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.

Dragging the source and destination files can be a little confusing. Click the picture below for a larger version.

What is a DMG file?

A DMG file is a mountable disk image used to distribute software to the macOS operating system. The file is typically downloaded from the Internet by a Mac user, then double-clicked to install an application on the computer.

Today, software developers typically build and distribute applications for Mac users as DMG, .APP, or .PKG files. DMG files are especially common since their contents can be verified upon installation to ensure they have not been tampered with and they can also be compressed to reduce the size of the installer.

When a Mac user downloads a DMG file, he can simply double-click it to open it with the DiskImageMounter utility that comes with macOS. When the DMG file is opened, it mounts a virtual disk on the desktop and in an Apple Finder window as if it was a CD or a USB flash drive that was just inserted into the computer.

In the Finder window, the Mac user can double-click the program icon, which is an APP file, to run the app. Or the Mac user can drag the program icon to the 'Applications' folder icon to move it to the 'Applications' directory in macOS. /cdr-to-dmg-software-windwos/.

After the software stored in the DMG file is installed, the DMG file is no longer needed. Therefore, DMG files can be deleted after installing the software.

While DMG files are Mac-specific and not intended for use in Windows, there are several Windows programs that can extract their contents or convert them to other formats. Some programs include 7-Zip, PeaZip, and DMG2IMG.

NOTE: The DMG format replaced the .IMG file format, which was previously used in Mac OS Classic.
