UPDATE 07.26.12 – Thanks to commenter Benoit’s comments, you can now burn a single-sided/single-layer DVD. You MUST have a dual-sided DVD in order to burn the DVD. NOTE: The expanded size of the Mountain Lion installer will NOT fit on a single-sided DVD. So, if you do want to create an installer DVD (and you could do this with a USB drive as well), here are the steps to do so. But what if you want to install Mountain Lion on another computer (that is supported)? There is a way to easily do this, but remember, you should only do this with computers that you own or manage (and you wouldn’t need to do this if you had all of your computers use your Apple ID in the App Store – you would just install right from there).

(I put a copy into another “backup” directory) I would suggest making a copy of this file, and making a backup for it, just in case something goes wrong. Right click (or Control + Click) the installer and select “Show Package Contents”, and navigate to the “Shared Support” folder, where you will find the installer “InstallESD.dmg”.
