Open DMG File
If your files are already inside the folder that you’ve organized, then you can just go to the next step. Using macOS Disk Utility to create DMG file. Next step, go to Finder Application Utilities and open macOS Disk Utility App. In the macOS Disk Utility App, go to File New Image Image from Folder. See screenshot below. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below: sudo apt-get install dmg2img Once installed, run the following command: dmg2img filename.dmg That will convert the.dmg to,img file in ISO format. Then just run. Mv filename.img filename.iso.
DMG is used for disk image files on Macintosh computers running Mac OS X. This file extension replaces the older file extension IMG which was discontinued during the release of later series of Mac operating systems. You can open DMG file on Mac, Linux, and Windows operating systems but it will require additional software to be installed on Windows. Note that on Windows and Linux you cannot open every DMG file, since there are certain software limitations on DMG format variation.
DMG files are used by Apple for software distribution over the internet. These files provide features such as compression and password protection which are not common to other forms of software distribution file formats. DMG files are native to Mac OS X and are structured according to Universal Disk Image Format (UDIF) and the New Disk Image Format (NDIF). They can be accessed through the Mac OS Finder application by either launching the DMG file or mounting it as a drive.
DMG is also referred to as the Apple’s equivalent to MSI files in Windows PC. Non-Macintosh systems may access DMG files and extract or convert them to ISO image files for burning. Several applications are designed to offer this solution for Windows systems.
7-Zip and DMG Extractor are the best options to open DMG file on Windows because they are compatible with the most DMG variations. For Linux a built-in 'cdrecord' command can be issued to burn DMG files to CD's or DVD's.
Aside from the Finder application, you can open DMG files through Apple Disk Utility, Roxio Toast, and Dare to be Creative iArchiver for Mac platform. On the other hand, additional applications such Acute Systems TransMac, DMG2IMG, and DMG2ISO can be installed on Windows to fully support the files.

DMG files are transferred over e-mail or internet using application/x-apple-diskimage multipurpose internet mail extensions (MIME) type.
Following file types are similar to DMG and contain disk images:

DMG files are proprietary disk image files used for software distribution in Mac OS. Providiing both password protection and bzip2-like compression, these files are perfect packaging medium.
Usually DMG files are opened automatically when you click them in Finder. They appear as a folder with files, but actually Finder mounts each DMG file as a separate filesystem and then shows you its contents. If you're observant enough, you'll see that in the left side panell of Finder you have all the active DMG filesystems listed and ready to be ejected once you finish copying the files or installing new software.
Sometimes you may want to download and mount DMG file using Mac OS command line, and in this post I'll show you how to do it

Why would you want to mount DMG files manually?
I've been business traveling quite a bit lately which means I'm most of the time away from my home computer. Naturally, I have configured Remote Desktop access so that I can use my iPad to access my desktop whenever I need, but sometimes it takes forever to do some simple things just because of the graphics environment overhead.
If you're like me, you'll probably find Remote Desktop over 3G to be pretty boring, and will want to do as much as you can via command line.
Mounting DMG with hdiutil command
In order to manually mount DMG file, you'll need to use hdiutil command. You don't have to be a privileged user, so can do it as your own user.

For this example, I'm going to use the command line interface (CLI) for the excellent HandBrake tool, which is great for converting all sorts of videos into iPad and iPhone friendly resolution and mp4 format
Let's mount the image from my dmg file:
As you can see from this output, the mount was successful and you now have the filesystem from DMG package available under the /Volumes/HandBrake-0.9.8-MacOSX.6_CLI_x86__64 directory.
Don't want to to take my word for it? Let's use the standard mount command to confirm that indeed we now have an new filesystem mounted:
Ejecting mounted DMG images from command line
Once you are done with whatever you were trying to do, there's no longer a reason to keep your DMG image mounted, so you should unmount it. While it's possible to use umount command, I think it makes more sense if you use the same hdiutil tool that helped you mouunt the DMG image in the first place.
Here's how you can eject the DMG image using hdiutil:
