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.
Nov 18, 2019 A DMG file is an Apple Disk Image file often used to store compressed software installers. You can open DMG files on Windows, Mac, and Linux. I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format. File says my dmg file is a VAX COFF executable.
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).
Sep 07, 2009 The problem is happening again. There must be something that resets the settings for this issue. I've also noticed this time around that if I mount a dmg manually with the Disk Utility, and contains an installation package, that it starts the 'Installer' utility, but it just bounces on the dock and becomes unresponsive to anything but a Force Quit.
