description OS X Lion Overview

OS X Lion was a controversial release that introduced Launchpad and Mission Control, attempting to bridge the gap between touch-based interfaces and the desktop. It was the first version to be distributed primarily via the Mac App Store. Today, it is completely obsolete and insecure. It lacks the modern security patches and software compatibility required for any functional use.

It is only of interest to collectors or those maintaining vintage hardware that cannot be upgraded further.
