DiskMaker X is the successor to Lion DiskMaker. The tool creates a bootable DVD or a bootable USB stick for Mac OS X 10.7 Lion, OS X 10.8 Mountain Lion and OS X 10.9 Mavericks.
Apple provides Mac OS X 10.7 Lion, OS X 10.8 from Mountain Lion and OS X 10.9 Mavericks by default only on the Mac app store. Users need to download the software to upgrade from Snow Leopard or lion.
Users who want to install the OS on multiple Macs need a bootable media. The Lion DiskMaker tool does this job. It is suitable for creating a bootable USB stick of Lion, Mountain Lion, and Mavericks. Bootable DVDs can also be created.
