What is a DMG file and how do I open it?
The DMG format is a mirror file on a Mac system, or a compressed file, if you use a PC and don't have Mac OS X for X86, don't bother. If you are using an Apple or a Mac OS X for X86 on your PC, double-click the file on your Mac system to unlock it, and if you want to burn the file to a DVD, use Toast to burn the file to a disc: Dmg=>disc image
The command line creates the DMG
