OSX Yosemite Available to the Public
Apple’s latest desktop operating system, Yosemite, is available today as a free download in the App Store for anyone with a reasonably new (or not-so-new) Mac. OS X Yosemite comes with a redesigned look and feel to bring the OS aesthetic more in line with iOS, as well as several groundbreaking new features like iCloud Drive, Continuity, revamped Spotlight, widgets for Notification Center, and more. Notably, however, some of these features require newer hardware.
With any update to the operating system please be sure to backup all your info prior to updating.
