8 Reasons You Should Use Apple's New iPhone Mirroring Feature on iOS 18 and MacOS Sequoia

When Apple revealed the new iPhone Mirroring feature in the upcoming iOS 18 and MacOS Sequoia releases at WWDC 2024 earlier this year, I was pretty impressed by the tech. 

From your Mac, you can remotely view and control your iPhone, even if the phone is at the bottom of a bag or in another room. But… why?

Setting aside the reality that my iPhone is almost never that far from me, what benefits are there for connecting to it via my Mac? It seemed more like a feature introduced because the tech is there, not really due to an urgent need from Apple owners.

However, after using the new feature in the iOS 18 developer and public betas, I've had some time to get to know iPhone Mirroring and come up with eight ways it can be genuinely useful -- and one scenario that would be great but is currently limited.

If you want to try iOS 18 yourself before it's released to the general public, here's how to install the public beta (and why you should be cautious and install on a test device). The public beta program also gets you access to the prerelease version of MacOS Sequoia (the other piece you need for iPhone Mirroring to work), as well as Apple's other upcoming system updates. 

Also, here's how to follow along with Apple's big event on Sept. 9.

When your iPhone is in a bag, purse or another room

The easiest use case is when you want to access something on your phone but it's buried in a bag, just out of reach or you're unable to get up (or you are able, but the snoozing cat or dog on your lap wouldn't appreciate the disruption). Connecting via iPhone Mirroring is much more convenient.

However, this feature doesn't work over long distances, like if you accidentally left your iPhone at home and you need to access it from work. iPhone Mirroring uses Apple's Continuity technology to work, which means the iPhone and Mac need to be within Bluetooth range of each other.

When you need to check in on an iPhone app

Did you miss your daily Duolingo check-in and the phone isn't handy? If your Mac is, iPhone Mirroring can connect and make sure you keep your streak going.

Or maybe you need to finish today's Wordle challenge but it would be too obvious while working that you're checking your phone. The discreet iPhone Mirroring window can be easily covered or hidden if necessary.

When you want to use an app, not a web interface

Even today, some popular services work far better in apps than they do as web interfaces. Yes, we're looking at you, Instagram. Posting from an app often includes more options or a better user experience. Since iPhone Mirroring gives you almost full access to the iPhone's interface, you can post using a mouse pointer instead of a finger.

When you want to transfer items quickly between devices (later this year)

I create a lot of screenshots for work and take even more photos personally, which all end up in my Photos library. Those images are then synced via iCloud to my Mac -- but sometimes it seems at a pace accurately described as "when the phone gets around to it." When I need something on my Mac right away, I find myself using AirDrop between devices, which works but is clumsier than I'd prefer.

Later this year, though, we will be able to drag and drop all sorts of files -- not just images -- between an iPhone and the Mac running the iPhone Mirroring app. That will go in both directions, too: Drop a video or important PDF from a Mac Finder window onto the mirrored iPhone to transfer it to the phone.

When you don't want to clutter your Mac with software junk

MacOS has a long legacy of supporting system extensions, startup items and various background processes that you probably don't realize are running most of the time. Some large application suites, for example, spread out these accessory files like a dropped box of Legos. In many cases, the drain on resources is negligible, but those pieces still consume storage and processor power.

In contrast, iOS has always been built as a silo'd system, where each app has its own protected storage and strictly controlled routes for interacting with other apps. Especially for apps you don't use often but need to keep around, you may want to install a mobile version and avoid the app creep that happens under MacOS.

iPhone Mirroring gives you a way to still use an app like this on your Mac, without infecting MacOS with all the associated detritus that is normally installed.

When you want to sign in to your bank's app instead of doing it on the computer

Sadly, several of these suggestions focus on the theme of "an app is better than a website," and there's often no greater example than banking sites.

It can be easier, and more secure, to access your bank accounts or investments using iPhone Mirroring to log in with the iOS app instead of a web browser on your Mac. You still need to authenticate the iPhone app when you open it (since you can't use Face ID or Touch ID on the device), but that could be a more convenient option.

When you want to access locked and hidden apps on your phone

In iOS 18, you can hide sensitive apps or require authentication (such as Face ID) to open them. If you'd rather use them on your phone than through an app or web interface on your Mac, iPhone Mirroring lets you access them when the phone isn't nearby.

When you do, the iPhone Mirroring app requires authentication via the Mac, as you would expect. Enter your Mac's login password to open locked apps or make the Hidden folder on the phone visible.

When you're giving a presentation and want to show what's on the iPhone

Granted, this is a smaller subset of use cases, but if you need to demonstrate something on the iPhone during an online or in-person presentation, iPhone Mirroring is a far easier option than other methods.

Aside from rigging an overhead camera, the prevailing method has been to connect the iPhone to a Mac with a cable and use QuickTime Player to view the phone's screen. You'd then still need to operate the phone with your hands.

Now with iPhone Mirroring, the phone can be connected wirelessly and manipulated using your Mac's trackpad or mouse and keyboard.

The main limitation with this approach is that if you do need to perform something on the phone, activating it pauses the mirrored connection.

And one streaming limitation we'd like to see changed

One unheralded feature between Apple devices is the ability to stream media from an iPhone to a Mac using AirPlay. Time to kick back and watch a movie or take in an episode of your favorite TV show? You can start it on the iPhone and choose the Mac -- with its larger screen -- as the destination.

Since iPhone Mirroring lets you control an iPhone that's out of reach, it would be nice to start a movie that plays on the Mac's screen. Unfortunately, digital rights management squashes that idea in the context of iPhone Mirroring. Although you can open an app such as TV and tee up a show, the image remains black.

That black screen also applies if you use AirPlay to stream while iPhone Mirroring is active. The only way this works is if you control the phone physically and stream to the Mac.
