OS X 10.9 Mavericks

OS X (pronounced OS ten) is the tenth major version of Apple’s operating system for Macintosh computers. It’s an OS known for its ultra cool design and intuitive graphical user interface. Believe it or not it’s a Unix variant — an OS universally known to be a command line savvy. Can you see the point? OS X has culminated the robustness of Unix and the aesthetics of GUI, yielding a perfect environment for personal computing.


OS X was the successor to Mac OS 9, released in 1999, the final release of the “classic” Mac OS, which had been Apple’s primary operating system since 1984. Mac OS X v10.0 “Cheetah” released in March 2001. All consumer releases of OS X up to 2013 were named after bit cats. OS X version 10.0 through 10.8 had been named respectively Cheetah, Puma, Jaguar, Panther, Tiger, Leopard, Snow leopard, Lion and Mountain Lion.

OS X’s core is a POSIX compliant operating system built on top of the XNU kernel, with standard Unix facilities available from the command line interface. Apple has released this family of software as a free and open source operating system named Darwin. Later OS X introduced a number of new capabilities to provide a more stable and reliable platform than its
predecessor, Mac OS 9. For example, pre-emptive multitasking and memory protection improved the system’s ability to run multiple applications simultaneously without them interrupting or corrupting each other. OS X’ glossy Aqua interface brought a radical new UI with soft edges, translucent colors, and pinstripes redefining the user experience.

In June 2013, the tenth major release of OS X (version 10.9) was announced at WWDC.  And the code name of OS X took a new direction by naming it Mavericks, a surfing location in Northern California. Thus transitioning the names based on big cats to places in California. OS X Mavericks was a release with deep overhaul of underlying technology. It’s been engineered enhance the battery life with features like timer coalescing and app nap. Performance enhancements include compressed memory, a virtual memory compression system which automatically compresses data from inactive apps when approaching maximum memory capacity. Mission Control has been updated to organize and switch between Desktop work spaces independently between multiple displays.
