DiskMaker X (was Lion DiskMaker) helps you to build a bootable drive from the official OS X installer app (the one you download from the Mac App Store). It detects the OS X Install program with Spotlight then proposes to build a bootable install disk and make it look as nice as possible. It’s the easiest way to build an OS X Installer in a few clicks! Then you can use the Install drive to fully re-install the OS on a freshly formated drive, or install it on your many Macs without re-downloading the full installer.
