macOS Sierra does even more for you, so you can do more with your Mac. It helps you rediscover your best photos, work more seamlessly between devices, and free up valuable storage space. It also brings fun new ways to create super expressive messages. And now the files on your Mac are always right at your fingertips — whether you’re on your Mac, iPhone, or iPad.
Coming this fall
Rediscover memories in beautiful new ways.
You’ve spent years capturing moments worth remembering. Now Photos can turn them into unforgettable experiences called Memories. And powerful new technologies make Photos even better at face recognition, let you display all your photos on a world map, and even allow you to search your photos by the objects and scenery in them.
Get instant access to your Mac when you’re wearing Apple Watch. Just wake up your Mac and you’re ready to go. Take a quick call or step away, then get right back to work. No password typing required.
Copy on one device. Paste on another.
Copy images, video, and text from your iPhone. Then paste to your nearby Mac — or vice versa. There are no extra steps. Just copy and paste as you normally do. Find a great recipe while browsing on your Mac? Paste the ingredients right to the grocery list on your iPhone.
Your Desktop and Documents folder. Accessible on all your devices.
Now your Desktop and Documents folder — where most files are saved — can be automatically stored and updated in iCloud Drive. So you can always access them, including on a second Mac. No more wondering, “Where did I save that?” The answer is everywhere.
When you need more space, let your Mac find it for you.
Storage space maxed out? No problem. macOS Sierra can help make more room by automatically storing rarely used files in the cloud and keeping them available on demand. It can also help you find and remove old files you no longer use. So there’s always room on your Mac for new files and the ones you’ve used most recently.
Files you rarely need are saved in the cloud. Until you need them.
When you need more space, Optimized Storage makes room by storing infrequently used documents, Mail attachments, and photos in the cloud. Files you've used recently always remain on your Mac along with optimized versions of your photos. You can easily find every file right where you saved it. Just open it up and download the original as if it was always there.
Easily get rid of duplicate and obsolete files.
macOS Sierra can keep unneeded files from cluttering up your Mac. It reminds you to delete used app installers, and clears out duplicate downloads, caches, logs, and other unnecessary stuff. So you can be free of junk. It will even get rid of it for you, deleting items that have been in the Trash for 30 days.
Liven up the conversation.
Express yourself in fun new ways. Send a huge emoji. Respond back with a heart or a thumbs-up on a friend’s message bubble. And play videos and preview links right in the conversation.
Get all your docs in a row.
Now it’s easy to keep windows from piling up on your desktop. Tabs work just as they do in Safari — but now they work in almost every app on your Mac, and in many third-party apps as well. Just update to macOS Sierra and your apps are good to go. Breeze between multiple Pages documents in full screen. And look at lots of different destinations in Maps without getting lost.
Picture in Picture
Keep one eye on what you’re watching and the other on what you’re doing.
Now you can float a video window from Safari or iTunes over your desktop or a full-screen app. Play the video in any corner of the desktop and resize it to see more or less of what’s behind it. So you can catch up on your favorite show while you catch up on email. Or watch the big game while playing a game yourself.
