When upgrading Mac OS X 10.6.6 to Mac OS X 10.7 (Mac OS X Lion), you may want to consider making a bootable Mac Lion install DVD disk or USB boot disk before upgrading your systems just in case you need to refresh your computer in the future. Lion Diskmaker makes this possible without having to use the Mac Lion redeem code in the App Store.
Lion Diskmaker is an AppleScript based application that helps you say on your Mac volume licensing count. You also won’t need to have to look for the Mac Lion package in your Applications folder. When you launch Lion Diskmaker, it automatically starts finding the Mac Lion package and prompts you of the search result.
When it finds the disk image, it will allow you to choose a disk to have the Mac Lion install created. If you already moved it to another folder, click Select A Folder and specify where the exact location of Mac Lion’s install package is:
After you click choose, it will verify the disk image and will prompt you for choosing a target source (blank DVD or USB drive). If you want it on a DVD, click on “Burn A DVD.” If you want it on a USB drive, click on “Create a boot disk”:
Lion DiskMaker works only on Mac 10.6 or higher.
