Installing OS X from a DMG file can be difficult. With leopard testing and development, many people are having troubles installing from the supplied binary. Here is how it can be accomplished.

Installing OS X from a dmg file format instead of a DVD/CD format seems challenging. Here is how it can be accomplished.

1. Burn it to Dual Layer DVD

OS X is too large to fit on a single layer DVD; however, many macbooks support burning dual layer DVDs. The media is expensive, but for many people this is the easiest option.

Burn it and reboot to it. The OS X will install.

2. Restore the dmg file to an external device

An external hard drive or an iPod in hard disk mode will serve as an excellent booting device as well.

– Copy your dmg file to your current apple desktop.
– In the Utilities Folder in your Applications Folder select Disk Utility
– Select your external device in the left column of the utility
– Click the Restore button
– Drag your dmg to your Source textbox
– Drag your device from the left column to the Destination textbox
– Click the Restore

You will lose any information you have in your external device in this process. After the dmg is restored to the external device, change your boot disk to this device and reboot.
