DMG files are a Mac OS X Disk Image files. like ISO files, DMG files are essentially disk images, which are intended to be used with the Mac operating system. The DMG files normally contain program installation files for Apple system and applications, but they can also be used to hold compressed files.

    Click 'Browse' button to select the DMG file you want to burn.

    Select the burning drive and the burning speed from the list. The default burning speed is maximum speed supported by the writer and media. You can change it to a slower speed if necessary.

  • PowerISO will start burning the dmg file to the disc. You can see the detailed progress information during burning. If no error occurs, you should see the message, 'Burning completed successfully.' at the end of burning.
