Dec 10, 2012  The OS X 10.8 Mountain Lion installer will fit on a Singe Layer DVD, if that helps. Thus you could use a goo Windows burning program to burn the DMG/ISO you. In Disk Utility, select InstallESD.dmg in the sidebar Click the Burn button in the toolbar. When prompted, insert a blank DVD (a single-layer disc should work, although you can use a dual-layer.
