DMG file is used by Apple Mac OSX Disk Image files. Mac OS X natively support DMG files with the bundled AppleDisk Utility, and can mount and treat them as though they are physical diskvolumes. Mac OS Classic originally used the IMG file format for the samepurposes, though this has now been superseded by DMG format.
DMG files are similar in nature to otherdisk image files such as ISO in that they contain a folder and file structurewhich can be mounted and treated like a physical volume. As well as browsingthe contents of a DMG file, it can also be used as the source to create CD orDVD copies. However, DMG files can use a variety of different file systemsincluding HFS, HFS+, Linux and Fat32, and are usually compressed, which maymake them incompatible with other software on other operating systems such asWindows. DMG files are often used to distribute software in the same manner asan EXE file is used for the Windows platform, and may be password protected toprevent unauthorized users mounting and using the image.
You can open DMG file in Mac OS Xusing the Apple Disk Utility, which is bundled as part of the operating system.However, the DMG file format is new to OS X and as such is not compatible withprevious versions of Mac OS. DMG files are specific to Mac OS X, though can beopened in Windows using an application such as TransMac. Additionally, toolssuch as IsoBuster and DMG2ISO can be used to convert DMG files to more recognizableformats such as File extension ISO or File extension BIN, which can be opened using a wide range ofapplications or burnt straight to disc using software such as Roxio or Nero.
A DMG file is a mountable disk image primarily used to distribute software to the macOS operating system. Mac users typically download the file from the Internet and then double-click it to install an application on their computer.
The DMG format is one of several file types software developers utilize to distribute macOS applications outside of Apple's App Store. Other options include .APP files compressed in a .ZIP archive, .PKG files, and .IMG files (more common in Mac OS Classic and replaced by DMG files).
DMG is a prevalent distribution format because it maintains the disk image's integrity via checksums. When opening a DMG file to begin the installation process, the DiskImageMounter utility bundled with macOS verifies the checksum to ensure the disk image has not been modified or corrupted during the distribution. This process is valuable for developers and end-users to make sure they install an untampered application.
NOTE: In rare cases, Mac users may package files instead of macOS apps in a DMG file for transfer purposes. In these cases, the DMG file functions as a virtual flash drive recipients can mount to retrieve the stored files.
You can open a DMG file by double-clicking the file. After clicking the file, the DiskImageMounter utility bundled with macOS verifies the disk image's integrity. After confirming the disk image, the utility mounts the virtual disk and places it on your desktop and in an Apple Finder window as if it was a CD or a USB flash drive inserted into the computer.
You can double-click the program icon (actually an APP file) in the Finder window to run the app. Or, you can drag the program icon to the Applications folder icon in that same window to move it to the Applications directory on your computer, then double-click the app directly from the Applications directory to run it.
DMG files are Mac-specific and not intended for use in Windows. Therefore, if you download a DMG file from a website, check the site for a Windows version of the software (most likely distributed as an .EXE or .MSI file).
Although you cannot install software distributed via DMG files in Windows, several Windows applications can extract their contents, including 7-Zip and PeaZip. You can also attempt to convert the DMG file to an .IMG file with the DMG2IMG utility.
The FileInfo.com team has independently researched the Apple Disk Image file format and Mac, Windows, and Linux apps listed on this page. Our goal is 100% accuracy and we only publish information about file types that we have verified.
If you have trouble opening DMG files by double-clicking them, even if you have PeaZip or 7-Zip installed, try to right-click the DMG file and use the context menu. For example, 7-Zip opens DMG files via 7-Zip > Open archive.
Again, just because you can extract a DMG file in Windows, or even convert a DMG to a Windows-readable format, doesn't always mean that the contents of the DMG file will suddenly become compatible with Windows. The only way to use a Mac program or a Mac video game in Windows is to download the Windows-equivalent version. If there isn't one, then neither converting nor extracting a DMG file will be of any use.
I don't know why going to the frist website where I downloaded a .dmg did not create this entry in the application table, but it is there now so I can control the behavior in the future when I download .dmg files.
If you search for 'dmg' the the applications search box, you'll find .dmg files listed with "Use DiskImageMounter" on the right hand side.

Here are the simple steps you can take to mount .dmg file using iSumsoft Bitlocker Reader for Mac.
Native to the Mac OS X operating system, the DMG file format is often compared to the ISO file format because both formats can be used to create sector-by-sector copies of optical storage media. But despite the similarities they share, the DMG file extension was actually created with a different purpose in mind.
Back in the day, Apple struggled to find a way how to reliably transfer applications over the internet. They came up with DMG, a disk image format that can be structured according to one of several proprietary disk image formats. Unlike its brother from the Windows operating system, DMG files can be secured with password protection, and they make it possible to change the way their content is presented in Finder. Software developers often take advantage of these features to instruct users how to copy the application to the correct folder.
So far, Apple has not released any documentation for the DMG file format, but its implementation has been successfully reverse-engineered. The result of this effort is VileFault, a tool capable of decrypting encrypted Mac OS X disk image files.
File Extension DMG has two unique file types (with the primary being the Mac OS X Disk Image File format) and is mostly associated with 7-Zip (Igor Pavlov) and seventeen other software programs. Generally, these files are considered Disk Image Files, but they can also be Data Files.
Windows, Android, and Linux operating systems can be used to view DMG files. Both desktop and mobile devices enable you to view and (sometimes) edit these files, depending on the software used. DMG files have a "Low" Popularity Rating; this means that they are not present on most devices.
Although there is a lot more to know about DMG files, those are the most important details of these types of files. If you are having trouble opening these files, or would like more detailed information, please see our comprehensive information below.
Sometimes your installed version of 7-Zip won't support your Mac OS X Disk Image File file. If you've got the wrong version of 7-Zip installed, you'll need to install the correct version.
