You can also use Apple Pay in Safari, unlock your Mac with your Apple Watch, keep all your Mac's desktops and documents in sync, and use all the cool new iMessage features that iOS 10 already sports, among other things. Another great one is the ability to copy/paste between your iOS 10 device and Mac. Siri is definitely the most tempting feature in macOS Sierra, which is more powerful than its iOS equivalent. While it hasn't gotten as much attention as iOS 10, Apple's big 10.12 update to their Mac operating system is finally out for all to enjoy-and you can download it for free from the Mac App Store right now.
