A .DMG file is a container file commonly used to distribute applications for Mac OS X. Installing software from one of these requires you to mount the image and move its contents to your computer's 'Applications' directory.
One of the most common mistakes I see among new Mac users is fumbling with how to install and open .dmg files or new software. The process for installing new applications on your Mac can be confusing at first because it differs greatly from Windows' software installation process. Nevertheless, the Mac method of installing software is actually quite simple and intuitive once you are accustomed to it. If your desktop is littered with DMG files and white 'drive'-looking icons, read on!
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 administrator password) wait for the copy process to finish. A file with the DMG file extension is an Apple Disk Image file, or sometimes called a Mac OS X Disk Image file, which is basically a digital reconstruction of a physical disc. For this reason, a DMG is often the file format used to store compressed software installers instead of having to use a physical disc. Manually creating DMG Files is extremely simple, but if you still feel that you would like to explore the option of downloading a DMG application, research the different apps out there and compare their ratings and customer reviews. There are a few options out there that have helped to make the process of creating a DMG File much simpler. Try this, select your.dmg file and open with Disk utility 02. Select your Mac os X image from left panel box and then choose restore 03. Drag and drop the Mac os image to source. Install Programs from DMG Files on Mac. Open the DMG File. You can open the DMG file by double clicks or Disk Image Mounter feature (from the sub-menu of Open With) in its right-click menu. Or you can use Attach feature of iSunshare BitLocker Genius to access the DMG file. Tips: iSunshare BitLocker Genius also has the powerful BitLocker.

What are .DMG Files?
DMG stands for Disk Image, and is a format commonly used to distribute files and applications among Apple computers. A DMG file is like a virtual DVD or hard drive. They can be 'mounted' on your Mac in order to work with their contents, or even burned to an actual physical disc.
In order to understand the concept of a DMG disk image, think of a storage volume such as a CD, DVD, hard drive, or external drive. A DMG file is like one of these devices in that it serves as a means to encapsulate documents, images, software, and other files. The difference is that with a DMG, there is no physical storage medium. There is only the DMG file, which can be written to a hard drive, burned to a CD or DVD, or sent over the Internet.
In order to work with the contents of a DMG file, you must mount the the disk image to your system. This may sound daunting, however 'mounting' a DMG file with Mac OS X is no more complicated than double-clicking it' icon. The operating system will load the load image and place a new icon both on your desktop, and in the sidebar of the Finder. The icon will have the same name as the DMG, and you'll be able to browse through its contents like any other folder.
Once you are done working with the contents of the file, you will want to remove or 'unmount' it from your system. Do this by opening the Finder and clicking the eject icon next to the virtual drive's icon. Or, go to the Desktop, click once on the icon, and press CMD+E.

How to Install and Open .dmg Files on a Mac
Software installation with Mac OS X is very different than in the Windows world. On a Windows PC you run an installer, tick off a few checkboxes, and wait for the progress meter to reach completion. There usually is no such 'installation wizard' on a Mac &emdash; you simply drag and drop the program into your computer's 'Applications' directory. The trick is that most Mac applications are distributed as images called DMG files, and many new Mac users end up running applications directly from the image instead of installing them to the 'Applications' directory.
Enough explanation, here's how to install an OS X app from a DMG file:
- Find the downloaded file, which usually ends up in your Desktop or Downloads folder.
- Double-click the .DMG file to mount it. A new Finder window showing its contents should appear.
- If the window also contains a shortcut icon to 'Applications', drag and drop the app onto the shortcut.
- If not, double-click the mounted volume on your desktop and drag the app icon from there to the 'Applications' icon in the Finder sidebar.

Alright, that was the abridged version. Here's the long version. I've just downloaded the DeskLickr application, and the DeskLickr_1.2.dmg is sitting on my desktop. I double-click it and a new icon labeled 'DeskLickr 1.2' appears on my desktop. Here's what my desktop looks like at this point:
Since most of the time a new Finder window also pops up when the image is ready for use, this one is now sitting on my desktop:
Different applications are going to show you slightly different Finder windows. Each application's designers like to add their own artwork. Glitter aside, most applications are trying to tell you the same thing. See the arrow pointing from the DeskLickr icon to the 'Applications' shortcut? It's telling you to drag and drop the icon into that folder. Once you've done so, the app will be installed.
If a program doesn't provide a shortcut to the Applications folder, you'll need to pop open a new Finder window. Press CMD+N to open a new window, then drag the program over to 'Applications' in the left-hand side of the window.
