El Capitan OS X 10.11 Beta Developer 1

Apple at WWDC 2015 announced the next version of the operating system OS X El Capitan. The twelfth major update of the desktop platform for Mac computers was officially presented on Monday at an event for developers in San Francisco.


Now, contrary to tradition, established since the beginning of 2000, when new versions of OS X were named after the animals of the cat squad, Apple has decided to turn to natural objects. OS X El Capitan named in honor of a cliff in Yosemite national Park. OS X 10.9 Mavericks, as you know, was called by the name of big waves off the coast of California, last year’s OS X 10.10 Yosemite – in honor of Yosemite national Park.

A new version of the desktop operating system has not brought updates to the appearance of the operating system and limited to the improvements on the level of functionality. The main changes, which Apple began the story of El Capitan, touched the control Windows (split screen) and Spotlight searching. Now the user can make queries in natural language, and the function became much faster. By optimizing the performance of the new operating system, Apple has risen to 1.4 times.

Apple moved to Mac Metal technology, which was introduced last year in iOS 8. This is a specialized API which is similar to AMD’s Mantle and Microsoft DirectX 12 avoids layering of standard graphics API OpenGL ES for games and applications for a more direct interaction with the hardware. According to Apple, the use of Metal will allow up to 40% increase in drawing speed.

El Capitan OS X Developer Preview will be available for developers and ordinary users with today. The final version will be released this autumn and will be distributed via the Mac App store. Download OS X El Capitan will be free to all Mac users.
