What can your Mac do now? Just ask.
Siri makes its debut on Mac, with new capabilities designed just for the desktop. And that’s not the only way your Mac is smarter. macOS Sierra helps you rediscover your best photos, shop faster and more conveniently online, and work more seamlessly between devices. It can also help free up valuable storage space. Now your Mac does even more for you, so you can do more with your Mac.
