Lion

(1) (LiOn) See lithium ion.

(2) (L10N) (L-ocalizatio-N) See l10n.

(3) Version 10.7 of the Mac OS X operating system. Introduced in 2011, it is a major upgrade with numerous enhancements as well as iPad-like features. For example, apps can be run from an icon grid like Apple's iDevices (see Launchpad); apps can display full screen, and they can resume where the user left off when re-opened.

Applications automatically save their data without user intervention, and the Mac's Exposé thumbnails of open windows and Spaces desktops were combined into one Mission Control function. The Mail app was redesigned like the iPad version, and new gestures were added to the trackpad. Befuddling users until they found out how to set it back the old way, the mouse scroll wheel direction was reversed to emulate trackpad movement.

No More DVD Installation
Lion was the first Mac OS version from Apple that was no longer offered via optical disc. Lion is available as a download or on a USB drive. See Mac OS X.
