Mountain Lion is the second release of OS X to be delivered via the Mac App Store. Like with Lion, users can create their own bootable USB key installer to use as a recovery disk or to install Mountain Lion on multiple Macs without needing to download the 4GB installer multiple times.

Ars Technica has an excellent walk-through using either the Disk Utility application that is included on every Mac, or the newly updated Lion Diskmaker app that automates the process of creating a bootable install key.

The biggest catch to the whole process is to make a copy of the Mountain Lion installer before actually installing Mountain Lion, otherwise the installer will need to be redownloaded from the Mac App Store.

Unlike most of America I sadly do not have a true high-speed option for internet at my house. Thus I bring my MBP to work and use this method to generate an install package for my iMac at home. It's really the only way to do multiple installs if you don't have a good internet connection.

Reminder: you MUST copy the package before the actual install, but it's easy.

The Lion Diskmaker link... well, the link isn't bad, I don't think, but the server it points to isn't happy...

Yay, I'm about 5 minutes too late since I already installed ML. Oh well.

You got lucky in my opinion.

Hi, sorry for the ignorance but does this method work for doing a clean install of ML and not just upgrading from an existing installation of Lion?
