Apple TV keeps getting better and
better. With the tvOS update, Siri can now search for specific topics. Single

even control the house lights and adjust your thermostat right from your TV. 
In

sign-on to sign in to all apps at once, a smarter Siri with third-party app
integration, a Dark mode, and more.
macOS Sierra offers new features that
includes the ability to use Apple Pay, the company’s mobile payment option,
from within Safari for partners that include Gilt, and other major brands. With
it, users will be able to authenticate purchases on their desktop by using
Touch ID on their iPhone.
macOS offers other new Continuity
features, too, including the ability to unlock your MacBook –avoiding the part
where you input your password– by having your Apple Watch on your wrist.
The biggest new addition for macOS
Sierra is Siri, which lets users ask the digital personal assistant to do a
variety of things, like find files, contacts, and use more complex voice
queries to find specific elements on their computer from specific dates or from
other people. Siri can also play music from Apple Music, send messages, and
much more.
Apple plans to release all this beta
version to public in July, and will release its full update this fall.
