An intrepid reader asked the following question:
How do you install a .dmg package from the command line?
Many applications are distributed as disk images, a compressed binary format. If you double click a disk image in the Finder, it is mounted automatically. Once mounted, installation of the application is typically done by dragging an icon to the Applications folder. The same can be accomplished from the command line using two commands,
hdiutil
and cp
.- To install from a.dmg file you usually do the following: double click the.dmg to make its content available (name will show up in the Finder sidebar). Drag the application from the.dmg window into /Applications to install. Wait for the copy process to finish. Eject the.dmg (by clicking.
- The Mac has finally released dark mode thanks to macOS Mojave. Just brought toggle to preferences, The dark mode entire macOS operating system. From it is own Apps like and Photos, iTunes and complete window filters. And you are allowed to install and use Xcode easily on it. In macOS Mojave, the new feature is called Stack.
The following steps show the installation of a popular VNC client for OS X called 'Chicken of the VNC'. It can be used as a remote desktop client for Linux, Mac, or Windows hosts.
The download file is named 'cotvnc-20b4.dmg'. Here are the steps needed to install it remotely from the command line.
note: this technique can be used from a local Terminal window or a remote SSH connection.

Mount the disk image
Jun 29, 2019 As you know MacOS Catalina has many new features that are useful for you, in this case, you will need to download macOS Catalina vmdk file, However, the MacOS Catalina 10.15 dmg File is available now. Therefore, download MacOS Catalina dmg file and install MacOS Catalina on virtualization software or on your computer. Method 3: Mount.dmg file using iSumsoft Bitlocker Reader for Mac Step 1: Download and install iSumsoft Bitlocker Reader for Mac on your Mac computer. After the installation is complete, launch it from the Launchpad. Step 2: Click the Attach button. Step 3: Browse for the.dmg file and select it.
The first step is to mount (or attach) the disk image. From the command line, use:
I received the following output:
hdiutil mount cotvnc-20b4.dmg
I received the following output:
A mounted disk image appears on the Desktop, in the Finder, and more importantly shows up as a directory in /Volumes. In this case, the last line of output from hdiutil showed exactly where the disk image was mounted.
Sometimes when a disk image is mounted, it will prompt you to agree to a license first. In that case, the text that would normally appear in a GUI dialog box instead appears in the Terminal window. Once you scroll to the bottom of the agreement, you can type in Y to continue or N to stop. The Firefox disk image is one example of a package that displays a license before mounting.
Install the application
Use the
cp
command to copy the application to /Applications:sudo cp -R '/Volumes/Chicken of the VNC/Chicken of the VNC.app' /Applications
The
-R
switch means to copy recursively, in other words, copy everything from that location including all subdirectories and files below. It is important to leave off the trailing '/' from the 'Chicken of the VNC.app' directory, or the command will not copy the directory itself, just the contents. After entering your password, the application will be installed and ready to use. Most applications can simply be copied to the /Applications directory. However, some are distributed in a .pkg format and must be installed using the
installer
command instead of cp
. To install a .pkg, use this command:sudo installer -package /path/to/package -target '/Volumes/Macintosh HD'
Unmount the disk image
To tidy up, return to your home directory and unmount the disk image:
cd ~
hdiutil unmount '/Volumes/Chicken of the VNC/'
You should see this message after the unmount:
'/Volumes/Chicken of the VNC/' unmounted successfully.
Install Dmg File On Windows
Installing applications from a .dmg package at the command line is not something you need to do every day. But it is a nice tool to have if you want to install an application on a remote server or script the installation of a package to a group of desktop Macs.

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
- Double-click

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.
Mac Install Dmg Package
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.
