Siri’s look for OS X 10.12 has been leaked via screenshots surfaced by Macrumors. Siri’s new desktop Dock icon features a voice wave pattern, similar to its iOS version. It will also be accessible from the menu bar, with a button placed next to the notification center.
Siri on OS X would support the same features as it does on iOS: HomeKit control, searches, sending and reading messages, emails, notifications, Twitter and Facebook support and more. It will be interesting to see as to which extent does Siri on Mac support system features and toggles as they really out number the ones on iOS. Siri will also support hands-free Hey Siri. Whether this will require any particular hardware as it does on iOS devices is yet to be seen as hands free Hey Siri only works on the latest devices when unplugged. Older devices only listen to Hey Siri when they are plugged in to a charger.
WWDC 2016 will start on June 13 and it is expected that Apple will officially share details on the next OS X, iOS, watchOS and tvOS updates.
