The new ways MacOS Sierra works with your iPhone or iPad

Copy and paste between devices with Universal Clipboard

The Universal Clipboard is a very useful feature that many iOS users have probably been waiting for. With this tool, your clipboard functions partly in the cloud. Copy something on one device, then switch to another device and choose the paste feature, and the content will copy over as if you never switched devices at all.

Of course, the Universal Clipboard will probably come with some limitations. Not all content is optimized for mobile devices, so transferring between platforms may still be a crapshoot for formatting. However, for simple content — especially things such as text or single images — this is a great tool for cross-device work, collaboration, larger projects, and working on the go. We assume that you need a Wi-Fi connection for it to work, however, since it depends on iCloud to save and transfer content.

Apple Pay integration

With MacOS Sierra, you will be able to shop on your Mac and then pay for goods or services with Apple Pay. You can tell if any particular site supports desktop Apple Pay because it will showcase an Apple Pay button during checkout. And before you ask, yes, Apple Pay still requires fingerprint authentication, which is where the co-op play between Mac and iPhone comes in. If you choose Apple Pay, then bring out your phone and use Touch ID to scan your fingerprint (your Apple Watch works, too). Your mobile device and Sierra will have a brief conversation, and then you’ll pay for your purchase as normal.

One advantage of this setup is convenience. If you already use Apple Pay, then it’s easy to quickly pay for something with the same feature rather than choose a more time-consuming transaction option. Another advantage is security. You won’t be punching in any credit card numbers with this service, and neither Apple servers nor traditional hard drive storage will hold card numbers where they can be accessed. Apple has been quick to assure customers that it will not track your purchases, on Sierra or any other platform.

Unlock your Mac with Apple Watch

This is a smaller feature, but still nifty for Apple fans. The new Auto Unlock allows you to unlock your Mac via your Apple Watch. It works based on proximity, so just walking up to your computer should log you in. It doesn’t seem to turn your computer on for you, so you’ll probably need it to be in at least a sleep mode. However, automatic logins can still be particularly useful at work or school when you need to step away from your Mac for a bit but still want to keep your privacy and save some time logging in when you return.

Cross-platform upgrades

A number of announcements from WWDC 2016 apply not only to MacOS Sierra, but to both the MacOS and iOS platforms. This primarily includes changes to iTunes, iMessage, and Photos. These applications are receiving updates that will at least partially appear on both Mac and iOS devices.

This approach is possible because of Apple’s push to unify native apps on its operating systems. MacOS and iOS may be fundamentally different, but many applications that run on each are very much the same in terms of look, features, and file compatibility. That makes it relatively simple for Apple to push out an update the goes live on both operating systems.
