Welcome to Docker Desktop! The Docker Desktop for Mac user manual provides information on how to configure and manage your Docker Desktop settings.
For information about Docker Desktop download, system requirements, and installation instructions, see Install Docker Desktop.
Note
This page contains information about the Docker Desktop Stable release. For information about features available in Edge releases, see the Edge release notes.
Preferences
The Docker Preferences menu allows you to configure your Docker settings such as installation, updates, version channels, Docker Hub login,and more.
Choose the Docker menu > Preferences from themenu bar and configure the runtime options described below.
General
On the General tab, you can configure when to start and update Docker:
Resources
The Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources.
Advanced
On the Advanced tab, you can limit resources available to Docker.
Advanced settings are:
CPUs: By default, Docker Desktop is set to use half the number of processorsavailable on the host machine. To increase processing power, set this to ahigher number; to decrease, lower the number.
Memory: By default, Docker Desktop is set to use
2 GB runtime memory,allocated from the total available memory on your Mac. To increase the RAM, set this to a higher number. To decrease it, lower the number.
Swap: Configure swap file size as needed. The default is 1 GB.
Disk image size: Specify the size of the disk image.
Disk image location: Specify the location of the Linux volume where containers and images are stored.
You can also move the disk image to a different location. If you attempt to move a disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it.
File sharing
Use File sharing to allow local directories on the Mac to be shared with Linux containers.This is especially useful forediting source code in an IDE on the host while running and testing the code in a container.By default the
/Users , /Volume , /private , /tmp and /var/folders directory are shared. If your project is outside this directory then it must be addedto the list. Otherwise you may get Mounts denied or cannot start service errors at runtime.
File share settings are:
Tips on shared folders, permissions, and volume mounts
Proxies
Docker Desktop detects HTTP/HTTPS Proxy Settings from macOS and automaticallypropagates these to Docker. For example, if you set yourproxy settings to
http://proxy.example.com , Docker uses this proxy whenpulling containers.
Free 3d printer cad software mac. Your proxy settings, however, will not be propagated into the containers you start.If you wish to set the proxy settings for your containers, you need to defineenvironment variables for them, just like you would do on Linux, for example:
For more information on setting environment variables for running containers,see Set environment variables.
Network
You can configure Docker Desktop networking to work on a virtual private network (VPN). Specify a network address translation (NAT) prefix and subnet mask to enable Internet connectivity.
Docker Engine
The Docker Engine page allows you to configure the Docker daemon to determine how your containers run.
Type a JSON configuration file in the box to configure the daemon settings. For a full list of options, see the Docker Enginedockerd commandline reference.
Click Apply & Restart to save your settings and restart Docker Desktop.
Now Desktop App Mac IosCommand Line
On the Command Line page, you can specify whether or not to enable experimental features.
Experimental features provide early access to future product functionality.These features are intended for testing and feedback only as they may changebetween releases without warning or can be removed entirely from a futurerelease. Experimental features must not be used in production environments.Docker does not offer support for experimental features.
To enable experimental features in the Docker CLI, edit the
config.json file and set experimental to enabled.
To enable experimental features from the Docker Desktop menu, clickSettings (Preferences on macOS) > Command Line and then turn onthe Enable experimental features toggle. Click Apply & Restart.
For a list of current experimental features in the Docker CLI, see Docker CLI Experimental features.
On both Docker Desktop Edge and Stable releases, you can toggle the experimental features on and off. If you toggle the experimental features off, Docker Desktop uses the current generally available release of Docker Engine.
You can see whether you are running experimental mode at the command line. If
Experimental is true , then Docker is running in experimental mode, as shownhere. (If false , Experimental mode is off.)
Kubernetes
Docker Desktop includes a standalone Kubernetes server that runs on your Mac, sothat you can test deploying your Docker workloads on Kubernetes.
The Kubernetes client command,
kubectl , is included and configured to connectto the local Kubernetes server. If you have kubectl already installed andpointing to some other environment, such as minikube or a GKE cluster, be sureto change context so that kubectl is pointing to docker-desktop :
If you installed
kubectl with Homebrew, or by some other method, andexperience conflicts, remove /usr/local/bin/kubectl .
Reset
Reset and Restart options
On Docker Desktop Mac, the Restart Docker Desktop, Reset to factory defaults, and other reset options are available from the Troubleshoot menu.
For information about the reset options, see Logs and Troubleshooting.
Dashboard
The Docker Desktop Dashboard enables you to interact with containers and applications and manage the lifecycle of your applications directly from your machine. The Dashboard UI shows all running, stopped, and started containers with their state. It provides an intuitive interface to perform common actions to inspect and manage containers and existing Docker Compose applications. For more information, see Docker Desktop Dashboard.
Add TLS certificates
You can add trusted Certificate Authorities (CAs) (used to verify registryserver certificates) and client certificates (used to authenticate toregistries) to your Docker daemon.
Add custom CA certificates (server side)
All trusted CAs (root or intermediate) are supported. Docker Desktop creates acertificate bundle of all user-trusted CAs based on the Mac Keychain, andappends it to Moby trusted certificates. So if an enterprise SSL certificate istrusted by the user on the host, it is trusted by Docker Desktop.
To manually add a custom, self-signed certificate, start by adding thecertificate to the macOS keychain, which is picked up by Docker Desktop. Here isan example:
Or, if you prefer to add the certificate to your own local keychain only (ratherthan for all users), run this command instead:
See also, Directory structures forcertificates.
Note: You need to restart Docker Desktop after making any changes to thekeychain or to the
~/.docker/certs.d directory in order for the changes totake effect.
For a complete explanation of how to do this, see the blog post AddingSelf-signed Registry Certs to Docker & Docker Desktop forMac.
Add client certificates
You can put your client certificates in
~/.docker/certs.d/<MyRegistry>:<Port>/client.cert and~/.docker/certs.d/<MyRegistry>:<Port>/client.key .
When the Docker Desktop application starts, it copies the
~/.docker/certs.d folder on your Mac to the /etc/docker/certs.d directory on Moby (the DockerDesktop xhyve virtual machine).
Remote Desktop Mac AppDirectory structures for certificates
If you have this directory structure, you do not need to manually add the CAcertificate to your Mac OS system login:
The following further illustrates and explains a configuration with customcertificates:
You can also have this directory structure, as long as the CA certificate isalso in your keychain.
To learn more about how to install a CA root certificate for the registry andhow to set the client TLS certificate for verification, seeVerify repository client with certificatesin the Docker Engine topics.
Install shell completion
Docker Desktop comes with scripts to enable completion for the
docker and docker-compose commands. The completion scripts may befound inside Docker.app , in the Contents/Resources/etc/ directory and can beinstalled both in Bash and Zsh.
Bash
Bash has built-in support forcompletion To activate completion for Docker commands, these files need to becopied or symlinked to your
bash_completion.d/ directory. For example, if youinstalled bash via Homebrew:
Add the following to your
~/.bash_profile :
OR
Zsh
In Zsh, the completionsystemtakes care of things. To activate completion for Docker commands,these files need to be copied or symlinked to your Zsh
site-functions/ directory. For example, if you installed Zsh via Homebrew:
Fish-Shell
Fish-shell also supports tab completion completionsystem. To activate completion for Docker commands,these files need to be copied or symlinked to your Fish-shell
completions/ directory.
Create the
completions directory:
Now add fish completions from docker.

Yahoo Desktop App
Native Mac apps built with Mac Catalyst can share code with your iPad apps, and you can add more features just for Mac. In macOS Big Sur, you can create even more powerful versions of your apps and take advantage of every pixel on the screen by running them at native Mac resolution. Apps built with Mac Catalyst can now be fully controlled using just the keyboard, access more iOS frameworks, and take advantage of the all-new look of macOS Big Sur. There’s never been a better time to turn your iPad app into a powerful Mac app.
Designed for macOS Big Sur.
How to open all recently closed apps on mac. When an app built with Mac Catalyst runs on macOS Big Sur, it automatically adopts the new design. The new Maps and Messages apps were built with the latest version of Mac Catalyst.
Get a head start on your native Mac app.
Your iPad app can be made into an excellent Mac app. Now’s the perfect time to bring your app to life on Mac. The latest version of Xcode 12 is all you need. Begin by selecting the “Mac” checkbox in the project settings of your existing iPad app to create a native Mac app that you can enhance further. Your Mac and iPad apps share the same project and source code, making it easy to make changes in one place.
Optimize your interface for Mac.
Your newly created Mac app runs natively, utilizing the same frameworks, resources, and runtime environment as apps built just for Mac. Fundamental Mac desktop and windowing features are added, and touch controls are adapted to the keyboard and mouse. By default, your app will scale to match the iPad’s resolution. On macOS Big Sur, you can choose “Optimize interface for Mac” to use the Mac idiom, running your app using the native resolution on Mac. This gives you full control of every pixel on the screen and allows your app to adopt more controls specific to Mac, such as pull-down menus and checkboxes.
Even more powerful.
The new APIs and behaviors in macOS Big Sur let you create even more powerful Mac apps. Apps can now be fully controlled using just the keyboard. You can create out-of-window and detachable popovers, control window tabbing using new window APIs, and make it easier for users to select photos in your app by using the updated Photos picker. iOS Photos editing extensions can now be built to run on Mac. And your app is even easier to manage when it’s running in the background with improved app lifecycle APIs.
New and updated frameworks.
Mac Catalyst adds support for new and updated frameworks to extend what your apps can do on Mac. HomeKit support means home automation apps can run alongside the Home app on Mac. The addition of the ClassKit framework lets Mac apps track assignments and share progress with teachers and students. Plus, there are updates to many existing frameworks, including Accounts, Contacts, Core Audio, GameKit, MediaPlayer, PassKit, and StoreKit.
