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.

Jun 21, 2019 If you can't get an external hard drive or USB flash drive to mount when you plug it in your Mac, you usually open Disk Utilities and try from there. If that doesn't work, try this Command Line. Nov 08, 2019 Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window. MacOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS).

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.

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

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.

Summary

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.

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).

Open/Extract DMG File on Linux

Mount dmg mac command line

You can use command mount to mount DMG file as a virtual drive.

First, you must login as a root user, and then create a directory for DMG image

Open Mac Command Line

# mkdir -p /mnt/macimage

Use mount command as follows to mount DMG file called image.dmg:

# mount -o loop -t hfsplus image.dmg /mnt/macimage

If the DMG is HFS file system, use:

# mount -o loop -t hfs image.dmg /mnt/macimage

Change directory to list files stored inside an DMG image:

# cd /mnt/macimage
# ls -l

Unmount the DMG image, type:

# umount /mnt/macimage

Alternatively, you can use p7zip to extract the DMG file. p7zip is the Unix command-line port of 7-Zip, a file archiver that archives with high compression ratios.
