With macOS Sierra, Apple, as with previous versions, integrates even more features that were introduced in iOS, the operating system for the company’s mobile devices. But Sierra doesn’t just add features found in iOS, it also does more to make your Mac and your iOS devices work together. Considering that nowadays, most people’s primary computers are iOS devices, it’s fitting that macOS Sierra does more to cater to those users’ needs.

Before we dive into Sierra, let’s address the main question: Should you upgrade? First, you need to determine how compatible your Mac is. The older the Mac, the more likely a feature won’t work. You can check a list Macs compatible with macOS Sierra. (Apple also has information on what features are available based on region and language.) Checking this first may answer the upgrade question for you.

You also need to see if your software will still work with Sierra. If your software worked with El Capitan, Yosemite, or Mavericks, there’s a good chance it will work with Sierra. Check with the developer of your most vital apps before your upgrade.

I’ve been using the public beta and the golden master version since it became available, and on the five Macs I’ve been using, I haven’t a single stability problem. That’s one less thing to consider.

Once you’ve determined that your Mac is compatible to a point you’re satisfied with and your software is good to go, then it gets a little more complicated. One way to look at it is to gauge how much you use iOS. If you use your iPad and iPhone a lot, then you’ll appreciate Sierra features like Siri, Universal Clipboard, and Apple Pay. Let’s take a look at the main new features of Sierra, and see how they fit into your workflow.

(And if you do decide to upgrade to Sierra, be sure to back up your Mac before you run the Sierra installer. Always back up before installing any operating system upgrades.)

Siri comes to the Mac

Siri, Apple’s voice assistant, is the marquee feature of macOS Sierra. It’s also the most obvious feature that signifies the iOS-ification of macOS.

When Siri is active, it works exactly as it does on iOS. However, there is no default setting to allow Siri to activate by saying, “Hey Siri” like you can on iOS. (You can get voice activation to work if you create a Dictation Command to trigger the Siri keyboard shortcut.) The default keyboard shortcut for Siri is to hold down Command-Spacebar, or you can click the Siri icons in the menu bar and in the Dock.
