Dmg File On Windows

What is DMG file

A DMG File stands for Disk Image file and it is a file format which is used to create mountable disks on the Macintosh operating system. The DMG File format contains data in the form of blocks which are often secured using encryption methods or are compressed using compression algorithms. DMG files are used for installing tools and softwares into the Mac OS operating system. The file is downloaded from the internet from the software manufacturer’s website and upon mounting the DMG file, a virtual disk is generated from where the user can either copy the application to the applications folder or run an installation script depending on the type of installation.

To create a bootable USB drive from a DMG file on Windows, you will need to have the right utility. That's because DMG is not native on Windows. It is the Mac equivalent of an ISO file that has been in use since Apple transitioned from the IMG format with Mac OS X. A DMG file, like ISO, can be used to install macOS operating system or Mac apps. DMG file is a compressed file format being used widely on Mac computer. Windows OS doesn't natively support DMG disk image files, so if you need to create a bootable USB drive from a DMG file, mostly for bootable Mac OS X or macOS installation USB, you need a special utility to help you complete the task. DMG files include something called a checksum, which basically verifies that the file is 100% intact. This is what you see when the file is opening: This little window first goes through a phase of verifying the file, and then once it’s sure the file is good, moves on to decompressing it. DMG files are not natively supported by Microsoft Windows OS. DMG format is a native Mac OS disk image format which is used to distribute installation packages within Mac OS. In order to open DMG file on Windows you will need a special software which has support for this format. DMG files are macOS disk image files. They are much like ISO files—their Windows-based counterpart. These disk images normally contain program installation files for macOS apps, but they can also be used to hold compressed files. If it’s an app written for macOS, you obviously won’t be able to install and run the app on Windows.

The newer disk image file was used in place of the original IMG or image file which was used in earlier versions of mac that are classic mac operating systems. Disk Image Files are only meant to be used in Mac based systems and not on the Windows operating systems. However, using some image softwares like Daemon tools on windows, we can mount disk images of DMG type on windows too. Some tools can also convert DMG Files to windows-recognizable image files like .ISO files.

Benefits of DMG Disk Image format

DMG Images are read only which ensures that the files inside the installer are not altered with. This makes the software supplied inside the dmg secure from viruses as no one can alter the file after it is created.
Instead of sending more than one file over the internet, the creators have to send a single dmg disk image which contains all the required installation files of the software that can be simply dragged and dropped into the applications folder of Mac to install them.
DMG files can be customized according to the manufacturer’s wish so that the installers look pleasing when people download the files for installing software.
Disk images can be mounted on a computer just like a physical cd. This is a good thing as people can save a copy of the DMG file as a backup which can be used later to restore the previous state of the files.

What is ISO File

An ISO file stands for International Organization for Standardization file format which specified ISO as the standard file format for disk image files in Windows. It is a file which can be used to mount disk image files in Windows operating systems. It can be used to emulate a CD, DVD or any other disk drive in Windows virtually.

It is generally used to hold disk images of operating systems like linux which can be burned into a disk or a USB drive. It is also used to send installation files of Windows softwares through the internet but they are usually sent through a binary package with an executable or an msi installer.

Basically ISO files are an image of something so you could have an image of a computer software package that would be all the files that existed on that computer software in one finite image. You can also burn that image file to a CD because these are optical images.

How to Convert DMG File to ISO

The ISO file format can be used on the Macintosh operating systems, however, almost all of the software packages for Mac is downloaded from the internet as a DMG Disk Image file. Although the DMG file format has some features which are not available in the ISO format like file encryption methods and compression algorithms, DMG files cannot be used anywhere else instead of a Mac. This is why we may need to convert DMG FIles to the ISO File format.

To convert dmg to iso file on Windows, you should install third party softwares like PowerISO. It is a disk image burning software that can be used to convert DMG File to ISO on Windows. You can also directly burn DMG Files to a CD/DVD using this software.

Before downloading PowerISO, check the system requirements that is required to install and run Power ISO.

PowerISO can be used in both 32-bit and 64-bit versions of windows.
Processor: Intel Pentium with 166 MHz clock speed or better.
64 Megabytes of RAM.
A minimum of 128 Gigabytes of storage space is required to install and run PowerISO.

Steps to download PowerISO on Windows

Visit the official website of the PowerISO.
Go to the download section of the website
Select the version 32 bit / 64 bit according to your computer.

Now, an installer file will be downloaded on your computer, open the file and do the required steps to install PowerISO on your computer.

To convert DMG to ISO, first open the PowerISO application on Windows and then select the tools option from the top ribbon.

From the dropdown list, select the option labeled as convert. Now you will see a dialog box titled convert image file. You can use this to convert image files from one file format to another. In our case, we have to convert it from dmg file format to iso file format so we will set it up accordingly.

Now, we have to select a source image which will be your dmg file you want to convert. After that, select the destination image file and name it as the name of the iso file you want at the end. Below that, there is a drop down menu where you have to select the output file format, select iso file format there.

After that, there are image file settings options where you can password protect the images but since we are converting dmg file to iso, iso doesn’t have password protection options so that section is greyed out.

Now, select OK to start the conversion process. Wait for a few minutes for the conversion to complete. When the conversion is complete, you should get a message which says “Converting image file completes successfully”. If there is an error, check whether the input dmg file is corrupted or not. If there are no errors, go to the location of the output file you specified earlier, you should have an iso output file of the name you have given.
