Change Download Location for Messages App On Mac. Follow the steps below to Change Download Location for Messages App on Mac. Open the Messages App on your Mac. Next, click on the Messages tab in the top Menu bar of your Mac and then click on Preferences option in the drop-down menu.
Computers are fully embedded into our lives, both at work and at home. Checking email, organizing calendars, reading documents, shopping online, and surfing the web — all form the backdrop of our everyday. These activities are so commonplace and accessible that it’s easy to overlook the finer points of how your computer performs each task and what apps it uses to help you get the job done.
- Apps that are marked with a blue check mark have permission to the service highlighted in the left pane of the window. If you don't see any apps here, it's because you have none that perform the selected service's function. If the apps and check boxes are greyed out, click on the padlock icon in the bottom, left corner of the window.
- Changing the Default App. If you want to change the default app that opens a certain file type, you need to find a file that has the correct file type. So if you want all PNG files to open in a new app, you will need an PNG image to perform this. Locate your file and right click (Alt click) on the icon. This will bring you a menu with a.
Apps are computer programs designed to interact with files and create a seamless transition for everything from booting up your Mac to working online. All computers come with a host of apps already installed. For example, computers running macOS come with Safari, made by Apple. This browser is already installed and ready to access the internet.
In other words, Safari is set to “default” browser, which means whenever you click a link to a website, it’ll always open it up using Safari. However, there are lots of other compatible browsers for Mac, and you might find yourself wondering how to change default browser on macOS or looking to fine-tune other default settings.
Why Should I Change Default Applications?
Most of the time, default apps have the basics covered, however you may be itching for a change because they may not be providing the features you need. If you find another app better suited to your needs, it’s best to make the change permanent.
By changing default apps to the ones you prefer, you’ll have more control over how you work with your files and be able to skip the headache of re-opening files with a new app every time, saving you precious minutes. Thankfully, changing default settings is fairly easy.
Changing default apps for specific file types
One upgrade you might consider right away is to change the default PDF viewer on Mac to something like PDFpen, or another advanced PDF reader. PDFs are one of the most common files types encountered daily. Used in contracts, university reading packages, or fillable forms, PDFs are popular for a good reason: any computer can open and read a PDF, and the format holds its layout. No matter what programs were used to create it, a PDF will generally look the same on everyone’s computer.
PDFpen is a great addition to your Mac. It has all the basic tools for editing and note-taking, but is also packed with advanced options for the increasingly paperless world: redaction features, signatures, notations, filling out or editing sections, and even highlighting and searching for certain terms within the document.
Here’s how to change default PDF viewer on Mac to PDFpen:
- In your Finder locate a .pdf file and right-click on it
- Select Get Info from the dropdown menu
- Expand the Open With section and select PDFpen
- Once selected, click the Change All button below the dropdown menu. A pop-up will appear asking if you’re sure, click Yes.
Now the change should be implemented for all .pdf files. Test it by returning to the Finder and opening any .pdf. If it launches in PDFpen. you know it has worked. Further, you can use the same steps to set other defaults apps for different kinds of files: instructing all .jpeg files to open with CameraBag Pro, for example.
If you ever need to know how to make Preview default app again, just repeat the steps above but select Preview instead of PDFPen when you reach the Open With selection.
Changing your default browser
You already know what is the default browser for Mac OSX: Safari. And while Safari is a generally excellent option, there are other great browsers for Mac — one of the most popular being Google Chrome. Along with its reputation for being faster than other browsers, Chrome seamlessly syncs with services you may have been using all the time, such as Gmail, Chromecast, or GCal.
Knowing how to change default browser on Mac will never be a challenge. It’s arguably the easiest change to make because all browsers compete to report usage, so whenever they detect they are not being used every time they produce a pop-up asking to be default. This may seem like it makes directions for how to change default browsers obsolete, usually downloading the browser you want and opening it for the first time will set you on the path to default status. But occasionally a careless mis-click will find you on the wrong end of an unwanted Yahoo search bar.
To make Chrome default browser on Mac, begin by downloading Chrome if you haven’t already. Then follow the directions below according to which operating System your Mac is currently running.
How to make Chrome default browser on macOS Mavericks or earlier:
- Launch Safari by clicking the compass icon
- Click on the Safari menu in the top-left corner and select Preferences
- Navigate to General
- Choose Chrome as the default by selecting it from the menu
- Close Preferences
- Quit Safari
If you don’t see a default option in Preferences, don’t panic. You may need to use different instructions if your Mac is running on El Capitan or Yosemite.
How to make Chrome default browser on El Capitan or Yosemite:
- Launch System Preferences from the Dock or Finder
- Select General from the top left of the window
- Find the dropdown next to “Default web browser”
- Choose the web browser you'd like to use as the default and close System Preferences
Your preferences will be automatically saved. You can test it by performing a search in Spotlight and clicking a web result. If the site opens in Chrome, you’ll know you have successfully set Chrome as default browser.

Change your default email app
We spend so much time checking, writing, and organizing emails that having an email client designed to save you time is key. With this in mind, you may want to further customize your Mac by selecting a better email client. Much like a PDF reader opens .pdf files and a browser allows you to surf the web, your email client sets up a place for you to easily check and respond to your emails.
While many check their emails in browsers for convenience if they move between computers, a better, more secure option is Canary Mail.
Canary Mail focuses on security and this is what makes it outstanding. In addition, its concept and design are no-nonsense. Canary works with all the email providers you already have and has tools for dealing with volumes of unwanted emails or unused threads in bulk. It also uses algorithms to learn what you need and optimizes your productivity.
Right now, Mail is likely the default email app on your Mac. The steps below outline how to change default program on Mac to a third-party one. If you have some email client already downloaded, you can still use the steps below to change the default email client from Mail. Just sub the name of your app in place of Canary. Just in case, Canary Mail download is available here.
Switch the default email client from Mail to Canary:
- Launch Mail by clicking the icon in the Dock or searching for it with Finder
- At the top of the screen, click Mail in the menu bar and then Preferences
- Select the dropdown next to Default Mail Reader
- Choose Canary as the default
This change should take immediate effect.
Switching and customizing your default apps will improve your interactions with your Mac, enhancing how you experience the activities you spend time doing everyday by making them faster and easier.
Once you know how to switch the default apps, you may find yourself customizing other aspects of your computer use. PDFpen and Canary Mail are both offered as free trials from Setapp — a platform for over 150 unique and useful Mac apps — so there is no risk to trying something new. If you don't like it, you can always go back and change the default again at any time.
So whether you are running a faster browser, highlighting and making notes in the margin for school, or simply clearing out junk-mail now that you can change default application on macOS you can take control of the finer points of how your Mac runs. Small daily tasks will wrap up faster and look better.

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:
-
Start Docker Desktop when you log in: Automatically starts Docker Desktop when you open your session.
-
Automatically check for updates: By default, Docker Desktop automatically checks for updates and notifies you when an update is available. You can manually check for updates anytime by choosing Check for Updates from the main Docker menu.
-
Include VM in Time Machine backups: Select this option to back up the Docker Desktop virtual machine. This option is disabled by default.
-
Securely store Docker logins in macOS keychain: Docker Desktop stores your Docker login credentials in macOS keychain by default.
-
Send usage statistics: Docker Desktop sends diagnostics, crash reports, and usage data. This information helps Docker improve and troubleshoot the application. Clear the check box to opt out.Click Switch to the Edge version to learn more about Docker Desktop Edge releases.
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:
-
Add a Directory: Click
+
and navigate to the directory you want to add. -
Apply & Restart makes the directory available to containers using Docker’sbind mount (
-v
) feature.
Tips on shared folders, permissions, and volume mounts
-
Shared folders are designed to allow application code to be edited on the host while being executed in containers. For non-code items such as cache directories or databases, the performance will be much better if they are stored in the Linux VM, using a data volume (named volume) or data container.
-
By default, Mac file systems are case-insensitive while Linux is case-sensitive. On Linux, it is possible to create 2 separate files:
test
andTest
, while on Mac these filenames would actually refer to the same underlying file. This can lead to problems where an app works correctly on a Mac (where the file contents are shared) but fails when run in Linux in production (where the file contents are distinct). To avoid this, Docker Desktop insists that all shared files are accessed as their original case. Therefore, if a file is created calledtest
, it must be opened astest
. Attempts to openTest
will fail with the errorNo such file or directory
. Similarly, once a file calledtest
is created, attempts to create a second file calledTest
will fail. For more information, see Volume mounting requires file sharing for any project directories outside of/Users
.)
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.
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.
Command 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
:
How To Change Mac Name
If you installed
kubectl
with Homebrew, or by some other method, andexperience conflicts, remove /usr/local/bin/kubectl
.
-
To enable Kubernetes support and install a standalone instance of Kubernetesrunning as a Docker container, select Enable Kubernetes. To set Kubernetes as thedefault orchestrator, select Deploy Docker Stacks to Kubernetes by default.Click Apply & Restart to save the settings. This instantiates images required to run the Kubernetes server as containers, and installs the
/usr/local/bin/kubectl
command on your Mac.When Kubernetes is enabled and running, an additional status bar item displaysat the bottom right of the Docker Desktop Settings dialog.The status of Kubernetes shows in the Docker menu and the context points todocker-desktop
. -
By default, Kubernetes containers are hidden from commands like
dockerservice ls
, because managing them manually is not supported. To make themvisible, select Show system containers (advanced) and click Apply andRestart. Most users do not need this option. -
To disable Kubernetes support at any time, clear the Enable Kubernetes check box. TheKubernetes containers are stopped and removed, and the
/usr/local/bin/kubectl
command is removed.For more about using the Kubernetes integration with Docker Desktop, seeDeploy on Kubernetes.
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).
-
You need to restart Docker Desktop after making any changes to the keychainor to the
~/.docker/certs.d
directory in order for the changes to takeeffect. -
The registry cannot be listed as an insecure registry (see DockerEngine. Docker Desktop ignores certificates listedunder insecure registries, and does not send client certificates. Commandslike
docker run
that attempt to pull from the registry produce errormessages on the command line, as well as on the registry.
Directory 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.
