Apple Seeds Second Beta of macOS Sierra to Developers
The update can be downloaded through the software update mechanism in the Mac App Store or through the Apple Developer Center.
macOS Sierra is a major update that brings Siri to the Mac for the first time, allowing users to conduct voice searches to quickly find files, look up information, and more. New Continuity features offer an "Auto Unlock" option for unlocking a Mac with an Apple Watch and a Universal Clipboard for copying something on one Apple device and pasting it on another.
Deeper iCloud integration makes files stored on the desktop or the Documents folder of a Mac available on all of a user's devices, and Photos features new deep learning algorithms for facial, object, and scene recognition. There's a new Memories feature for displaying photo collections, and Messages has features like rich links, bigger emoji, and "Tapback" response options.
Apple Pay is coming to the web in macOS Sierra, with payments authenticated through an iPhone or Apple Watch, and new features like multiple tabs, Picture in Picture multitasking, and optimized storage are available.
