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.
Create a link/shortcut to /Applications folder by right-clicking on the Applications folder and selecting Make Alias then drag it into the dmg folder or from Terminal: cd /Volumes/myapp/ ln -s /Applications Applications In Finder press CMD+1 to switch to icon view and arrange icons as needed. I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format. File says my dmg file is a VAX COFF executable.
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.
