Jul 20, 2017 If you’re switching to macOS from Windows, you might be confused about installing software. Sure, there’s the Mac App Store, but not everything is in there. If you look for apps outside the store, you’ll find different kinds of installers: DMG files with apps in them, PKG installers, and simple applications inside ZIP archives. Dec 17, 2019  Mac OS X Leopard 10.5 ISO and DMG Installation Process As all of us are not be equipped with the right knowledge for installing ISO and DMG files on our systems, it’s important to mention the installation process. 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), usually a window opens showing the content as well. Drag the application from the.dmg window into /Applications to install (may need an.

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.

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

The first step is to mount (or attach) the disk image. From the command line, use:
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/'

Earlier this week I was very excited to release OS X El Capitan. /download-mac-os-10116-dmg.html.

You should see this message after the unmount:
'/Volumes/Chicken of the VNC/' unmounted successfully.

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.
