mountain lion - Computer Definition
Version 10.8 of the Mac OS X operating system. Introduced in the summer of 2012, and superseding Lion, many new features are included, some of which were pioneered in Apple's iOS operating system for the iPhone/iPad. For example, the iOS Messages function replaces iChat in Lion, and iOS Reminders, Notes, Game Center and central notifications are added. There is also more integration with Apple's iCloud online storage, and software updates migrate to the Mac App Store. The Gatekeeper function, which validates iOS apps when they are run in iPhones/iPads, makes its way to Mountain Lion, but in a less aggressive way, and it can be turned off. See Lion and Mac OS X.
