Mountain Lion | featured news

A dog chased a cat up a tree Tuesday morning in Los Altos. Normally that wouldn't be a big deal, but this cat is a rather large mountain lion.

Apple's got a new big cat on the prowl. Its name is Mountain Lion, and it's the next major release of Mac OS X. The software is being released as a preview to Apple developers today, with a commercial release to follow sometime this summer through the company's Mac App Store. Like Lion before it, Apple has imbued the new software with many of the top-billed features from the iPhone and iPad, all with the intent of making its computers more useful and approachable to the millions that have snatched up an iOS device in recent years. It's also a direct response to recently-added features on those devices that--for better or worse--make the Mac a less essential piece of the puzzle.
