How To Install Docker Desktop On Mac

Docker is a tool that can be used to set up different environments having its own set of applications in a container without installing the applications on the main system. This makes it easy to develop multiple projects on the same system without installing the project-specific applications on the system. Docker can be used to run applications in lightweight containers without interfering with the system configurations and software installed on the system.

This tutorial provides all the steps required to install Docker Desktop on macOS Catalina on Intel Chip. The steps should be the same on other versions of macOS including Big Sur.

We can install Docker Desktop for macOS on Mojave, Catalina, or Big Sur. The system must have at least 4GB of RAM. Also, VirtualBox prior to version 4.3.30 must not be installed on the system.

Download Docker Desktop for macOS

In this step, we will download the Docker Desktop DMG for macOS from the official website as shown in Fig 1. It includes Docker Engine, Docker CLI Client, Docker Compose, Docker Content Trust, Kubernetes, and Credential Helper.
