Today OS X 10.10 Yosemite will be coming to your Macs. The OS, which includes a new iOS 7 inspired user interface, iCloud Drive, and Continuity support with your iPads and iPhones will be available to download from the Mac App store later today. It’ll work on any Mac 2009 and newer and select Macs from 2007 and 2008. Yosemite will not cost you a penny. The update is completely free.
Apple also announces that for iOS users, iOS 8.1 will launch this Monday, October 20th. There will be several new features including Apple Pay and the return of the Camera Roll which was absent in iOS 8.0. iOS 8.1 will also include the public beta of iCloud Photo Library which will store all your photos at full resolution in iCloud Drive. After what happened with iOS 8.0.1, make sure there are no issues before you upgrade.
