Mac OS 10.9

Mac OS X used to be Apple’s bread and butter when it came to software, but thanks to the success of iOS over the past seven years, the Cupertino, Calif. company has been working hard to make its desktop and laptop operating systems mirror the mobile experience and popular features from iPhone and iPad, hoping to create one cohesive Apple ecosystem.
We don't know which big cat Apple plans to name this new Mac OS X build after, but we do know that Apple's been working on it for some time now: According to 9to5Mac, Apple began developing OS X 10.9 simultaneously with last year's OS X "Mountain Lion," which similarly sought to integrate more iOS features into the Mac experience, such as the Notification Center, Notes, Reminders, Dictation, and document syncing in iCloud. The Apple news site has also been tracking Mac computers running OS X 10.9 that visit its site since last year, and all of those computers are tagged with IP addresses from California's Bay area where Apple's headquarters is located.

In mid-November, 9to5 Mac's Mark Gurman said Mac OS X 10.9 will release with two of Apple's most widely used features from iOS -- citing “reliable sources” -- including its new self-branded Maps application, as well as Siri, the company's virtual personal assistant that first debuted on the iPhone 4S in late 2011.

With Apple expected to announce the next iterations of iOS and Mac OS X at WWDC 2013 next month, users are looking forward to seeing what iOS 7 and OS X 10.9 have to offer. While we’ve heard a great deal about the redesigned “de-Forstallization” in iOS 7, many consumers still want to know what’s coming for the next version of Mac OS X.
