How do I download OS X El Capitan? That's the question we've heard many times since WWDC earlier this year. This morning Apple flipped the switch for OS X El Capitan, allowing users around the world to access their newest operating system. This version of OS X brings a revamp to a number of core apps - Maps and Spotlight in particular. Battery performance will be given a kick in the pants, as will processing performance. This update is all about refining and improving what was released with OS X Yosemite last year - and it's a solid update you'll be glad you initiated.
