Apple‘s new Macintosh operating system, OS X 10.11 “El Capitan,” is named after a prominent rock formation in Yosemite National Park. That’s fitting because the new OS is designed with rock-solid stability in mind. El Capitan is the 12th iteration of the OS powering Apple’s desktop computer lineup, and as the name implies, it stands on the shoulders of its predecessor.
Just as iOS 9 was built on the foundation laid by iOS 8 for mobile devices, El Capitan improves on the many changes introduced in 2014’s Yosemite — which included new features such as Continuity and a smarter Spotlight search tool. El Capitan adds more polish than features, though there are quite a few of those to explore, as well.
