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.
