OS X 10.11 El Capitan is the latest version of Apple’s desktop operating system for Macs. Apple unveiled the new operating system on Monday at its annual developer conference in San Francisco. EI Capitan features include a new “pinned sites” feature that will allow you to pin your favorite websites you visit most often for quick access. The company has cited some significant number of features on the performance front, including apps and PDF files opening faster than before and switching of apps is twice as fast as we are experiencing with Yosemite.
