MacOS Catalina DMG is the original file of Mac Operating system which is available on App Store for free for Mac users. If you have an iMac or MacBook device so you can officially download it via the app store. If you donât have it click the link above to download it. Please be advised that read. Convert DMG to ISO (MacOS X, Windows or Linux) With Disk Images we mean a full âcopyâ image of for example a CD, DVD or Harddisk. DMG âs are typically used to distribute applications. Some times however youâd prefer a ISO or a CDR image instead, for example for users on different platforms, or for offering other ways to burn an image to CD or DVD (if applicable). DMG files use Hierarchical File System (HFS) as a disk file system format. In order for your Linux machine to open DMG files it needs to support HFS and HFS+. To enable HFS and HFS+ support on your Linux machine you will need to install HFS tools and kernel modules. HOWTO Convert an ISO file to a DMG file with no additional software. This article gives you two ways to convert an ISO file to a DMG file using nothing but your Mac & OS X. DMG files are very common on the MacOS X platform, used for Disk Images. With Disk Images we mean a full âcopyâ image of for example a CD, DVD or Harddisk. DMGâs are typically used to distribute applications. Some times however youâd prefer a ISO or a CDR image instead, for example for.
So youâre running Linux on your computer, maybe Ubuntu, and you have some files with the .dmg extension. In this guide, weâre 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, hereâs how to do it.
What are DMG image files?
Simply put, itâs a kind of image file. But not an image like a jpeg is an image. DMG is Appleâs 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 weâre 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 isnât 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 âhfsâ and âhfsplusâ kernel modules. Mac uninstall cleaner.
Thereâs 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 doesnât have the appropriate modules, you will likely get an error message. On Ubuntu, youâll get a popup window declaring âUbuntu: Unable to mount '.
Alternatively, we can see if the kernel module files are present with find:

We want to see two files: âhfs.koâ and âhfsplus.koâ. If find doesnât return these files, your system probably doesnât support HFS.
You could also try âmodinfoâ:
modinfo hfs and modinfo hfsplus should return something like:
If you get '
modinfo: ERROR: Module hfsplus not found ' your system doesnât have these modules.
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, donât worry. There are still ways to extract data from your DMG files. While itâs nice to have the option to mount the images weâre working with, this is really the only functionality weâre losing without having the hfs and hfsplus modules. The two programs weâre 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.
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 âCD/DVDâ and âGUID Partition Mapâ do not appear to work with the techniques described here.
Option 1: Mount the DMG
If the Linux distribution youâre on has HFS support in the kernel (Ubuntu 14.04.1 LTS supports it), itâs pretty easy to just mount the DMG image:
Weâre using âsudoâ because we need root privileges to mount things. The HFS+ file system type is specified with â-t hfsplusâ. The â/mntâ at the end of the command specifies where weâre 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 itâs 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 âfileâ to learn a little more about the image file:
If you get
image.dmg: x86boot sector that means itâs probably using a GUID Partition Map and isnât supported. This isnât good, however, itâs also not too terribly common.
Whatâs more common is to see something like this:
If mounting isnât working, and this is what youâre seeing with âfile image.dmgâ, then youâre luck!. Our problems are being caused by compression. Linux doesnât like to mount compressed DMG images. To get around this little obstacle, weâll use dmg2img (see below).
Option 2: Use dmg2img for compressed images
So you have a DMG image that you canât mount because itâs compressed. Youâve done âfile compressed_image.dmgâ and you got âcompressed_image.dmg: bzip2 compressed dataâ. The fix? Thatâs 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.
Donât have dmg2img? Itâs usually pretty easy to get using your distributionâs package management. On Ubuntu, youâd do:
Using dmg2img isnât very difficult. Type âdmg2imgâ 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. Itâs 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 doesnât 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 distributionâs package management system. On Ubuntu with apt-get:
In addition to being able to extract data from compressed and uncompressed images alike, P7ZIP doesnât require the HFS kernel modules at all. In the example below, weâre going to extract all of the files from âFirefox 33.1.1.dmgâ. When weâre done, weâll have a tidy little folder called âFirefoxâ.
Invoke P7ZIP to extract archives and images with â7z xâ.
Notice that 7z extracted three files: â0.ddmâ, â1.Apple_partition_mapâ, and â2.hfsâ. To actually get to the files, weâll need to run 7z again on â2.hfsâ.
We picked â2.hfsâ 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 âFirefoxâ with all of the files from the original DMG.
DMG is Apple's file format for disk image, similar to ISO for Windows. It offers an easy information sharing and software distribution for Mac users. But it's not an user-friendly format for Windows since .dmg file can not be natively handled, such as burning DMG to USB. For that reason, no matter what platform you're using, you will need to first convert the DMG into ISO so that it can be used on a Windows machine. We've shown you how to do this on three different platforms: Linux, Mac and Windows.
One thing to remember about this process is that DMG files won't always work for software installations after converting them to ISO. The reason is that applications have to be designed differently for Windows and Mac, and they're not interchangeable. However, you can use this method to extract the contents of the file once it has been converted to ISO. For media and other content types, this is an ideal way to do it.
Part 1: How to Convert .dmg to .iso on Linux (Ubuntu)
The best thing about Linux is that you can complete a lot of tasks totally for free. All apps are distributed in open source license, meaning you don't need to pay a single peny to use the app. Actually, there is a package called dmg2img, which is able to convert .dmg file to ISO with a set of text commands. Taking Ubuntu as an example at here.
Ipvanish download mac. Step 1 : Lanuch Terminal app and update the system via this command (sudo apt-get update)
Step 2: After the package installed sucessfully, then input this command to install the package (sudo apt-get install dmg2img)
Step 3: Finally input this command to convert DMG to ISO (dmg2img demo.dmg demo.iso)

Replace the example files with the real file names. You must also run Terminal in the same directory location as your DMG file.
Part 2: How to Convert DMG to ISO on Mac
In a Mac computer, you can use a different command line input in Terminal, or you can use the native Disk Utility to convert DMG into ISO. Both methods have been shown below:
Terminal: The command line input is different from what you would use for Windows. It uses the hdutil program to convert the DMG file into its ISO equivalent. Open a Terminal instance by clicking Applications >Utilities >Terminal.
In the Terminal window, execute this command: hdiutil convert /path/to/example.dmg -format UDTO -o /path/to/example.iso
Be sure to put in the right source and destination files with their complete file paths in the above command. Your ISO file will be ready once you hit Enter.
Disk Utility: Open Disk Utility from Applications >Utilities. Mount the DMG file by double-clicking on it. You will now be able to see it within Disk Utility. The DMG mount must be right-clicked, after which you can choose 'Convert' in the context menu.
In the next dialog box, click on 'DVD/CD Master' when asked to specify the image format. Now hit 'Save'. Locate the saved file, which will be a .cdr file. You can now rename the file and change the file extension from .cdr to .iso.
Part 3: How to Convert DMG to ISO on Windows
To convert a DMG file to ISO in Windows, you will need a special utility. The one we've shown here is called dmg2img, and it can be run from the command line to convert one format to the other. IMG is Apple's old disk image format, which transitioned into DMG with Mac OS X. However, we don't need the IMG format, since we're going to convert the DMG directly into ISO with this method. Follow the steps described below:
Step 1: Download the win32 binary for the application from this page.
Step 2: Go to the Downloads folder in File Explorer and right-click on the zipped file. In the context menu, click on 'Extract Allâ¦'
Step 3: Extract it to the same folder (Downloads), then right-click the Downloads folder while holding down the Shift key. This will show another context menu, where you can click on 'Open command window here.'
Linux Mint Convert Dmg To Iso
Step 4: At the command prompt, enter the following command and then Enter: dmg2img source.dmg destination.iso
Step 5: The above command should be modified to include the file path with file name for both the source and destination files. You can choose to create the ISO in the same Downloads folder, or another location of your choosing.

These different ways are designed to help you convert DMG into ISO, which can then be used on a Windows machine, including ISO burning, editing, creation, etc. There are several other workarounds for this, but be cautious when using unknown software. If the DMG file is corrupted during the conversion process, the resulting ISO file will be unusable. To make sure there are no problems, only use the command line input or a trusted application for this purpose. If you'd rather not risk using command prompt or free software, there are several premium tools that can help you convert DMG to ISO on Windows, Mac and Linux computers.
