Homebrew is an open-source package manager for macOS that simplifies the installation and management of software. It is especially helpful for developers, as it provides a convenient way to install various development tools and libraries. This article will guide you through the process of installing Homebrew on your macOS system step-by-step.
Prerequisites
Before installing Homebrew, ensure that your macOS system is up-to-date and you have administrative privileges. It is also necessary to have Apple’s Xcode Command Line Tools installed, as Homebrew relies on them for compiling software.
Step 1: Install Xcode Command Line Tools
To install the Xcode Command Line Tools, open Terminal and enter the following command:
xcode-select --install
A dialog box will appear, prompting you to confirm the installation. Click “Install” to begin the process. Once the installation is complete, you can proceed with the Homebrew installation.
Step 2: Install Homebrew
The Homebrew installation script is available on the project’s GitHub repository. To download it, enter the following command in Terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
The script will now perform a series of checks to verify that your system is compatible with Homebrew. If everything is in order, you will be prompted to enter your password and confirm the installation.

Upon successful installation, Homebrew will provide you with some useful information, including the installation path and how to get started with Homebrew commands.
Step 3: Configure Homebrew
3.1. Add Homebrew to Your PATH
To use Homebrew commands without specifying the full path, you need to add Homebrew to your system’s PATH variable. Open your shell configuration file (e.g., ~/.zshrc for Zsh or ~/.bash_profile for Bash) in your preferred text editor:
nano ~/.zshrc
Add the following line to the file:
1 | export PATH="/usr/local/bin:$PATH" |
Save and close the file. Restart your Terminal or run source ~/.zshrc
(or source ~/.bash_profile
for Bash) to apply the changes.
3.2. Check Your Homebrew Installation
To verify that Homebrew is installed correctly and working, run the following command:
brew doctor
If you see “Your system is ready to brew,” your Homebrew installation is successful.
Step 4: Using Homebrew
Homebrew is used for installing, updating and removing packages from your system.
4.1. Update Homebrew
Before installing new packages, it’s a good practice to update Homebrew to ensure you have access to the latest package versions. To update Homebrew, run:
brew update
4.2. Install Packages
To install a package using Homebrew, use the brew install command followed by the package name:
brew install packageName
For example, to install the Git version control system, run:
brew install git
4.3. Uninstall Packages
To uninstall a package, use the brew uninstall command followed by the package name:
brew uninstall packageName
4.4. Search for Packages
To search for available packages, use the brew search command:
brew search searchTerm
4.5. List Installed Packages
To list all installed packages, run:
brew list
Conclusion
You have successfully installed Homebrew on your macOS system. This package manager will simplify your software installation and management, making it easier for you to maintain your development environment and explore new tools. As you work with Homebrew, remember to keep it up-to-date and periodically run brew doctor to check for potential issues. By doing so, you can ensure that your system remains efficient and secure.
In addition to the basic commands discussed in this article, Homebrew offers many other features and options. For more information and to explore further, visit the official Homebrew documentation at https://docs.brew.sh/.
With Homebrew installed, you can now effortlessly install various development tools, libraries, and services such as Node.js, Python, MySQL, and more. By leveraging Homebrew’s capabilities, you can streamline your development workflow and enhance your productivity as a developer on macOS.
