Apple’s new operating system for Mac, macOS Sierra, launches this fall as a free download for most users.
If you want to try it early, you can get the public beta now and test all the new Sierra features immediately. Warning! You’ll likely encounter some bugs, so I don’t recommend installing Sierra on your primary Mac.
So what’s changing? Check out the most important Sierra features below.
That means desktop files will appear on all devices you're logged into, including Macs, iPhones, and iPads.
See? That photo of LeBron I saved to the desktop immediately appeared on the iCloud Drive iPhone app.
For example, search 'cat' and get all your cat photos.
The app will also group photos into albums automatically based on location and the people in them. Click on the Memories tab to view.
Apple does all its image recognition on your device and doesn't store your data on its servers.
It will remove files like iTunes videos and other large items and store them in iCloud. You can download them again later.
Apple says this will save several gigabytes of space for many users.
You can play videos in a picture-in-picture window on your desktop. It works with web videos and iTunes. Click the the special icon on the video player...
This feature only works with web videos you watch in Safari. You can't use it with Chrome or Firefox. So far, only ESPN and Vimeo have enabled picture-in-picture video, but there's nothing stopping YouTube and others from adding it too.
Apple says most app developers won't have to change their code to use this feature. It will happen automatically in Sierra.
iMessage on Mac is getting a lot of new features, just like it is in iOS 10. For example, emojis are three times larger. You can also react to messages with stickers.
The rest of iTunes pretty much looks the same as before, unfortunately. iTunes is long overdue for a redesign.
The notifications window has a new look. Widgets now appear in the Today tab, and you can customise them as you see fit.
But this is the biggest change: Siri is now on the Mac. You can do a lot with it, like search for images.
You open Siri from the icon in the dock or the taskbar.
Here's the result when you ask for audio files, but you can search for documents, photos, and everything else.
That's not all, of course. Searches are pretty much the same as they are on the iPhone.
But sending messages or emails with your voice isn't much easier than just typing them the old-fashioned way.
This is a useful way to find settings that are buried in a lot of menus.
There are a bunch of other features coming to Sierra that aren't live in the beta version yet. On top of everything you just saw, you'll also be able to use Apple Pay to shop in Safari (if the retailer supports it), unlock your Mac without a password if you're wearing your Apple Watch, and copy/paste items between your iPhone and Mac.
