macOS Sierra brings the familiar features of Siri for iOS to the Mac with an attractive user interface, third-party integration and some interesting capabilities specifically designed for the desktop that are not supported on iOS. In addition to standard search queries, you can ask Siri to locate a specific document you worked on last night, add a meeting to your calendar, start a FaceTime call and more.
The Siri interface is interactive, letting you drag and drop items from search results into your documents.
You can even pin Siri searches in the Notification Center with live updating! Here's our quick video preview of Siri for Mac in action and a detailed overview of the supported features that Apple hopes will make you more productive.
