What to know before you install
README FIRST for Docker Toolbox and Docker Machine users
If you are already running Docker on your machine, first readDocker Desktop for Mac vs. Docker Toolbox to understand theimpact of this installation on your existing setup, how to set your environmentfor Docker Desktop on Mac, and how the two products can coexist.

Relationship to Docker Machine: Installing Docker Desktop on Mac does not affect machines you created with Docker Machine. You have the option to copy containers and images from your local default
machine (if one exists) to the Docker Desktop HyperKit VM. Whenyou are running Docker Desktop, you do not need Docker Machine nodes running locally (or anywhere else). With Docker Desktop, you have a new, nativevirtualization system running (HyperKit) which takes the place of theVirtualBox system. To learn more, see Docker Desktop for Mac vs. Docker Toolbox.
System requirements
Your Mac must meet the following requirements to successfully install Docker Desktop:
Mac hardware must be a 2010 or newer model, with Intel’s hardware support for memory management unit (MMU) virtualization, including Extended Page Tables (EPT) and Unrestricted Mode. You can check to see if your machine has this support by running the following command in a terminal:
sysctl kern.hv_support
macOS must be version 10.13 or newer. We recommend upgrading to the latest version of macOS.
If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.
Note: Docker supports Docker Desktop on the most recent versions of macOS. That is, the current release of macOS and the previous two releases. As new major versions of macOS are made generally available, Docker will stop supporting the oldest version and support the newest version of macOS (in addition to the previous two releases).
At least 4 GB of RAM.
VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.
Note: If your system does not satisfy these requirements, you can install Docker Toolbox, which uses Oracle VirtualBox instead of HyperKit.
What’s included in the installer
The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Docker Machine, and Kitematic.
Install and run Docker Desktop on Mac

Dark Mind Games A project dedicated to the youth of America trying to explode through the sheild of misfortune. Time for a change. Sunday, September 29, 2002. Welcome to the first day of what is to be a yearlong project throughout California. More information will be posted in the following days.
You are prompted to authorize
Docker.app
with your system password after you launch it. Privileged access is needed to install networking components and links to the Docker apps.The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal.
If you just installed the app, you also get a message with suggested next steps and a link to the documentation. Click the Docker menu () in the status bar to dismiss this pop-up notification.
Click the Docker menu () to seePreferences and other options.
Select About Docker to verify that you have the latest version.
Congratulations! You are now successfully running Docker Desktop.
Switch between Stable and Edge versions
Docker Desktop allows you to switch between Stable and Edge releases. However, you can only have one version of Docker Desktop installed at a time. Switching between Stable and Edge versions can destabilize your development environment, particularly in cases where you switch from a newer (Edge) channel to an older (Stable) channel.
For example, containers created with a newer Edge version of Docker Desktop maynot work after you switch back to Stable because they may have been createdusing Edge features that aren’t in Stable yet. Keep this in mind asyou create and work with Edge containers, perhaps in the spirit of a playgroundspace where you are prepared to troubleshoot or start over.
To safely switch between Edge and Stable versions, ensure you save images and export the containers you need, then uninstall the current version before installing another. For more information, see the section Save and Restore data below.
Save and restore data
You can use the following procedure to save and restore images and container data. For example, if you want to switch between Edge and Stable, or to reset your VM disk:
Use
docker save -o images.tar image1 [image2 ..]
to save any images you want to keep. See save in the Docker Engine command line reference.Use
docker export -o myContainner1.tar container1
to export containers you want to keep. See export in the Docker Engine command line reference.Uninstall the current version of Docker Desktop and install a different version (Stable or Edge), or reset your VM disk.
Use
docker load -i images.tar
to reload previously saved images. See load in the Docker Engine.Use
docker import -i myContainer1.tar
to create a filesystem image corresponding to the previously exported containers. See import in the Docker Engine.
