In case Siri coming to macOS wasn't enough for you, Apple Pay is joining the virtual assistant on desktops and laptops. That means you'll now be able to use the service on the web, making it faster and simpler to check out on some of your favorite shopping sites. Meanwhile, to help with productivity, macOS Sierra will feature a picture-in-picture mode, similar to what we've seen on the iPad.

Without a doubt, the biggest announcement is Siri expanding outside of iOS. In macOS, the virtual assistant lives on the familiar desktop dock, right next to the Finder application. Functionality-wise, Siri for macOS can control apps and do web searches -- and tell you jokes, of course, because we all know how important that is. It's available today in public beta.

For its part, macOS Sierra is set to release in the fall as a free upgrade. According to Apple, the operating system will be compatible with late-2009 and later MacBook and iMac, as well as 2010 and later MacBook Air, MacBook Pro, Mac mini and MacPro.
