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.
DMG Extractor is a software that extracts DMG files from macOS to a format that is compatible to be read in Windows. macOS uses DMG files to verify that the downloaded files are secure and not tampered with. These are file containers for MacOS files and require a third-party extraction tool like DMG Extractor to be read in Windows.
DMG Extractor, like the name suggests, is a tool to extract DMG files for Windows. This is a read-only program, available for free or a premium version, that cannot create a DMG file but only reads it for Windows. It can be download and installed on Windows devices, and is ready to use by simply importing the DMG files. The interface is simple and fuss-free, and extracting DMG files is the only functionality it has.
Alternatives to DMG Extractor include Universal Extractor, HFS Extractor, TransMac, Free iOS Converter, 7-Zip, Rar Password Cracker, Mac Drive, and more. Many of the other competitors, including TransMac, 7-Zip, Universal Extractor, are a lot more comprehensive in what they can extract and are not limited to just DMG files.
One might argue that the functionality of DMG extractor is a niche for the purpose it serves, and does not complicate too many tasks in one program, however, it is mostly the case that people prefer to download a single program for many functions, rather than multiple programs to perform each function. This is where DMG extractor is vastly limited. In all probability, simple extraction programs like 7-Zip will be able to open the DMG files, but if it does not, that is when one needs to use DMG Extractor. The same is not true for the other way round, as there is very little DMG Extractor can do that 7-Zip cannot or Universal Extractor or TransMac cannot.
DMG Extractor is quick and easy to use, with a simple interface and features. One needs to simply import the DMG files on to the software, and run the extraction, for them to be readable on Windows. The extracted files can then be stored at a preferred destination. DMG is basically the format used by macOS to archive the files, and DMG Extractor is a third-party program that can decompress these files to be accessed individually on Windows. Since DMG files cannot open directly on Windows, this is a really good tool to have.
As mentioned earlier, while DMG Extractors serves its purpose of extracting DMG files on Windows, a number of other programs do that for a lot more than just this format. DMG Extractor is basically a read-only program that can extract the files but not create new DMG files on Windows, and it cannot extract files from any other formats. Compared to this, other programs like 7-Zip, Universal Extractor, and more, are able to extract files from other formats like .zip, .rar, etc, as well.
The DMG Extractor can extract DMG files as used by Apple computers on a Windows PC. The software works with all types of DMG files including Raw, Zlib, Bzip2, and Zero block type DMG files. You can view all files with in the DMG in a simple to use file system set-up and choose various option to extract the files quickly.
The DMG Extractor can open a wide variety of Disk Image files as used on OS X, without having to first convert them to ISO or IMG files. Easy to use software, no technical knowledge requiredNo spyware or adsPowerful free version
An Apple Disk Image can be structured according to one of several proprietary disk image formats, including the Universal Disk Image Format (UDIF) from Mac OS X and the New Disk Image Format (NDIF) from Mac OS 9. An Apple disk image file's name usually has ".dmg" as its extension. A disk image is a compressed copy of the contents of a disk or folder. Disk images have .dmg at the end of their names. To see the contents of a disk image, you must first open the disk image so it appears on the desktop or in a Finder window.
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 (HFS+), File Allocation Table (FAT), ISO9660, and Universal Disk Format (UDF).
Apple Disk Images can be created using utilities bundled with Mac OS X, specifically Disk Copy in Mac OS X v10.2 and earlier and Disk Utility in Mac OS X v10.3 and later. These utilities can also use Apple disk image files as images for burning CDs and DVDs. Disk image files may also be managed via the command line interface using the hdiutil utility.
An Apple Disk Image allows secure password protection as well as file compression, and hence serves both security and file distribution functions; such a disk image is most commonly used to distribute software over the Internet.
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", intended only for Mac OS 9 and earlier.
Apple disk image files are essentially raw disk images (i.e. contain block data) with some added metadata, optionally with one or two layers applied that provide compression and encryption. In hdiutil, these layers are called CUDIFEncoding and CEncryptedEncoding.
The encryption layer comes in two versions. Version 1 has a trailer at the end of the file, while version 2 (default since OS X 10.5) puts it at the beginning. Whether the encryption is a layer outside of or inside of the blkx metadata (UDIF) is unclear from reverse engineered documentation, but judging from the vfcrack demonstration it's probably outside.
Most dmg files are unencrypted. Because the dmg metadata is found in the end, a program not understanding dmg files can nevertheless read it as if it was a normal disk image, as long as there is support for the file system inside. Tools with this sort of capacity include:
Memories are everything one person has got. Some people capture the memories in the form of images to relive the moments of joy whenever they want to. Images have different formats as aJPG file, DMG file, or other formats depending on the user's device and version.
A DMG file stands for Disk Image File. Any file with the extension of ".dmg" is an Apple Disk Image File. This image format is commonly used by macOS operating system. It is also referred to as a macOS X Disk Image file that is a digital reconstruction of a physical disc. Mac users from the internet usually download the file, and then an application can be installed by double-clicking it.
