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.
OS X El Capitan is available as a free update starting Wednesday, September 30 from the Mac App Store. El Capitan supports all Macs introduced in 2009 and later, and some models introduced in 2007 and 2008.
