Apple's El Capitan Mac Software Ready for Downloads This Week

Apple Inc. is releasing its latest software for Mac computers this week, adding tweaks to the operating system to improve performance and streamline tasks.

OS X El Capitan, which will be available as a free update starting Wednesday, mainly works on Apple’s laptops and desktops sold since 2009, as well as some models stretching back to 2007, the Cupertino, California-based company said in a statement.

While the iPhone now makes up about two-thirds of Apple’s sales, the company’s roots are in personal computers. The PC industry as a whole has been shrinking, thanks to the popularity of smartphones and tablets. Yet Apple has been expanding sales of Macs. Apple’s shipments climbed 16 percent in the second quarter, making it the fourth-largest global PC vendor, according to IDC.

The name El Capitan comes from an imposing 3,000-foot tall granite rock formation in Yosemite, which is the code name for the current version of OS X. The new version is mainly a bunch of small visual enhancements on top of some basic rewiring of the software that will make it easier to create rich, detailed graphics.

“El Capitan refines the Mac experience and improves performance in a lot of little ways that make a very big difference,” Craig Federighi, Apple’s senior vice president of software engineering, said in the statement.
