designed to be flexible, allowing you to completely customize the installation process to suit your specific needs.

Requirements to use Homebrew on Mac

Before we deep dive into the details of installing Homebrew on Mac, let’s make sure your Mac matches the basic prerequisites for running the tool:

How to install Homebrew on macOS

Homebrew relies on several dependencies to work, so you must download each one of them. After that, you’ll have to fetch Homebrew from its GitHub repository.

Here’s the detailed five-stage process for installing Homebrew on Mac running,

1. Install Xcode from App Store

Xcode is a native Integrated Development Environment (IDE) in macOS that provides a set of tools that developers can use to create software and build complex development systems, like compilers and debuggers.

Because Homebrew relies on Xcode, you must download it from the App Store.

Note: It’s not mandatory to download Xcode to install Homebrew on a Mac. However, I still recommend doing so to ensure a smoother user experience.

1. Launch the App Store → Search for Xcode → Click Get.
   
   
2. Once the download finishes, open Xcode → Click Install.
3. Then, click Continue to complete the installation.

You might be asked to pick the platform you’d like to develop for. You must choose macOS.

2. Install command line tools for Xcode

Once you install Xcode on your Mac, you also need to install command line tools for Xcode. These tools allow your Mac to accommodate some of the Homebrew package components.

1. Open Terminal on your Mac using Launchpad or Spotlight search.
   You can also open Terminal from Finder → Applications → Utilities.
2. Type xcode-select --install in the Terminal → Hit return.
   
   
3. When a prompt appears, click Install.
   
   
4. Go through the License Agreement, then click Agree.
   
   
5. If the Mac is not connected to power, you’ll be prompted to do so. You may click Continue on Battery Power If your Mac’s battery is at 50%.
   
   
6. Once the Xcode command line tools are downloaded and installed, click Done.
   
   

3. Get Homebrew from its GitHub repository

Once you have Xcode and command line tools for Xcode ready, you can use the Terminal on your Mac to fetch Homebrew from its official GitHub repository.

While there are various Homebrew forks available out there, I’d highly recommend installing the original one to ensure maximum compatibility.

1. Open Terminal on your Mac.
2. Paste the below command into the Terminal window → Press return.
   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
3. Now, enter your Mac’s password → Then, hit return to continue.
   Note: You can’t see the password as it’s typed, but it gets recorded in the background.
   
   
4. Hit return key again to continue.
5. After running a few commands, your screen will display an Installation successful message.
   
   

4. Add Homebrew path

It’s necessary to add Homebrew to your Mac’s system path once you finish installing it. Adding Homebrew to the system path makes finding, installing, using, and managing software packages easier.

If you wish to skip this, you can still use Homebrew without doing this, you’ll need to specify Homebrew’s installation directory every time you access it via the Terminal. But why would you engage in the hassle, adding a system path makes lives easier.

1. Open Terminal on your Mac.
2. Paste the given commands one by one and hit return after each one.
   • cd /opt/homebrew/bin/
   • ls
   • PATH=$PATH:/opt/homebrew/bin
   • cd
   • touch .zshrc
   • echo export PATH=$PATH:/opt/homebrew/bin -> .zshrc
   • brew doctor
     
     
3. After entering these commands, you’ll see a message that says “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 you finish installing Homebrew on your Mac, it’s recommended that you verify if Homebrew is installed correctly. Here’s how you can do this:

1. Open Terminal on your Mac.
2. Type brew -v into the Terminal window → Press Return.
   If Homebrew is installed correctly, you’ll see a version number for it.
   
   
3. In case the last command didn’t work, type brew doctor → Hit Return.
   This command will scan the Homebrew installation for potential errors.
   
   

If you see brew -v and the Homebrew version, it means Homebrew has been installed properly. If you see the second error message, just follow the instructions and repeat the process.

How to install packages with Homebrew

This is where all the hard work comes to fruition. Once Homebrew is successfully installed on your Mac, you may follow the steps provided below to quickly find and install the apps of your choice.

1. Open Terminal on your Mac.
2. Type brew search (SearchTerm) into the Terminal window.
   You must replace (SearchTerm) with the package you’re looking for. Here, I have gone with Firefox.
   
   
3. Type brew info (PackageName) to retrieve details about a package.
   You must replace (PackageName) with the name of the package.
   
   
4. Type brew install (PackageName) into the Terminal window.
   You must replace (PackageName) with the name of the package. In my case, I’m installing the Firefox browser, so I’ve typed firefox.
   
   

After you install a software using Homebrew, it will automatically show up in the Launchpad. But If you want to access the downloaded packages (known as casks), you can find them under /opt/homebrew/caskroom in Finder.

How to uninstall packages with Homebrew

If you want to uninstall or delete specific packages or apps on your Mac, you can effortlessly do so by executing the following Homebrew command.

1. Open Terminal on your Mac.
2. Type brew list into the Terminal windows → Then press return.
   This command will list down all the apps you installed via Homebrew.
   
   
3. Type brew uninstall (PackageName) into the Terminal window.
   You must replace (PackageName) with the name of the package. In our case, we’re removing the Firefox browser, so we’ve typed Firefox.
   
   

How to turn off Homebrew analytics

Homebrew, while open-source, collects and shares analytical data with the developers to help them improve the tool. As a result, if you don’t want to contribute and share your data, you may turn off Homebrew analytics.

Remember that this step is optional, but I recommend you follow the steps given below and turn off analytics to keep your data safe and secure.

1. Open Terminal on your Mac.
2. Type brew analytics off into the Terminal window → Press Return.
   
   

How to update apps with Homebrew

Besides installing an uninstalling software package, Homebrew also offers a convenient way to keep your apps updated. Here’s how you can do this:

1. Open Terminal on your Mac.
2. Type brew outdated into the Terminal window → Then, press return.
   This command will list down all the apps that need to be updated.
3. Type brew upgrade (PackageName) into the Terminal → Press return.
   You must replace (PackageName) with the name of the package.
   
   

The steps above can help you update individual apps. However, if you want to update all apps at once, you may type brew upgrade → Then hit return.

How to update Homebrew on Mac

Like any other app on your Mac, Homebrew also receives periodic updates with new features and refinements. Here’s how you can update Homebrew:

1. Open Terminal on your Mac.

   /bin/bash -c "$(curl fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"
   
   
3. Type y in the Terminal window → Then, press Return.
   
   
4. Then, enter your Mac’s password.
