This was created for those of you that would rather skip all the hassles of installing a fresh OS onto a newly formatted volume. This virgin OS has never been booted yet and will require you to create a user account. To restore this onto a Mac GUID partitioned volume: Use Apple's Disk Utility to restore it to a fresh volume or your favourite disk copying tool.

Mac OS X Lion (version 10.7) is the eighth major release of Mac OS X (now named macOS), Apple's desktop and server operating system for Macintosh computers. A preview of Mac OS X 10.7 Lion was publicly shown at the "Back to the Mac" Apple Special Event on October 20, 2010. It brought many developments made in Apple's iOS, such as an easily navigable display of installed applications, to the Mac, and includes support for the Mac App Store, as introduced in Mac OS X Snow Leopard version 10.6.6. Lion was released to manufacturing on July 1, 2011, followed by its final release via the Mac App Store on July 20, 2011. Lion is the final release whose development was overseen by Bertrand Serlet, considered the "founding father of Mac OS X".
