Docker has gained immense popularity in recent years for its ability to simplify the process of deploying and managing applications using containerization. With Docker, developers can package their applications and dependencies into containers that can run on any machine, eliminating the “it works on my machine” problem. While Docker is widely used and supported across various operating systems, in this blog post, we will focus on how to install Docker on Mac using the Terminal, providing you with a step-by-step guide to get started with Docker on your Mac machine.

The Challenge of Installing Docker on Mac Terminal
Installing Docker on Mac can be a challenge for those who are new to the concept of containerization and command-line interfaces. Navigating the Terminal and executing commands might seem intimidating at first, but this guide will break down the process into easy-to-follow steps, allowing even beginners to install Docker successfully and start using it for their projects.
Things You Should Prepare for
Before diving into the installation process, there are a few things you should prepare for to ensure a smooth and hassle-free installation of Docker on Mac.
1. macOS Version: Check the version of macOS running on your Mac. Docker has certain system requirements, and not all versions of macOS are compatible with Docker. Ensure that your macOS version is compatible with Docker by referring to the official Docker documentation or the Docker website.
2. Internet Connection: Make sure you have a stable and reliable internet connection. Docker requires an internet connection to download and install the necessary packages and dependencies.
3. Administrative Access: You will need administrative access to your Mac in order to install Docker. Ensure that you have the necessary privileges to install software on your machine.
4. Disk Space: Docker requires a certain amount of disk space to store images and containers. Make sure you have enough free disk space on your Mac to accommodate Docker and any applications you plan to run using Docker.
With these preparations in place, you are now ready to proceed with the installation of Docker on your Mac.
Method 1: Installing Docker via Docker Desktop
Docker Desktop is the easiest and recommended way to install and run Docker on Mac. It provides a user-friendly interface and simplifies the installation and management process.
1. Go to the Docker website (https://www.docker.com/products/docker-desktop) and download Docker Desktop for Mac.
2. Once the download is complete, double-click the downloaded file to start the installation process.
3. Follow the on-screen instructions and accept the license agreement to proceed with the installation.
4. Docker Desktop will prompt you to authorize the installation by entering your administrator password. Provide the necessary credentials to continue.
5. After the installation is complete, Docker Desktop will launch automatically. You will see a whale icon in the status bar, indicating that Docker is running.
6. Click on the whale icon and select “Preferences” from the menu. Here, you can configure various settings for Docker, such as resource allocation, network settings, and more.
7. Congratulations! Docker is now installed on your Mac. You can start using Docker by opening the Terminal and executing Docker commands.

Method 2: Installing Docker via Homebrew
Homebrew is a popular package manager for macOS that allows you to easily install and manage various software packages, including Docker.
1. Open the Terminal on your Mac.
2. If you haven’t installed Homebrew already, you can install it by executing the following command:
“`
/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”
“`
3. After Homebrew is installed, you can proceed with the installation of Docker by executing the following command:
“`
brew install –cask docker
“`
4. Homebrew will download and install Docker on your Mac. This process might take a few minutes, depending on your internet connection speed.
5. Once the installation is complete, you can launch Docker by searching for Docker in Spotlight or by clicking on the Docker icon in the Applications folder.
6. Docker will prompt you for administrative access to make changes. Provide the necessary credentials to continue.
7. Congratulations! Docker is now installed on your Mac. You can start using Docker by opening the Terminal and executing Docker commands.
Pros:
| Pros | Cons |
|---|---|
| Uses Homebrew’s package management | Requires additional disk space |
| Enables easy updates and management | Requires administrative access |
| Integrates with macOS ecosystem | Requires internet connection |
Method 3: Installing Docker via Docker Toolbox
If you are running an older version of macOS or have compatibility issues with Docker Desktop, you can still install and use Docker via Docker Toolbox. Docker Toolbox provides a legacy solution for older macOS versions and offers a similar experience to Docker Desktop.
1. Go to the Docker website (https://www.docker.com/products/docker-toolbox) and download Docker Toolbox for Mac.
2. Once the download is complete, double-click the downloaded file to start the installation process.
3. Follow the on-screen instructions and accept the license agreement to proceed with the installation.
4. Docker Toolbox will install several components, including Docker Machine, VirtualBox, and other dependencies. This process might take a few minutes.
5. After the installation is complete, Docker Toolbox will prompt you to authorize the installation by entering your administrator password. Provide the necessary credentials to continue.
6. Once the installation is finished, Docker Toolbox will launch automatically. You will see a Docker Quickstart Terminal window.
7. Congratulations! Docker is now installed on your Mac via Docker Toolbox. You can start using Docker by opening the Docker Quickstart Terminal and executing Docker commands.
Pros:
| Pros | Cons |
|---|---|
| Legacy solution for older macOS versions | Requires additional disk space |
| Offers similar functionality to Docker Desktop | Requires administrative access |
| Provides compatibility with VirtualBox | Requires internet connection |
Method 4: Installing Docker via Manual Installation
If you prefer a more hands-on approach or have specific requirements, you can also install Docker manually on your Mac. This method requires more technical knowledge and involves downloading and configuring Docker manually.
1. Visit the Docker website (https://www.docker.com/products/docker-desktop) and navigate to the “Mac” section.
2. Download the Docker package for Mac.
3. Once the download is complete, double-click the downloaded file to extract the Docker application.
4. Move the extracted Docker application to the Applications folder.
5. Launch Docker by searching for Docker in Spotlight or by clicking on the Docker icon in the Applications folder.
6. Docker will prompt you for administrative access to make changes. Provide the necessary credentials to continue.
7. Congratulations! Docker is now installed on your Mac. You can start using Docker by opening the Terminal and executing Docker commands.
Pros:
| Pros | Cons |
|---|---|
| Offers manual control and customization | Requires additional disk space |
| Allows for specific configurations | Requires administrative access |
| Does not rely on third-party tools | Requires internet connection for initial download |
