Apple details its latest desktop operating system: macOS Sierra

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. 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. For its part, macOS Sierra is set to release in the fall as a free upgrade.
