Ubuntu is a common variant of Linux, complete with a user-friendly interface and full flexibility in customizing it via the Terminal window. Windows and Linux share the ability to open ISO files, which are similar to DMG files. Though DMG files are commonly associated with Apple’s operating system, Mac, they can be opened in Linux with a few simple steps.
Alternative downloads. There are several other ways to get Ubuntu including torrents, which can potentially mean a quicker download, our network installer for older systems and special configurations and links to our regional mirrors for our older (and newer) releases.

DMG2IMG is an Apple's compressed dmg to standard (hfsplus) image disk file convert tool. It is derived from dmg2iso v0.2c by vu1tur. It will allow you to convert a DMG file into an IMG file that can be mounted as described in ManageDiscImages. On Ubuntu, you’d do: sudo apt-get install dmg2img. Using dmg2img isn’t very difficult. Type “dmg2img” into the command line followed by the name of the DMG file you want to decompress. The Mac OS X version of Firefox is a good example of a compressed DMG file. Hfs-test$ dmg2img 'Firefox 33.1.1.dmg' dmg2img v1.6.5. Firefox 33.1.1.dmg - Firefox 33.1.1.img decompressing: opening partition 0. Note that step 3 is not very well described – you will end up with a file called “ubuntu.img.dmg” that you will need to rename “ubuntu.img” by just renaming the file in the Mac OS finder. Simply copy and paste the relevant commands into Terminal. Step 2 – Install rEFInd to allow dual booting.
Step 1: Install dmg2img
- Open up your terminal console
- sudo apt-get update
- sudo apt-get install dmg2img
Step 2: convert the .dmg to .img
Once dmg2img is installed, you will want to change our working directory to the .dmg you want to use. in my case, the image.dmg is on my desktop. ( /home/dan/desktop )
- cd /home/dan/desktop
Once you are succesfully in your working directory, you are now read to convert the .dmg file.
- dmg2img /home/dan/desktop/image.dmg /home/dan/desktop/image.img
NOTE: the second part of the command is a .img at the end.
Step 3: Mount the .img file
Now we are ready to mount the .img file into a new directory
Linux Dmg To Usb
- mkdir /media/image
- sudo modprobe hfsplus
- sudo mount -t hfsplus -o loop image.img /media/image
Step 4: Convert the .img to .iso
The image is now mounted. We need to convert it to a .iso file now. Open Brasero, a program native to Ubuntu. It can be found in the “Sound & Video” section under “Applications.” When the window opens, choose “Data Disk” and then “Enable Side Panel.” (if Brasero is not installed, open up the terminal and type the following command: sudo apt-get install brasero )
Press “Image File” and “Burn.” This takes the IMG file and converts it into an ISO file. Wait for this to finish.
Step 5: Mount the .iso file
Enter the following commands into Terminal, where “image” is the name of the ISO:
- mkdir /media/imageiso
- sudo modprobe hfsplus
- sudo mount -t hfsplus -o loop image.iso /media/imageiso
This will successfully mount the .iso file and you can proceed with your installation.
So you’re running Linux on your computer, maybe Ubuntu, and you have some files with the .dmg extension. In this guide, we’re going to talk about how to open, mount, extract, and otherwise get your files from these pesky DMG images. You could always just extract the files on a Mac, then transfer them back to your Linux machine. But if you really want to do this on Linux, without having to rely on Mac, here’s how to do it.
What are DMG image files?
Simply put, it’s a kind of image file. But not an image like a jpeg is an image. DMG is Apple’s proprietary disk image format, native to Mac OS X. There are actually a whole bunch of different types, format and options within this format. There are options for encryption, compression, and different kinds of partition schemes, among others. Unfortunately, this can make things pretty confusing when we’re trying to gain access to the data contained in one of these images.

DMG images are typically a kind of Universal Disk Image Format (UDIF), although there are others, namely NDIF and SPARSE. Although the .dmg file extension is usually used, they can also sometimes have an .img extension, or in some cases no extension at all. Their MIME type is application/x-apple-diskimage.
The HFS/HFS+ (Mac OS Extended/Journaled) file system is typically used in DMGs. However, this isn’t always the case. You may also sometimes find FAT and ExFAT files systems, as well as variations on HFS.
Does my system support DMG?
Perhaps the biggest hurdle to overcome when trying to work with DMG files is working with the HFS file system (Mac OS Extended). Linux supports HFS through the “hfs” and “hfsplus” kernel modules.
There’s an easy way to test if your system has these kernel modules. Plug in a USB drive formatted with the Mac OS Extended file system. If your particular distribution doesn’t have the appropriate modules, you will likely get an error message. On Ubuntu, you’ll get a popup window declaring “Ubuntu: Unable to mount
Alternatively, we can see if the kernel module files are present with find:
We want to see two files: “hfs.ko” and “hfsplus.ko”. If find doesn’t return these files, your system probably doesn’t support HFS.
You could also try “modinfo”: modinfo hfs and modinfo hfsplus should return something like:
If you get 'modinfo: ERROR: Module hfsplus not found' your system doesn’t have these modules.
How To Install Dmg On Mac
Not all Linux kernels and distributions support HFS. This is especially the case for certain distributions that are a few years old. If you have kernel support for HFS, great! If not, don’t worry. There are still ways to extract data from your DMG files. While it’s nice to have the option to mount the images we’re working with, this is really the only functionality we’re losing without having the hfs and hfsplus modules. The two programs we’re going to use later on (P7ZIP and dmg2img) do not require kernel support to function.
What kinds of DMG images can be opened in Linux?
This guide is about how to open, mount, and extract files from read/write, read only, and compressed DMG image files. The following partition schemes have all been tested with the techniques discussed here.
- Apple Partition Map
- CD/DVD (partitioned)
- CD/DVD (partitioned) with ISO data
- Hard disk
- Master Boot Record Partition Map
- No partition map
This guide does not cover how to handle sparse disk images (.sparseimage), sparse bundle disk images (.sparsebundle), or CD/DVD masters. DMG images with partition scheme types of “CD/DVD” and “GUID Partition Map” do not appear to work with the techniques described here.
Option 1: Mount the DMG
If the Linux distribution you’re on has HFS support in the kernel (Ubuntu 14.04.1 LTS supports it), it’s pretty easy to just mount the DMG image:
We’re using “sudo” because we need root privileges to mount things. The HFS+ file system type is specified with “-t hfsplus”. The “/mnt” at the end of the command specifies where we’re mounting the image.
Unmount the image with sudo umount /mnt
If you get a wrong fs type message like the one below, it means the DMG file is either of an unsupported type, or it’s compressed. Unsupported images include sparse images, sparse disk bundles, CD/DVD masters, and images with partition schemes of the CD/DVD or GUID Partition Map types.
Use “file” to learn a little more about the image file:
If you get image.dmg: x86boot sector that means it’s probably using a GUID Partition Map and isn’t supported. This isn’t good, however, it’s also not too terribly common.
What’s more common is to see something like this:
If mounting isn’t working, and this is what you’re seeing with “file image.dmg”, then you’re luck!. Our problems are being caused by compression. Linux doesn’t like to mount compressed DMG images. To get around this little obstacle, we’ll use dmg2img (see below).
Option 2: Use dmg2img for compressed images
So you have a DMG image that you can’t mount because it’s compressed. You’ve done “file compressed_image.dmg” and you got “compressed_image.dmg: bzip2 compressed data”. The fix? That’s easy: use dmg2img to convert it to an uncompressed image. Once you run the image through dmg2img you should be able to mount it no problem.
Don’t have dmg2img? It’s usually pretty easy to get using your distribution’s package management. On Ubuntu, you’d do:
Twitter dmg. The latest Tweets from dmg04 🛬 San Diego (@Admg04). What's Up, DOC? Community Manager at Bungie. For Help Articles and Guided Support, please visit.
Using dmg2img isn’t very difficult. Type “dmg2img” into the command line followed by the name of the DMG file you want to decompress. The Mac OS X version of Firefox is a good example of a compressed DMG file.
Now mount the resulting .img file:

Option 3: Extract DMG contents with P7ZIP
P7ZIP is awesome. It’s the Linux/BSD version of 7-Zip. Check out their SourceForge page here With it you can literally extract files from any kind of image or archive. Just kidding… It doesn’t really work with every format conceivable. However, it can handle (in alphabetical order): ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR and Z. Impressed? I certainly am!
Installing p7zip is pretty easy using your distribution’s package management system. On Ubuntu with apt-get:
In addition to being able to extract data from compressed and uncompressed images alike, P7ZIP doesn’t require the HFS kernel modules at all. In the example below, we’re going to extract all of the files from “Firefox 33.1.1.dmg”. When we’re done, we’ll have a tidy little folder called “Firefox”.
Jul 31, 2014 No one knows when Office for Mac 2013 or 2014 will be available. Typically the mac version comes 1 year or so after the windows version and it is numbered as such (Windows Office 2010, Mac Office 2011). Mar 04, 2015 To install this update. Office 365 Commercial customers can get the new Outlook for Mac by accessing their Office 365 Portal, (Gear icon Office 365 Settings Software Outlook for Mac icon) or visiting the Software page; Office 365 consumer subscribers can get the new Outlook for Mac by going to their My Account page.; For people who already have Office for Mac 2011 and Outlook for Mac.

Invoke P7ZIP to extract archives and images with “7z x”.

Notice that 7z extracted three files: “0.ddm”, “1.Apple_partition_map”, and “2.hfs”. To actually get to the files, we’ll need to run 7z again on “2.hfs”.
We picked “2.hfs” because it was the biggest of the three, meaning it was probably the one with the data. Simple but effective logic. After a few moments, you should have a folder called “Firefox” with all of the files from the original DMG.
