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”. 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. So you’re running Linux on your computer, maybe Ubuntu, and you have some files with the.dmg extension.
If you want to convert DMG to ISO, it's good to learn a little about disk image file types and what they're meant for. Essentially, a disk image is a snapshot of the content on a DVD, CD, BRD or even a hard drive. It could be just a set of media files, but it can also contain software installation files. In the second case, the disk image will also need to contain boot information in order to boot from the media.
Specifically, DMG is what Apple uses for the macOS environment, while ISO is more widely used in Windows-based and Linux environment. At times, you may need to convert DMG to ISO so you can mount it as a virtual drive on a Windows machine to extract the contents, view them or burn them to create bootable media. The process to convert DMG to ISO is different based on which operating system you're using for the conversion. This article shows you how to convert DMG files to ISO files on Windows, Mac and Linux.
Method 1: How to Convert DMG to ISO on Windows 10 (DMG2IMG)
DMG2IMG is a software utility that converts DMG files into Apple's older IMG format as well as the universally used ISO format. The process is simple, but it requires some command line work. The steps to use DMG2IMG to convert DMG to ISO have been detailed below:
Step 1. Download and install DMG2IMG on your Windows computer. Once the installation is done, open File Explorer and go to the location where you downloaded the application.
Step 2. Right-click on the folder where the software has been downloaded, and select 'Open command window here…' to launch Command Prompt.
Step 3. In Command Prompt, execute the following command (click Enter after typing in the command):
dmg2img 'C:UsersSample UserDesktopsample.dmg' 'C:UsersSample UserDocumentsConvertedRandom.iso'
Step 4. Please note that the double-quotes are required only if you have a space in your file path. In this example, there's a space between Sample and User, so the quotes are needed. If there are no spaces, you can do away with the quotes.
This method only works in 32-bit Windows versions. The conversion is usually done accurately, but you may come across errors that can corrupt the output ISO file. If you're going to be doing a lot of such conversions from DMG to ISO, we recommend getting a proper software utility.
Method 2: How to Convert DMG to ISO on macOS (Disk Utility)
Mac OS X and macOS offer an easier way to convert DMG to ISO, which is only natural because DMG is the native disk image format used by Apple. The Disk Utility that's built into Mac will help you do the conversion from DMG to ISO. Follow the steps below to convert your disk image files:
Step 1. Launch Disk Utility in Mac from Applications > Utilities.
Step 2. Open a Finder window and double-click on the DMG file to mount it. You should be able to see it on the left panel in Disk Utility.
Step 3. Right-click the DMG file in the left panel and select 'Convert'. In the new window that appears, select 'DVD/CD Master' as your output and click on Save. This will save your DMG file in a format with the extension .cdr.
Step 4. Rename the file by replacing .cdr with .iso. The file is now in the ISO format.
The exported ISO file can now be burned to a disk, or mounted within Mac as a virtual drive so you can view or extract the contents. The conversion process is quick, and it's convenient because it does not require any additional software.
Method 3: How to Convert DMG Files to ISO on Linux
In a Linux machine, you can use Terminal to convert DMG to ISO. For this, you will first need the Linux version of DMG2IMG. You can get it using a Terminal command, as shown below:
Step 1. Execute the following command in Terminal:
sudo apt-get update
sudo apt-get install dmg2img
Step 2. You can now proceed with the conversion command: dmg2img example.dmg example.iso
Step 3. You can also define a specific file path for the output (converted) file, but this basic command is what you need to use for the conversion.
As with any file conversion, the process to convert DMG to ISO could present some hurdles, such as corrupted files at output. If you see this happening multiple times, it's possible that the source file itself is corrupted. In such cases, it's better to try and get an authentic download rather than struggle with a corrupt file. In any case, if you're sure the DMG file is verified, these methods to convert DMG to ISO in Windows, macOS and Linux should work for you.

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)
How To Run Dmg Files In Linux Using
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.
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 All…'
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.'
Step 4: At the command prompt, enter the following command and then Enter: dmg2img source.dmg destination.iso
Convert Dmg To Zip
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.
