Your MacBook products are about to change and get a whole new refresh. Apple revealed some updates to the OS X system at this year's Worldwide Developers Conference [1] — including a name change. Though it's not as exciting a change as El Capitan [2], some new features are coming. See what the updates to the new macOS Sierra [3] are ahead:

• A new name: The operating system is dropping the X and will now be called macOS to join the other operating systems: iOS, watchOS, and tvOS.
• Siri becomes the assistant you've always wanted: You can finally talk to Siri on your computer, and you can do it without touching anything. Just say "Hey Siri" and you're good to go.
• Using your computer becomes faster: If you're wearing an Apple Watch, your MacBook will automatically unlock when you're nearby and won't require a password anymore.
• iCloud syncing gets smarter: Ever move something to your desktop? You can now access that across all your devices.
• Copy and paste gets simplified: With Universal Clipboard, you can copy something on your iPhone and paste it onto your Mac, images, video, and more.
• Apple Pay is now available on the web: Now when you're shopping, you can select a "Buy With Apple Pay" button and continue the transaction with either your iPhone or Apple Watch and Touch ID.
• Picture in picture comes to macOS Sierra: Just hit the picture in picture button and you can keep watching your video.

You can download macOS Sierra [4] starting Sept. 20. Ahead, check out photos of some of the features.
