Apple Announces macOS Sierra at WWDC
Goodbye, OS X. Hello, macOS. (Version: Mac OS X 10.12) The next-generation Mac operating system has a new name, macOS Sierra, but most of the same great features, with some extras to boot—everything from Siri and Apple Pay integration to iCloud Drive desktop access and picture-in-picture (an iPad feature we love and can’t wait to use on the Mac). http://9to5mac.com/2016/06/13/apple-announces-macos-sierra-at-wwdc
Like iOS 10, macOS Sierra officially rolls out in September, but developers can beta test the software starting now and a public beta launches next month.
