Learn all the ins and outs of El Capitan, Apple's Mac OS X 10.11 operating system. First, take a tour of the core interface elements—the menus, Finder, and Dock—so you can start working with files, folders, and applications right away. Then learn how to save files and find them again quickly, as well as use the core applications that come bundled with El Capitan (Mail, Calendar, Messages, FaceTime, iTunes, and Safari), and install new apps from the App Store. Finally, the course explores backing up your system, manually or with Time Machine, so you don't lose any important data.
