Docker Desktop for Mac is the Community version of Docker for Mac.You can download Docker Desktop for Mac from Docker Hub.

By downloading Docker Desktop, you agree to the terms of the Docker Software End User License Agreement and the Docker Data Processing Agreement.

What to know before you install

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.

System requirements

Your Mac must meet the following requirements to successfully install Docker Desktop:

Mac hardware must be a 2010 or a 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
If your Mac supports the Hypervisor framework, the command prints kern.hv_support: 1.
macOS must be version 10.14 or newer. That is, Mojave or Catalina. 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. Docker Desktop currently supports macOS Mojave and macOS Catalina.
As new major versions of macOS are made generally available, Docker stops supporting the oldest version and support the newest version of macOS.
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.

What’s included in the installer

The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Notary, Kubernetes, and Credential Helper.

Install and run Docker Desktop on Mac

Double-click Docker.dmg to open the installer, then drag the Docker icon to the Applications folder.
Double-click Docker.app in the Applications folder to start Docker. (In the example below, the Applications folder is in “grid” view mode.)
The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal.
If you’ve just installed the app, Docker Desktop launches the onboarding tutorial. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub.
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.

If you would like to rerun the tutorial, go to the Docker Desktop menu and select Learn.

Uninstall Docker Desktop

To unistall Docker Desktop from your Mac:

From the Docker menu, select Troubleshoot and then select Uninstall.
Click Uninstall to confirm your selection.

Note: Uninstalling Docker Desktop will destroy Docker containers and images local to the machine and remove the files generated by the application.

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.

Experimental features are turned on by default on Edge releases. However, when you switch from a Stable to an Edge release, you must turn on the experimental features flag to access experimental features. From the Docker Desktop menu, click Preferences > Command Line and then turn on the Enable experimental features toggle. Click Apply & Restart for the changes to take effect.

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.

Memory For Mac Os X 10.12

Classic applications in Mac OS X

When running Mac OS X, you don't need to manually set anapplication's memory size for native applications. Mac OS Xadjusts the amount of memory as the application requires more or lessspace. However, you do need to set an application's memory size ifyou are running an application in Mac OS X's Classicenvironment. To do this, follow these directions:

Determine how much memory is available and accessible to your computer. This will give you an idea how much extra memory you can allocate to the application. From the Apple menu, select About This Mac.
