Why DMG Files Are Created?

Earlier, Mac applications made use of Resource fork. These are the part of file system on Mac Operating System, which consists of both the structured data and non-structured data. Mac could not transfer these Resource forks over the mixed networks. Hence, the usage of Resource fork dwindled and this was the reason that Apple created disk image formats(DMG). The Resource forks are very important as they contain Meta data regarding the file.

Mounting and Dismounting on Mac OS

It is equivalent to plugging in a removable drive, where E drive is automatically created and while removing one chooses ‘Safely Remove Device’. Similarly, you have to eject the Mac drive for both the virtual and physical.
Two Disk Formats supported are:

  • NDIF
    This was previously used as the default format of Mac, also known as New Disk Format. These files generally have an .img file extension.
  • UDIF
    The native disk format of Apple Mac DMG file is UDIF (Universal Disk Image Format) with a file extension of .dmg.

MIME Type of DMG File:
application/x-apple-diskimage.

Supported File Systems

  • Hierarchical File System (HFS) – This was developed by Apple Inc. for the systems supporting Mac OS. Earlier, these file systems were used in floppy disks and hard disks but later were used to read CD-ROM as well. It is known as Mac OS Standard.
  • HFS Plus – It was developed after HFS, which is an extension of the same. It is known as Mac OS Extended.
  • File Allocation Table (FAT) – It is a file system generally compatible with all file systems and helps in exchange of data between systems.
  • ISO9960 – This is also a file system which was issued by ISO (International Organization for Standard) supporting various OS and helps in exchange of data.

  • The DMG File consists of an application file. You can simply drag and drop to install them. If there is a possibility of having an installer, you can run these files instead of installing.
  • Right-click on the File >> “Eject” (click on virtual disk instead of, original file)
    Delete the old DMG Files after installing. The reason is old files may take more space when we install new programs.
