I just upgraded my two-year old MacBook Air to OS X El Capitan last week. For free. And it’s publicly available as a 6GB download on Wednesday through the Mac App Store for all 2009 Macs and later. (You’ll need 8.8GB of space to install.)
Unlike last year’s OS X Yosemite, the latest version of Apple ’s Mac operating system isn’t teeming with new features and a whole new look. Instead, El Capitan refines the things that matter most in a computer: how fast our apps work and how fast we can work with so many of them open. Even the name symbolizes the fine-tuning: El Capitan is but a peak within Yosemite National Park.
