Poll a room of Apple experts about the one topic they can’t stop talking about and many will launch into frustrated rants about how too few people back up. Backups are always important, since you can never predict when your Mac or iPhone will be lost or stolen, melt in a fire, or just break. But one time when backups are especially important is before you upgrade to a major new operating system. If you’re thinking “What could go wrong?” the answer is, “Lots, and wouldn’t you like to be able to revert instantly if something does?”

Mac Backups

On the Mac side, backing up with Time Machine ensures that you can not only restore your entire drive if necessary, but also easily recover a previous version of a corrupted file. Also, since a fire or flood would likely destroy your backup drive along with your Mac, we always recommend an offsite backup made via an Internet backup service like Backblaze.

What happens if you don’t back up and your Mac gets damaged such that you can’t access important data? That’s when things get expensive, and if you have a 2018 MacBook Pro, you have even fewer options.

Historically, it was relatively easy to remove a drive from a broken Mac and recover the data from it. Data recovery got harder with solid-state storage, and even more so with the introduction of the first MacBook Pro with Touch Bar, thanks to Apple’s new T2 encryption chip, which encrypts data on the drive. To simplify last-ditch data recovery, Apple put a special port on the MacBook Pro’s logic board and provided a custom recovery tool for Apple Authorized Service Providers. With the 2018 MacBook Pro, however, Apple removed that port, so only data recovery specialists like DriveSavers can recover data from such damaged machines, and only then if they have the user’s password.

So please, back up your Mac before something goes wrong. It’s fast, easy, and inexpensive to get started, and we’re happy to help.

iOS Backups

We’ve all seen, if not experienced, a broken iPhone or iPad. They’re durable little devices, but they won’t necessarily survive a drop onto a sidewalk or into a toilet (yeah, it happens). And it’s way too easy to forget your iPhone at the gym or in a restaurant. So a backup is necessary if you don’t want to risk losing precious photos or having to set up a new device from scratch. Plus, just as with a Mac, things can go wrong during major iOS upgrades.

With iOS, though, you don’t need extra software or hardware. Apple provides two ways of backing up your iPhone or iPad, iTunes and iCloud. Neither is necessarily better or worse, and you can—and should!—use both for added safety. We’ve seen situations where an iPhone would refuse to restore its files from iTunes but would from iCloud.

To back up to iCloud, go to Settings > Your Name > iCloud > iCloud Backup, turn the switch on, and tap Back Up Now. For backups to happen automatically in the future, you must have sufficient space in your iCloud account (you get 5 GB for free and can buy more), and your device must be on a Wi-Fi network, connected to power, and have its screen locked.

To back up to iTunes, connect your device to your Mac via a Lightning-to-USB cable, launch iTunes, and click the device icon to the right of the media menu.

Then, in the Backups section, click Back Up Now. If you’re prompted to encrypt your backups, we encourage you to agree since otherwise your backup won’t include passwords, Health information, or HomeKit data. For automatic backups via iTunes, select This Computer. After that, every time you plug into your Mac, it will back up.

If you have sufficient iCloud storage, we recommend backing up automatically to iCloud because its automatic backups work well at night when you’re charging your devices. Then, make extra backups to iTunes whenever you think you might need to restore, such as when you’re getting a new iPhone or iPad, or when you’re about to upgrade to a new version of iOS.

Feeling left behind because you don’t have the latest iPhone or iPad? Don’t, because Apple has a present for you in the form of iOS 12. The new operating system promises to increase performance, particularly for older devices as far back as the iPhone 5s and iPad Air.

But iOS 12 offers more than just a speed boost. Apart from adding fripperies like new animoji, text effects, and camera effects in Messages and FaceTime, iOS 12 helps you use your device less. That’s important, as it becomes increasingly obvious that many people spend more time than they’d like on addictive social media apps, games, and cat videos.

Screen Time

The marquee feature for helping you control device usage is Screen Time. Found in the Settings app, Screen Time reports on how much time you spend using different apps, how often you pick up your device, and how many notifications interrupt you. You can check it anytime and get weekly reports, and use this information to help you reduce undesirable usage.

Screen Time has two helpful options, Downtime and App Limits. With Downtime, you can specify a time period when you can only receive phone calls and use specific apps you set in Always Allowed. App Limits let you set how long you may use certain categories of apps. You can ignore the limit, extending it for 15 minutes or for the rest of the day, but that’s cheating, right?

Even better, you can set Downtime and App Limits for a child’s iPhone or iPad, ensuring that they can’t play games after bedtime or text their friends during dinner.

Notification Management

It’s easy to become overwhelmed with notifications, especially if you have chatty friends in messaging apps. iOS 12 can reduce the impact of non-stop notifications. On the Lock screen, iOS 12 now groups message threads and multiple notifications from the same app. Tapping a group expands it so you can see the details.

Plus, with a feature called Instant Tuning, you can change notification settings for an app right from a notification. Swipe left on a notification and tap Manage. Instant Tuning also lets you send notifications to Notification Center silently so they don’t interrupt you but are available later.

Do Not Disturb

In the “it’s about time” department, iOS 12 beefs up Do Not Disturb so it works more the way people do. When you bring up Control Center and force-touch the Do Not Disturb button, it expands to let you turn on Do Not Disturb for 1 hour, for the rest of the day, or until you leave your current location. The beauty of these new options is that they disable Do Not Disturb automatically so you don’t have to remember—and potentially miss important notifications. Plus, a new Bedtime option in Settings > Do Not Disturb dims the display and silences overnight notifications until you unlock your device in the morning.

Siri Shortcuts

Another new feature, Siri Shortcuts, aims to help you use your device more effectively. As Siri learns your routines, it will start suggesting shortcuts for common actions, either on the Lock screen or when you pull down on the Home screen to search. You can see its suggestions in Settings > Siri & Search > All Shortcuts, and for those that seem useful, record a custom phrase that will invoke the shortcut. Plus, a new Shortcuts app lets you create more complex shortcuts that can run multiple steps at once.

Smaller Changes

Those may be the most significant changes in iOS 12, but they’re far from the only ones. Here’s a sampling of other refinements you’ll notice:

• Apple has redesigned the iBooks app and renamed it Books.
• The News, Stocks, and Voice Memos apps also received redesigns, Stocks and Voice Memos are now available on the iPad, and all three have made the jump to the Mac in Mojave, with their data synced via iCloud.
• A new Measure app uses augmented reality to help you measure objects in the real world.
• In Settings > Battery, iOS 12 shows graphs of battery usage and activity for the last 24 hours or the last 10 days.

iOS 12 has even more minor improvements that we’ll be sharing in the coming months, so watch this space!

Social Media: Apple has loaded iOS 12 with new features, and here’s a rundown of those that will make the most difference in your daily iPhone and iPad experience, including Screen Time, better notifications, improved Do Not Disturb, and more!

It’s that time of year again, when an Apple user’s thoughts drift to new versions of macOS, iOS, watchOS, and tvOS. Apple announced the new versions in June, and public betas have been available since. But once Apple makes macOS 10.14 Mojave, iOS 12, watchOS 5, and tvOS 12 available for free download, you’ll need to decide when to install each.

(Note that we say when and not if. There’s no harm in delaying major operating system upgrades until Apple has had a chance to squash early bugs. But waiting too long puts you at risk from security vulnerabilities and prevents you from taking advantage of new features. Plus, should you have to replace an Apple device unexpectedly, you will likely have to use the current operating system, which could be awkward if you weren’t ready.)

The hardest upgrade decision comes with macOS 10.14 Mojave. Whereas the last version of macOS—High Sierra—was a refinement upgrade that added few new features, Mojave introduces lots. Some people’s eyes will appreciate Dark mode, and the Dynamic Desktop changes subtly throughout the day. More practically, Stacks help organize files on cluttered Desktops, the Finder’s new Gallery view makes browsing images easier, and Quick Actions in the Finder’s Preview pane and in Quick Look let you work on files without even opening them. Apple significantly enhanced macOS’s screenshot and screen recording capabilities as well. And apps like Home, News, Stocks, and Voice Memos make the jump from iOS.

However, these features are bound to come with quirks and bugs, and Mojave’s new privacy and security controls may cause problems for older software. So we recommend waiting until at least version 10.14.2 or even 10.14.4 before upgrading. That gives you time to make sure your key apps are compatible with Mojave and for Apple to resolve any unanticipated problems. Early next year is a good idea to check on updating.

iOS 12 is a different story, particularly if you have an older iPhone or iPad. That’s because Apple has focused on improving performance for such devices. If your device is bogging down, iOS 12 may give it a new lease on life. Also compelling is Screen Time, which helps you track your usage and set limits if you’re unhappy about how much time you spend giving Facebook your personal data. Screen Time even works for your entire family, so it could make dinner less device-intensive. A beefed-up Do Not Disturb lets you keep your iPhone from nagging you so much, and new features let you tamp down excessive notifications more easily. Finally, if you do the same things repeatedly, Siri Shortcuts can help you create your own Siri voice commands.

Our take is that iOS 12 is a good upgrade. Don’t pull the trigger instantly, since Apple may discover important bugs in the first week or two, but after that, upgrade when you have time to play with the new features.

watchOS 5 is linked to iOS 12, so you can’t upgrade your Apple Watch until your iPhone is running the latest. Most of the changes revolve around the Workouts app, with automatic detection of running workouts, a new Yoga workout, activity competitions, and more. Other new features include a Walkie-Talkie app, the arrival of Apple’s Podcasts app, a smarter Siri watch face, and improved notifications. There’s no downside to watchOS 5, so as soon as iOS 12 lands on your iPhone, set your Apple Watch to upgrade that night.

tvOS 12 is the easiest to agree to install. It’s a minor upgrade, with just a few new features. The most noticeable is a new aerial screensaver of Earth from low orbit, made by the crew of the International Space Station. You can also tap the touchpad of the Siri Remote while an aerial screensaver is playing to see where it was taken. When you start trying to type a password on the Apple TV, a notification on your iPhone lets you autofill that password. And finally, the Apple TV 4K gains support for Dolby Atmos soundscapes. So yeah, install tvOS 12 when it comes out, or let your Apple TV do it automatically.

As much as change can be hard, we’re excited about Apple’s new operating systems. Like you, we probably won’t end up using all the new features, but some will enhance the experience of being an Apple user.

There’s an Internet saying: “If you’re not the customer, you’re the product.” The point is that, if you’re getting a service for free, the company providing it sees you not as a customer, but as a product to sell, generally to advertisers.

This is how Google, Facebook, and Twitter operate. They provide services for free, collect data about you, and make money by showing you ads. In theory, the more that advertisers know about you, the better they can target ads to you, and the more likely you’ll be to buy. Personalized advertising can seem creepy (or clueless, when it fails), but it isn’t inherently evil, and we’re not suggesting that you stop using ad-supported services.

This ad-driven approach stands in stark contrast to how Apple does business. Apple makes most of its money by selling hardware—iPhones, Macs, and iPads, primarily. Another big chunk of Apple’s revenue comes from App Store and iTunes Store sales, iCloud subscriptions, and Apple Pay fees. Knowing more about you, what Web pages you visit, what you buy, and who you’re friends with doesn’t help Apple’s business, and on its Privacy page, Apple says bluntly, “We believe privacy is a fundamental human right.”

Of course, once your data is out there, it can be lost or stolen—in June 2018, a security researcher discovered that the online data broker Exactis was exposing a database containing 340 million records of data on hundreds of millions of American adults. Ouch!

Let’s look at a few of the ways that Apple protects your privacy.

Siri and Dictation

The longer you use Siri and Dictation, the better they work, thanks to your devices transmitting data back to Apple for analysis. However, Apple creates a random identifier for your data rather than associating the information with your Apple ID, and if you reset Siri by turning it off and back on, you’ll get a new random identifier. Whenever possible, Apple keeps Siri functionality on your device, so if you search for a photo by location or get suggestions after a search, those results come from local data only.

Touch ID and Face ID

When you register your fingerprints with Touch ID or train Face ID to recognize your face, it’s reasonable to worry about that information being stored where attackers—or some government agency—could access it and use it for nefarious purposes. Apple was concerned about that too, so these systems don’t store images of your fingerprints or face, but instead mathematical signatures based on them. Those signatures are kept only locally, in the Secure Enclave security coprocessor that’s part of the CPU of the iPhone and iPad—and on Touch ID-equipped laptops—in such a way that the images can’t be reverse engineered from the signatures.

And, of course, a major goal of Touch ID and Face ID is to prevent someone from violating your privacy by accessing your device directly.

Health and Fitness

People with medical conditions can be concerned about health information impacting health insurance bills or a potential employer’s hiring decision. To assuage that worry, Apple lets you choose what information ends up in Health app, and once it’s there, encrypts it whenever your iPhone is locked. Plus, any Health data that’s backed up to iCloud is encrypted both in transit and when it’s stored on Apple’s servers.

App Store Guidelines

A linchpin in Apple’s approach to privacy is its control over the App Store. Since developers must submit apps to Apple for approval, Apple can enforce stringent guidelines that specify how apps can ask for access to your data (location, photos, contacts, etc.). This isn’t a blanket protection—for instance, if you allow a social media app <cough>Facebook<cough> to access your contacts and location, the company behind that app will get lots of data on your whereabouts and can even cross-reference that with the locations of everyone in your contact list who also uses the service.

In the end, only you can decide how much information you want to share with the likes of Google, Facebook, and Twitter, and only you can determine if or when their use of your details feels like an invasion of privacy. But by using Apple products and services, you can be certain that the company that could know more about you than any other is actively trying to protect your privacy.

Apple has thrown back the curtain on its latest batch of iPhones and a new model of the Apple Watch. The company also announced plans to release iOS 12, watchOS 5, and tvOS 12 on September 17th. macOS 10.14 Mojave will follow a week later on September 24th.

X Appeal: The New iPhone XS, iPhone XS Max, and iPhone XR

Last year’s iPhone X was a massive hit, so Apple has gone further down that road, dropping the Home button and Touch ID and focusing on Face ID in this year’s iPhones. There are three models: the mid-level iPhone XS (pronounced “Ten Ess”), the big iPhone XS Max, and the less-expensive iPhone XR.

You can pre-order the first two on September 14th, and they’ll ship a week later. Those who want an iPhone XR will have to wait until October 19th to pre-order. Here’s how the pricing shakes out:

• iPhone XS: 64 GB for $999, 256 GB for $1149, 512 GB for $1349
• iPhone XS Max: 64 GB for $1099, 256 GB for $1249, 512 GB for $1499
• iPhone XR: 64 GB for $749, 128 GB for $799, 256 GB for $899

What do you get for your money? All three new iPhones rely on Apple’s new A12 Bionic chip, which promises faster performance and reduced power consumption compared to last year’s A11 Bionic. Along with snappier overall responsiveness, the A12 Bionic enables new computational photography capabilities. Users of these iPhones will enjoy Smart HDR, which combines multiple images behind the scenes to produce better photos, and depth-of-field editing for adjusting the background behind a photo’s primary subject.

Apple also improved the camera hardware, enhancing the dual 12-megapixel rear-facing cameras in the iPhone XS and XS Max with larger, deeper pixels and an improved True Tone flash. The iPhone XR lacks 2x optical zoom because it has only a single rear-facing 12-megapixel camera, but thanks to the A12 Bionic’s processing power, it can still take photos in Portrait mode and do depth-of-field editing. The rear-facing cameras on all three models can capture up to 4K video at 60 frames per second—now with stereo sound. The front-facing camera on each iPhone is a 7-megapixel TrueDepth camera that can also capture 1080p video.

If you carry separate work and personal phones, or if you travel abroad frequently, you’ll appreciate the new dual-SIM capability that lets these iPhones support two phone numbers simultaneously, each with their own plan.

What differentiates these iPhones from one another? One big difference is the screens.

• iPhone XS: 5.8-inch OLED “Super Retina HD” display with a 2436-by-1125 resolution at 458 ppi
• iPhone XS Max: 6.5-inch OLED “Super Retina HD” display with a 2688-by-1242 resolution at 458 ppi
• iPhone XR: 6.1-inch LCD “Liquid Retina” display with a 1792-by-828 resolution at 326 ppi

Apple makes much of the iPhone XR’s LCD display, which is essentially a newer and larger version of the screen in last year’s iPhone 8. It won’t look as good as the OLED screens in the iPhone XS models, but unless you’re watching a lot of video or playing photo-realistic games, you may not notice.

Another difference between these models is size. The iPhone XS is the smallest, clocking in at a few millimeters and grams under the iPhone XR. On the other end of the spectrum, the iPhone XS Max has essentially the same dimensions as the previous iPhone Plus model, with a larger screen.

The other major difference between the iPhone XR and the iPhone XS models is the case material. The iPhone XS models have glass backs and are edged in stainless steel that comes in silver, space gray, and gold. In contrast, the iPhone XR features colorful aluminum casings in red, yellow, white, coral, black, and blue. Both are gorgeous, but if you’re like many people, a protective case will prevent you from appreciating the case material.

Should you consider upgrading to one of these new models? If your existing iPhone is on life support, absolutely. And, if you want the latest and greatest, the iPhone XS models are the best iPhones ever, particularly for photography. But for those with functional iPhones from the past few years, these new models are less compelling, especially since iOS 12 promises to speed up older devices as far back as the iPhone 5s. I myself have the iPhone X, and don’t plan on upgrading this year.

If you decide to buy one, which model you choose probably depends on how much you’re willing to spend since these are Apple’s most expensive iPhones ever. The iPhone XR combines modern technology with a lower price than the other two models, and the decision between the iPhone XS and XS Max comes down to size and cost. Finally, if the prices for the new models are too high, you can still get the iPhone 7 starting at $449 and the iPhone 8 at $599.

Apple Watch Series 4: Bigger Screens and Health Monitoring

In a first for the Apple Watch line, Apple changed the size and shape of the Apple Watch Series 4, boosting the vertical screen dimensions to 40mm and 44mm, up from 38mm and 42mm, and making the screens a little wider to retain the same proportions. However, the new models are 1.1mm thinner and thus have less total volume. You’ll want to try on the different models before buying to see how they look and feel on your wrist. Happily, the Series 4 can use the same bands as previous models.

Apple claims the new display, which extends into the corners of the screen, is “edge-to-edge,” and while there still is a black border, it’s smaller than before. The overall viewing area is about 30% larger.

To use the extra screen space effectively and show off the power of its new S4 chip, the Series 4 comes with some new faces. The Infograph face can incorporate up to eight complications, the Breathe face moves in time with a deep breath, and Vapor, Fire, Water, and Liquid Metal faces animate behind virtual clock hands.

More practically, the Apple Watch Series 4 incorporates new and enhanced sensors. Later this year, the electrodes built into the Digital Crown and the back crystal let you record an electrocardiogram and, after 30 seconds, receive a heart rhythm classification that can identify signs of atrial fibrillation. Recordings are stored securely in the Health app, where you can share them with doctors. Even if you don’t use the ECG app manually, the Series 4 analyzes your heart rhythms in the background and alerts you if it detects irregular rhythms or if the heart rate exceeds or falls below a threshold.

Plus, the Series 4 can now use its accelerometer and gyroscope to detect hard falls. If you fall, the Apple Watch sends you an alert, and if you don’t move for 60 seconds after the notification, it calls emergency services and notifies your emergency contacts of your location.

Other improvements include a speaker that is 50% louder, a relocated microphone to make calls clearer, haptic feedback in the Digital Crown, a back made of sapphire crystal and ceramic for better cellular reception, and Bluetooth 5 for faster data transfer over greater distances.

All this technology comes at a cost, and Apple has raised prices to match. GPS-only models of the Apple Watch Series 4 cost $399, and cellular-capable models are $499 (plus you’ll need to pay an additional $10–$15 for a cell plan). The Apple Watch Series 3 remains available at lower prices: $279 for GPS and $379 for cellular. You can pre-order on September 14th, and the Series 4 will ship on September 21st.

Our take is that the new health-monitoring features of the Apple Watch Series 4 are compelling for anyone who is concerned about falls or heart monitoring. But the increased prices may steer those who are mostly interested in fitness features and iPhone notifications to the cheaper Series 3.

With last year’s macOS 10.13 High Sierra, Apple made no sweeping changes, instead focusing on refinements and bug fixes. In keeping with the company’s alternating cycle of releases, this year’s macOS 10.14 Mojave boasts plenty of new features.

Dark Mode and Dynamic Desktop

In a major visual change, Mojave features a new Dark mode that reverses the standard black-on-white look with light gray text on a dark background throughout the interface—change it in System Preferences > General. If your eyes find white window backgrounds too bright, Dark mode will be a boon. Or, if the current bright approach doesn’t bother you, Dark mode may seem muddy and hard to read because of its reduced contrast.

Dark mode may be useful, but Dynamic Desktop is just eye candy. Select either Mojave or Solar Gradients in System Preferences > Desktop & Screen Saver > Desktop, and your wallpaper will change throughout the day.

Finder Stacks and Groups

Turning to more practical changes, Mojave’s Finder boasts a few new features to help you better navigate a cluttered Desktop and overflowing folders. Control-click the Desktop and choose Use Stacks, and the Finder will combine all the related icons on your Desktop into stacks. It collects them by kind by default, but you can instead have it group them by various dates or even by tags. Click a stack to see what’s inside.

Groups are like Stacks, but within a Finder window. With a Finder window open, choose View > Use Groups, and note that you can use the View > Group By submenu to change the grouping from kind to application, date, size, and tag.

Quick Actions in the Finder and Quick Look

The Finder’s new tricks go even further, with Quick Actions. Controlled in System Preferences > Extensions > Finder, these quick actions let you rotate or mark up a document within the Finder’s preview pane or a Quick Look window (select a file and press the Space bar). Other quick actions let you create PDFs and trim video.

Most useful of these is the Markup quick action, which gives you most of Preview’s editing tools—cropping, annotating, and more—right in a Finder or Quick Look window.

Still and Video Screen Captures, with Editing

Markup also features prominently in Mojave’s new screen capture interface. You’ve long been able to press Command-Shift-3 for a screenshot of the entire screen and Command-Shift-4 for a portion of the screen. Now, press Command-Shift-5 for an interface to those capabilities, plus video screen recording, which was also possible before with QuickTime Player.

These capabilities may not be new, but they’re a lot easier to use in Mojave, and there are a few new options, such as being able to keep the same size selection across multiple screen captures and include the pointer in screenshots.

Continuity Camera with iPhone

Have you ever wanted to insert a photo or scanned page into an email message or document? Mojave makes this easier with Continuity Camera, a feature that lets you use your iPhone within a Mac app. In Mail, for instance, start a new message, and then choose File > Insert from iPhone > Take Photo/Scan Documents. Either way, your iPhone immediately switches to the appropriate photo or scanning mode, and the resulting photo or scan lands in your message.

iOS Apps: News, Stocks, Voice Memos, Home

Apple has been emphatic that it is not planning to retire macOS in favor of iOS. However, the company does want to make it easier for developers to write apps that run in both operating systems. As the first phase of that strategy, Apple has ported four iOS apps to the Mac: News, Stocks, Voice Memos, and Home.

They look a little different from their iOS cousins, as they should, but they work similarly, and you can sync their settings and data between your devices via iCloud (look in System Preferences > iCloud on the Mac and in Settings > Your Name > iCloud in iOS).

There are a variety of other small changes throughout Mojave and in Apple’s standard apps, and we’ll share more of those in future posts, so stay tuned!

The System Preferences app on the Mac contains about 30 icons, each leading to additional settings panes. Rather than opening System Preferences, scanning the collection of icons, and clicking the one you want, you can jump directly to the desired pane. Just click and hold on the System Preferences icon in the Dock, and choose a pane from the pop-up menu.

Photos on the Mac provides so many editing tools that it’s easy to lose track of how an edited image compares to the original. You can always use the Revert to Original command and then undo it, but that’s fussy. Instead, Photos provides a Show Original  button in the upper-left corner, between the window controls and the Revert to Original button. Click and hold it to see your original image; let up to see the edited version again. Even easier, press the M key on your keyboard. The only thing either of those techniques won’t do is show the effect of cropping; to see the uncropped original, press Control-M. And if you just want to see how a particular set of adjustment controls affected the image, click its blue checkmark  to turn it off and back on.

Some Web sites have separate desktop and mobile versions, each theoretically providing the best browsing experience for its platform. Unfortunately, mobile Web sites sometimes leave out necessary features or hide content. That’s especially annoying if you’re browsing on an iPad, where the desktop site would work fine. If you run across such a site while browsing in Safari on the iPhone or iPad, you can ask for its desktop version. Press and hold the Reload button at the right side of the address bar, and then tap Request Desktop Site. If the site allows such a request, as do Wikipedia and the New York Times, the desktop version loads (to read the small text, you may need to pinch out to zoom the page).

On the face of it, Apple’s Find My iPhone feature does what it says. If you lose your iPhone, you can identify its last known location by looking in the Find iPhone app or on the iCloud Web site, and you can make it play a sound. It’s great for tracking down a missing iPhone, whether you misplaced it in the house or left it behind at a restaurant.

But Find My iPhone does much more! For starters, it works with nearly any Apple device. You can use it to locate a missing Mac, iPad, iPod touch, Apple Watch, and even AirPods. Find My iPhone also helps protect your data if a device is stolen. It even works with Family Sharing to locate devices owned by anyone in your family—a boon to any parent with a forgetful teenager.

You must turn on Find My iPhone before your device goes missing!

• In iOS, tap Settings > Your Name > iCloud > Find My iPhone and enable Find My iPhone. (On the iPad, it’s called Find My iPad.) Also on that screen, turn on Send Last Location. Finally, go back to the main level of Settings, tap Privacy > Location Services, and make sure Location Services is turned on.
• On the Mac, open System Preferences > iCloud and select the Find My Mac checkbox—if you see a Details button beside Find My Mac, click it and follow its instructions for setting necessary preferences.

Be sure to practice viewing where your devices are located and playing tones on them so you’ll know what to do if a device goes missing.

Find My iPhone has a few tricks up its sleeve for when you want a device to show a message or if you think it was stolen:

• Lost Mode: When invoking this mode for an iOS device or Apple Watch, you’ll be asked to enter a phone number where you can be reached and a message. After that, Lost Mode will kick in as soon as the device is awake and has an Internet connection. Anyone who tries to use the device will see your message along with a place to enter the device’s passcode. If you get it back, you can enter the passcode to dismiss the message and use it normally.
  
• Lock: Available only for the Mac, the Lock feature enables you to protect an entire Mac with a 4-digit custom passcode. You can also enter a message that will appear on the Lock screen. This is a good choice if you think you’ll get your Mac back but would prefer that nobody mess with it in the meantime. Note that if you lock a Mac, you can’t erase it, as discussed next, so lock it only if you think it can be recovered.
  
• Erase: Even if your device has an excellent passcode or password, you might worry that a thief will access your data. Fortunately, you can erase your device. Erasing a device makes it impossible for you to see its location in Find My iPhone, so it’s a last-ditch effort.
• Activation Lock: If the stolen device is an iOS device or an Apple Watch, when you turn on Find My iPhone, you also enable Activation Lock. This feature prevents someone who has your passcode but doesn’t know your Apple ID and password from turning off Find My iPhone, erasing the device, or setting it up for a new user. In other words, Activation Lock makes it so there’s little reason to steal an iOS device or Apple Watch, since the stolen device can’t ever be used by anyone else. If you get the device back, you can restore your backup—you do have a backup, right?

Find My iPhone works only while the device has power, so if you think you’ve mislaid a device, try locating it right away, before the battery runs out. But even if you are unable to retrieve a lost device, you can prevent others from accessing your data or taking over the device.
