​Create reminders with Siri

Of course, reminders you create in macOS will be shared with your mobile devices as well.

​Some Siri searches can be saved

Say you search for all the NCAA games coming up next weekend. You’ll notice a “+” in your Siri results. Click on that to add the search to your Today window, which slides out from the right hand side of the screen.

​Searches saved

There it sits, giving you weekly updates of upcoming games.

​Control music playback with Siri

If lifting your finger all the way to the function keys is too exhausting let Siri do the heavy iTunes lifting. Tell her to pause a song and she’ll pause a song.

​Siri can skip tracks too

Not only will Siri control playback, but she’ll also change tracks or play any artist you request.

​"Read that back to me"

Tell Siri to show you your new email and she’ll slowly read the subject line and sender of each one. Tell her to read the whole message and she’ll do that too.

​Universal cut and paste

Have you ever copied a link on your phone and wished you could paste it onto your desktop browser? Apple thinks you have, so it added universal cut and paste to Sierra.

As long as you have handoff configured on your iPhone and Mac you’ll be able to cut and paste text right from one device to the other.

iCloud syncing gets new features

You can now sync the contents of your Documents folder and your Desktop right to iCloud.

​Storage management

New storage management options appear as well. Click on the Storage tab in the About This Mac window. You’ll see a new Optimize option.

​Storage optimization

Optimization can move unnecessary files to iCloud, automatically clear the trash, and remove old files you don’t need.

​Photos gets an overhaul

The Photos app is boasting a lot of improvements that bring it in line with the iTunes version. The memories slideshows are featured on macOS now, allowing you to watch the simple presentations on a bigger screen.

​Photo searching

Searching through your photos has gotten smarter as well: Photos recognizes location and faces.

Photos by location

There’s a neat location option too–see where on the map you took a shot!

​Tabs galore

Tabs aren’t just for web browsers anymore: they’re in a lot of other macOS apps too, like Finder and Maps.

​iTunes overhaul

Apple is really pushing its Apple Music subscription service, so you’ll see the same view whether you’re a subscriber or not.

​Suggestions for subscribers

If you are a subscriber you’ll notice a new look on the Suggestions and Browse screens.

​Picture-In-Picture

You can do it on your iPad, and now you can do it on your Mac as well: picture-in-picture is finally here.

​PiP limitations

Unfortunately, there are a lot of limitations to Apple’s PiP system: it’s an API that websites have to add in order for it to work. Right now the biggest name to offer PiP is Vimeo, so don’t count on undocking those YouTube videos anytime soon.

​Messaging changes

Apple seems dead set on overhauling Messages with a bunch of features of questionable use. While not all of them have made the leap from iOS to macOS there are a couple that have, and they are definitely some of the better ones.

Videos, for example, can now be played inside the Messaging program itself.

​Bigger emojis

When you’re just sending an emoji as a response it will show up nice and large.

​Individual read receipts

Want to make sure one particular person is seeing your messages? Now you can turn on read receipts by person instead of across the board.

​Apple Pay on the web

Some websites are adding the ability for customers to check out using Apple Pay. Click the button at checkout, and you’ll use Touch ID on your iPhone to complete the transaction.

The number of stores is currently a bit limited–here’s hoping it grows with time.

​No more disappearing folders in Finder

Tired of sorting by name and having all your folders get mixed in with your documents? Those days are over with macOS Sierra.

Open up Finder Preferences, click on Advanced, and check the Keep Folders On Top When Sorting By Name option.

​Collaboration in Notes

A lot of work is done on the web, and that means an increased need for collaboration. Apple has added the ability to share Notes with other macOS and iOS users so that you can both collaboratively work on documents.

​Safari extensions exit the web, join the App Store

It hasn’t been implemented yet, but soon Safari extensions will leave their home on the web for greener App Store pastures.

​Unlock your Mac with your Apple Watch

Good news for owners of the Apple Watch: you can configure it to unlock your Mac when you come within a certain distance.

Hopefully you don’t have a Mac made prior to 2013, though: 2012 and older models aren’t compatible with the auto unlock feature.
