Apple has announced that OS X El Capitan, the latest major release of its desktop operating system, will be available as a free update for Mac users.

According to Apple, El Capitan builds on the groundbreaking features and beautiful design of OS X Yosemite, refining the Mac experience with updates to window management, built-in apps and Spotlight search, and performance improvements to make everyday activities — like launching and switching apps, opening PDFs and accessing email— faster and more responsive.

“People love using their Macs, and one of the biggest reasons is the power and ease-of-use of OS X,” Craig Federighi, Apple’s senior vice president of Software Engineering says. “El Capitan refines the Mac experience and improves performance in a lot of little ways that make a very big difference. Feedback from our OS X beta program has been incredibly positive and we think customers are going to love their Macs even more with El Capitan.”
