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

The standard pkg and the seemlingly standard (but not) dmg. The pkg option will build a standard pkg installer file, which will install with any system that can install pkg files. The dmg option will build a standard dmg disk image file, with the payload of the installer as contents. Jan 28, 2016 So many of you are wondering how you can mount a DMG (disk image) clone which will allow you to use migration assistant to pull data from it. Here I'll show you the easiest and best way to do this. Background: As of Mavericks (10.9 and the current OSs) Apple did something stupid, they removed DMG support for migration assistant.

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:

How To Mount 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:

That's it for today, hope you liked the post! Let me know!

DMG is a file of Apple Disk Image. The Apple Disk Images are disk image files commonly used by the Mac OS X operating system. When opened, an Apple disk image is 'mounted' as a volume within the Finder. Several Apple proprietary disk image formats can be used to create these images, including the Universal Disk Image Format (UDIF) and the New Disk Image Format (NDIF). Apple disk images usually have the .dmg file extension.

Apple disk images allow secure password protection as well as file compression and hence serves both security and file distribution functions; they are most commonly used to distribute software over the Internet.

Universal Disk Image Format (UDIF) is the native disk image format for Mac OS X. Disk images in this format typically have a .dmg extension. New Disk Image Format (NDIF) was the previous default disk image format in Mac OS 9, and disk images with this format generally have a .img (not to be confused with raw .img disk image files) or .smi file extension. Files with the .smi extension are actually applications that mount an embedded disk image, thus a 'Self Mounting Image', and are intended only for Mac OS 9 and earlier. A previous version of the format, intended only for floppy disk images, is usually referred to as 'Disk Copy 4.2' format, after the version of the Disk Copy utility that was used to handle these images. A similar format that supported compression of floppy disk images is called DART. Apple disk image files are published with a MIME type of application/x-apple-diskimage.

Different file systems can be contained inside these disk images, and there is also support for creating hybrid optical media images that contain multiple file systems. Some of the file systems supported include Hierarchical File System (HFS), HFS Plus, File Allocation Table (FAT), ISO9660 and Universal Disk Format (UDF).
