Apple Mac OS X 10.9 Mavericks
Mac OS X 10.9
SAN FRANCISCO–Apple announced the next version of Mac OS X today at the Keynote for the WWDC. Named Mavericks, Mac OS X 10.9 brings more iOS features into the fold including a quicker way to multitask, the Siri voice assistant, Finder Tabs, and several other features.
Apple says Mavericks will become available this fall, which is a departure from its release schedule from the last few years. Over the past few years, Apple has followed a fairly regular schedule for OS X releases, with the announcement of a new Mac OS in February, and then the release date announced during the WWDC keynote (with an actual release soon to follow). This year, there was no announcement in the early part of the year, but a report form Daring Fireball said that Apple had pulled developers from the OS X team to work on the big changes in iOS 7, pushing the Mac OS X release to later in the year.[source:cnet]
