Legitimately Worried That You’re Being Targeted Online? Try Lockdown Mode

Most people fall into one of two extremes when it comes to device security. Many believe they’re not interesting enough to be targeted by online attackers and thus don’t take sensible precautions, like making sure every website account is protected with a strong, unique password. (Most attacks these days are bots, so whether you’re interesting is irrelevant.) Then there are those who see a bogeyman around every corner and refuse to use a password manager or biometric authentication because of misplaced concerns about the security of the stored data. (Really, it’s OK.)

Today we want to focus instead on a very small third group: those who, because of who they are or what they do, have a legitimate reason to fear being targeted by sophisticated digital attacks. Such people might include activists trying to raise awareness about human rights abuses in oppressive regimes, political dissidents, muckraking journalists covering organized crime or government corruption, senior executives in controversial business fields, high-profile government officials, and government employees with access to sensitive information.

For such people, using a password manager and relying on biometric authentication is table stakes. Government intelligence and law enforcement agencies often employ hacking software like Pegasus, which can be installed on target iPhones through zero-click exploits such as simply receiving a malicious text message. Pegasus can read text messages, snoop on calls, collect passwords, track location, access the iPhone’s camera and microphone, and harvest information from apps. Plus, both government agencies and organized crime rings employ hackers to target high-profile targets directly, often through social engineering (pretending to be someone they’re not to gain access to an account or device).

Apple is well aware of the risk to high-value individuals. In November 2021, the company filed a lawsuit against Pegasus maker NSO Group. More practically, Apple introduced Lockdown Mode in iOS 16, iPadOS 16, and macOS 13 Ventura, significantly reducing the attack surface that spyware or hackers could exploit by limiting or blocking specific apps, websites, and features.

Lockdown Mode Limitations

Before we explain how to turn on Lockdown Mode, it’s vital that you understand how it limits your Apple devices:

  • Messages: Most message attachment types are blocked other than certain images, video, and audio. Lockdown Mode also blocks links and link previews.
  • Web browsing: Safari blocks complex Web technologies, potentially causing some websites to load slowly or not operate correctly. It may also block Web fonts and images, so sites may not display as designed.
  • FaceTime: Incoming FaceTime calls are blocked unless you have previously called that person.
  • Apple services: Invitations to Apple services, such as invitations to join the Home app, are blocked unless you have previously invited that person.
  • Shared albums: Shared albums disappear entirely from the Photos app, and shared album invitations are blocked.
  • Device connections: If you want to connect an iPhone or iPad to a computer or accessory, the device must first be unlocked. Similarly, connecting an M-series Mac laptop to an accessory requires explicit approval.
  • Configuration profiles: Lockdown Mode prevents you from installing configuration profiles, and the device can’t be enrolled in Mobile Device Management.

The inconvenience these restrictions create is well worth the protection Lockdown Mode provides if you’re a sufficiently high-value target. But for the vast majority of Apple users, Lockdown Mode’s limitations would just cause confusion and annoyance.

Turning on Lockdown Mode

First, note that you must enable Lockdown Mode on each of your devices separately.

To enable Lockdown Mode on an iPhone or iPad, go to Settings > Privacy & Security > Lockdown Mode (at the bottom) and tap Turn On Lockdown Mode on two separate screens. For the last step, tap Turn On & Restart, and enter your passcode.

Once your iPhone restarts, it will work mostly the way you expect, apart from the above limitations. You may see notifications when an app has been limited in some way, and a banner appears in Safari to let you know you’re in Lockdown Mode.

On a Mac, turn on Lockdown Mode by going to System Settings > Privacy & Security. Scroll down to Lockdown Mode and click Turn On. Authenticate, then click Turn On & Restart.

As with the iPhone and iPad, Lockdown Mode mainly makes its presence known by displaying a banner in Safari; you may also receive notifications when an app or feature is limited.

Allow Certain Apps or Websites in Lockdown Mode

If you discover that a particular app or website isn’t operating correctly in Lockdown Mode, you can exclude it from Lockdown Mode’s protections. You’ll have to decide if it’s worth the added risk. To manage exceptions on the iPhone or iPad, go to Settings > Privacy & Security > Lockdown Mode. Then scroll to the bottom, tap Configure Web Browsing, and on the next screen, turn off the switch for the desired app.

To exclude websites from Lockdown Mode, use Safari. Tap the AA button in the address bar, disable the Lockdown Mode switch, and tap Turn Off. The Lockdown banner changes to Lockdown Off to make sure you know that website is no longer being limited for your protection.

On the Mac, you can exclude websites in Safari, but not apps. While on the site you want to exclude, choose Safari > Settings for website.name. In the popover that appears, deselect Enable Lockdown Mode and then click Turn Off when prompted.

To reiterate, almost no one needs to enable Lockdown Mode. But if you qualify as a high-value target, it’s well worth using Lockdown Mode to reduce the chances that powerful forces will be able to compromise your iPhone, iPad, or Mac.

Keep Your Apple Devices Cool in the Summer Heat

June 2023 was the hottest month on record for the planet, at least until July 2023. Among the many ill effects of such heat are what it does to iPhones, iPads, Macs, Apple Watches, and other digital devices. Excessive heat shortens the overall lifespan of lithium-ion batteries and increases the likelihood of both transient errors and hardware failures—iPhones warn you when they’re getting too hot because of these issues. Apple recommends using nearly all its devices in conditions no hotter than 95ºF/35ºC and storing them in locations that don’t exceed 113ºF/45ºC. (The exception is the adventurous Apple Watch Ultra, which can be worn in temperatures up to 130ºF/55ºC.) The most common place to avoid is a car parked in the sunshine on a hot day, which can easily exceed 130ºF within an hour and rise from there. So don’t leave your iPhone in the car during an afternoon at the beach!

AirNow and Paku: Two Helpful Apps for Monitoring Air Quality

Smoke from wildfires is causing significant air quality problems for much of Canada and the US. It’s important to check the Air Quality Index (AQI) before spending a long time outside, and that’s especially true for sensitive populations (children, the elderly, anyone with asthma or other breathing issues) and for those exercising outdoors. Although numerous weather apps report air quality, their data can vary widely. Instead, turn to the official AirNow app published by the US Environmental Protection Agency. It provides the canonical AQI readings, and its Fire & Smoke Map lets you see where the smoke is and how that relates to air quality. (The AirNow website provides the same tools on a Mac, plus a lot of helpful background information.) For hyperlocal readings, check the PurpleAir network of inexpensive air monitors. PurpleAir’s website works in Safari on the iPhone, but the Paku app also provides iPhone widgets and Apple Watch complications showing the AQI from nearby monitors.

Learn to Identify and Eliminate Phishing Notifications

Email may be the most common form of phishing, but it’s not the only one. Modern Web browsers support a technology that enables websites to display system-level notifications just like regular apps. These push notifications have good uses, such as letting frequently updated websites inform users of new headlines, changed discussion threads, and more.

Unfortunately, push notifications can be subverted for malicious purposes, notably phishing. Here’s what happens. You visit a website that asks you if you’d like to receive notifications.

That request may be introduced with language that implies you must agree in order to get desired content, or it may be a bald-faced request to show notifications. If you agree, the website will be able to display alarming or deceptive phishing notifications even when it’s not open.

The goal is to trick you into clicking the notification, which will load a fake site that attempts to get you to enter login credentials or credit card information to facilitate identity theft.

The danger of phishing notifications is that they come from the system, so they may seem more legitimate than email messages trying to sucker you into revealing personal information. Nevertheless, as you can see in the examples above, they may still look sketchy in ways reminiscent of phishing emails:

  • No legitimate website would use emoji or symbols in a notification, much less multiple ones.
  • Although there are no glaring spelling or grammar mistakes, the use of all caps in the top notification is a giveaway. Similarly, standard notifications wouldn’t use exclamation points.
  • The use of “Click here” is poor information design that’s unlikely to come from a professional programmer or Web designer.

Phishing notifications, although problematic, aren’t a malware infection, and anti-malware packages won’t detect or remove them. Luckily, they’re easy to control and block in Safari and other Web browsers.

Prevent Phishing Notifications

The easy way to ensure you don’t see phishing notifications is to allow only trusted websites to send notifications. In general, we recommend keeping that list small so you’re not frequently interrupted by unnecessary notifications.

If you’re unsure that you’ll be able to identify malicious websites, you can enable a browser setting that prohibits all websites from asking for permission to send notifications. In Safari, choose Safari > Settings > Websites > Notifications, and deselect “Allow websites to ask for permission to send notifications” at the bottom.

Other browsers have similar options, and most will look like Google Chrome, as shown below:

  • Arc: Choose Arc > Settings > General > Notifications and select “Don’t allow sites to send notifications.”
  • Brave: Navigate to Brave > Settings > Privacy and Security > Site and Shield Settings > Notifications and select “Don’t allow sites to send notifications.”
  • Firefox: Go to Firefox > Settings > Privacy & Security > Notifications and select “Block new requests asking to allow notifications.”
  • Google Chrome: Navigate to Chrome > Settings > Privacy and Security > Site Settings > Notifications and select “Don’t allow sites to send notifications.”
  • Microsoft Edge: Choose Microsoft Edge > Settings > Cookies and Site Permissions > Notifications and turn off “Ask before sending.”

Browsers based on Chrome (everything except Firefox in the list above) offer a “Use quieter messaging” option that replaces the permission dialog with a bell icon next to the site name in the address bar—click it to allow notifications from that site.

Eliminating Phishing Notifications

Now you know how to prevent new sites from requesting permission to display notifications. What about sites that already have permission? It’s easy to block them in Safari’s Notifications settings screen. If you have any undesirable sites with Allow in the pop-up menu to the right of their name in the Notifications screen, choose Deny from that menu. You could remove the site instead, but that would allow it to ask for permission again.

Firefox’s interface is similar to Safari’s, but Chrome-based browsers have a different interface that separates the blocked and allowed sites. To block a website whose notifications you no longer want to receive, click the button to the right and choose Block. Again, you could remove undesirable sites if you prefer, but remember that if your notification settings ever change, doing so could allow the site to ask for permission once more.

Ultimately, it’s easy to avoid phishing notifications by paying attention as you browse the Web. Steer clear of websites that make an unexpected request to display notifications. Notifications aren’t necessary on hardly any websites, so there’s no harm in denying such requests unless you’re sure they’re legitimate.

Adjust AirPods Options in the Settings App

If you sometimes have trouble configuring your AirPods, here’s the trick. The AirPods settings screen is available only when the AirPods are connected to your iPhone, so you must open their case or put them in your ears. Once you do that, a new item with the name of the AirPods appears at the top of the Settings app. Tap it to switch between Noise Cancellation and Transparency, configure what the press-and-hold action does, and start ear tip tests.

Improve Privacy by Removing Metadata from Office Documents and PDFs

When we share data with others, we do so intentionally—a law firm sending a client legal documents, for instance. But those documents shouldn’t include ancillary information that might reveal other, more sensitive details. Because all digital files contain metadata—additional information about the file or its contents—it’s worth knowing what you could share inadvertently and learning how to avoid doing so.

Much metadata is innocuous, like file type and file size. However, some common file types contain additional metadata that can reveal information that you might not want to share. In this situation, the most common file types are Microsoft Office documents and PDF files. Let’s look at each and how you can see what metadata is there and remove it before sharing.

Cleaning Metadata from Microsoft Office Documents

Metadata that you might want to remove from Microsoft Office documents falls into two broad categories: reviewer information, like comments and tracked changes, and document properties.

The first thing to do when removing metadata is to use File > Save As to make a copy of your file and work on the copy. This automatically removes or resets some metadata and allows you to delete other metadata without worrying about losing it from your original.

If you use change tracking in Word or comments in any Office app, you may want to remove those before sharing a document to prevent recipients from seeing internal conversations or information about who worked on the document.

To remove change tracking and comments in Word, click Review in the toolbar. Next, click the arrow next to the Delete button in the comments section and choose Delete All Comments in Document. Finally, click the arrow next to Accept in the change tracking section and choose Accept All Changes and Stop Tracking. Browse through the document to make sure accepting all changes didn’t do something unexpected, and then save.

Excel and PowerPoint lack change tracking but let you add comments. Like Word, PowerPoint’s Review toolbar offers a similar menu associated with the Delete button; choose Delete All Comments in Presentation to clear the comments. In Excel, switch to the Review toolbar, choose Edit > Select All (comments can be deleted only from selected cells), and click the Delete button in the toolbar.

To see what metadata is in the document properties of a Word, Excel, or PowerPoint document, choose File > Properties, and look in the Summary, Statistics, and Custom tabs. Generally speaking, these won’t contain anything damning, but they may reveal information like the names of people associated with the document. Don’t assume there’s no metadata here just because you didn’t add anything manually—document control systems can add metadata you don’t expect.

The three Office apps offer different approaches to removing personal information in the Summary and Custom tabs, and the process is extremely different than in the Windows versions. (For Windows, refer to Microsoft’s instructions.) Here’s how you remove personal information:

  • Word: Choose Tools > Protect Document, and in the Password Protect dialog, select “Remove personal information from this file on save.” Save the document, and then go back to File > Properties to make sure it removed everything that concerns you.
  • Excel: Choose Excel > Preferences > Security, and select the “Remove personal information from this file on save” checkbox. Then save the document and verify that the desired metadata is gone.
  • PowerPoint: PowerPoint appears to lack that checkbox, but you can choose File > Properties and manually delete all the information from the Summary and Custom tabs before saving the document.

Information in the Statistics tab is generally cleared or reset by using File > Save As, so you don’t need to do anything more to clear it.

If you’re truly concerned about not revealing additional information in shared Office documents, think about what might appear in headers and footers, footnotes, text that’s white (and thus invisible), hyperlinks, and macros. Finally, remember that you can hide text in Word, columns and rows in Excel, and slides in PowerPoint—that hidden content may reveal sensitive information if it’s allowed to remain in a shared document. In PowerPoint, you may also want to check for presenter notes you don’t want to share; choose View > Notes.

Cleaning Metadata from PDFs

Another way to remove a great deal of metadata from Office documents is to share a PDF of the document instead. By “printing” to PDF, anything that’s invisible automatically disappears. However, PDFs have their own metadata that you might want to review and remove. How you go about it depends on which apps you have available: Adobe Acrobat Pro or just Apple’s bundled Preview.

First, to view metadata in Acrobat Pro, choose File > Properties and click the Description tab (left). In Preview, choose Tools > Show Inspector and click the leftmost General Info tab (right).

Adobe Acrobat Pro provides several tools for redacting content (replacing it with a black box) and removing hidden content and metadata. To access them, click the Tools tab at the top of the screen and click Redact to display a pair of buttons on the secondary toolbar. Redact Text & Images lets you redact content, but you’ll most likely want to use Sanitize Document, which removes metadata and a boatload of possible hidden data.

It’s easiest to click Remove All, but you might prefer to click Selectively Remove and look at what Acrobat Pro finds before clicking the Remove button in the Hidden Information tab.

For those who rely on Preview for working with PDFs, there’s a simple process for removing metadata and anything else lurking in a PDF that’s good enough for most situations.

Choose File > Print, and then choose Save As PDF from the pop-up PDF menu at the bottom of the Print dialog. This may seem counterintuitive, but as with any other document type, printing in this way creates a PDF that contains only the visible information in the original, ensuring that all hidden data and metadata are removed.

Although all Mac users have Preview, there is another common option for removing metadata from PDFs—online tools. They’re easily found, but we urge caution. If you’re concerned about the recipient of your PDF being able to see metadata or hidden content, why would you trust a free online service with that information? If you want to head down this path, stick with sites headquartered in the European Union, which has stronger privacy regulations than other parts of the world. For instance, Metadata2Go, which displays all the metadata in a file, is in Germany, and Sejda, whose Edit PDF Metadata tool can remove all metadata, is based in the Netherlands.

One last thought. If you’ve gotten to this point and are thinking that you need an enterprise-wide solution to removing metadata, look for services like Adarsus’s MetaClean, which can automatically remove metadata from files sent as email attachments or stored on file servers.

Choosing the Best Mac for a College-Bound Student in 2023

Do you have a child starting college soon? It’s likely that your kid has been relying heavily on a computer throughout high school, but if it was a school-provided laptop or shared family computer, now’s the time to get them something of their own. Even if they had their own laptop throughout high school, if it’s old or unreliable, college is a good excuse to bring them up to date. If you haven’t been paying close attention to Apple’s Mac lineup, you might wonder which model makes the most sense.

First, don’t buy anything without first checking with the college. Many college departments have specific requirements based on the software students use in their classes. Generally, these revolve around processor type, amount of RAM, and storage space. Current Macs should meet or exceed all those requirements. Second, see if the college provides access to education pricing—most will—to save a few hundred dollars off the prices listed below. Regardless, Apple often has a Back to School offer.

Colleges often specify—and students usually prefer—laptops instead of desktop machines. Although the M1 24-inch iMac is an excellent machine with a gorgeous screen, it’s too big and unwieldy for the nomadic lifestyle of the typical college student. The same applies to an M2 Mac mini or Mac Studio with an external display. Students can take a laptop to class daily, and bringing it home on breaks is a lot easier. A student accustomed to taking notes on an iPad with a keyboard and Apple Pencil might be able to use that along with a desktop Mac, but most students should focus on laptops.

In the past, deciding which model was best for a given student was more challenging, but Apple’s move to the speedy and power-efficient M1 and M2 chips makes the decision easier. We see three primary scenarios:

  • Most students: Buy Apple’s MacBook Air. It’s Apple’s lightest and least expensive laptop. Within the MacBook Air line, you have three choices. The least expensive is the 13-inch M1 MacBook Air from 2020, which starts at $999, but the 13-inch M2 MacBook Air is a better choice for most people, thanks to its bigger-brighter-better 13.6-inch screen, faster performance, 24 GB memory ceiling, and higher-resolution webcam. It now starts at $1099. Those who want a larger screen should look at the just-released 15-inch M2 MacBook Air, which starts at $1299. Apart from the 15.3-inch screen, the only difference from the 13-inch model is a six-speaker system, up from four speakers.
  • Better specs: If performance is more important than cost—especially if your student will be working with processor-intensive tasks like video editing—look to the 14-inch MacBook Pro. It features a powerful M2 Pro chip or an even faster M2 Max chip, and it can be configured with more memory. Although its 14.2-inch screen is physically a little smaller than that of the 15-inch MacBook Air, it has a somewhat higher resolution. Its price starts at $1999.
  • Windows compatibility: The only downside of the transition to Apple silicon is that it’s somewhat more difficult to run Windows using virtualization software like Parallels Desktop (half-price for students and officially supported by Microsoft) or VMware Fusion (free for students but much harder to set up and not officially supported by Microsoft). If Windows compatibility is a bonus but not essential, Parallels Desktop and Windows 11 on Arm should work. However, if Windows compatibility is paramount, your choices are a used Intel-based MacBook Pro or—much as we hate to say it—a PC laptop that runs Windows natively.

Regardless of which laptop you decide on, you’ll have to pick a processor, amount of memory, and storage capacity:

  • Processor: With the 13-inch M1 MacBook Air, you’re limited to the M1 chip with an 8-core CPU and 7-core GPU. With the 13-inch M2 MacBook Air, the M2 chip always has an 8-core CPU, but you can pay $100 to upgrade from an 8-core GPU to a 10-core GPU. The 15-inch M2 MacBook Air always comes with a 10-core GPU. The performance difference isn’t likely noticeable with everyday apps, but for $100, it might be worth upgrading, just in case. The 14-inch MacBook Pro has two M2 Pro options and two more M2 Max options, and choosing between them is probably best done by weighing likely performance needs against the (significantly) increased cost.
  • Memory: The 13-inch M1 MacBook Air offers the choice of 8 GB or 16 GB. 8 GB is acceptable for most college students, but we’d encourage 16 GB to reduce the chance that memory becomes a limiting factor in performance. The M2 MacBook Air lets you choose from 8 GB, 16 GB, or 24 GB, and again, we’d default to 16 GB unless there’s some particularly memory-hungry software in play. With the 14-inch MacBook Pro, the amount of memory goes with the chip. The M2 Pro comes with 16 GB standard, but you can opt for 32 GB. With the M2 Max, 32 GB is standard, with options to upgrade to 64 GB or 96 GB.
  • Storage: For all the MacBook Air models, 256 GB is the lowest storage level, and you can upgrade to 2 TB. The 14-inch MacBook Pro starts at 512 GB and offers upgrades up to a whopping 8 TB. Choose the amount of storage based on two considerations: budget (it gets expensive fast) and anticipated usage (audio and especially video can consume a lot of space, as can large numbers of photos, but most other uses don’t). Remember that it’s easy to connect an external Thunderbolt SSD or hard drive to offload large files that don’t have to be kept available at all times. Large files can also be kept in cloud-based storage.

To our thinking, the most obvious choice for a Mac that’s likely to last for four years of college would be either the 13-inch or 15-inch M2 MacBook Air with a 10-core GPU, 16 GB of memory, and 512 GB of storage. Be sure to budget for AppleCare+, too; it’s almost guaranteed that some mishap will befall a student laptop, and AppleCare+ covers up to two incidents of accidental damage every year.

You’ll need to have some conversations with your child to find out what they think they’ll need—and be sure to double-check that against the college’s recommendations—but if you have any questions after that, don’t hesitate to contact us.

Convert Image Formats Directly in the Finder

If you need to convert images to JPEG, PNG, or (unlikely) HEIF, try this hidden Finder feature: Control-click an image in one of those formats or other common image formats like TIFF, GIF, or PSD, and choose Quick Actions > Convert Image. A dialog lets you choose the destination format, the image size, and whether you want to preserve metadata. For straight conversions, stick with Actual Size, but if your goal is to shrink the file as well, you can choose a smaller image size. Leave Preserve Metadata selected unless you want to remove things like location metadata for privacy reasons. You can even select multiple files to convert them all at once.

The Hardware You’ll Need to Run Apple’s 2023 Operating Systems

At Apple’s Worldwide Developer Conference in June, the company unveiled the upcoming versions of its operating systems: macOS 14 Sonoma, iOS 17, iPadOS 17, watchOS 10, and tvOS 17. They won’t be available until September or October of 2023, and even once they ship, we recommend waiting a few weeks before upgrading your smaller Apple devices and holding off on macOS upgrades for a couple of months.

Regardless, it’s worth considering how these operating systems might impact your plans to buy new hardware in the next six months. Any Apple device you purchase now—or have bought in the last five years—can run the new operating systems. But some devices that can run the current macOS 13 Ventura, iOS 16, and iPadOS 16 won’t be upgradable to their replacements later this year. More importantly, some older devices that can be upgraded won’t support all the new features.

Here’s what you’ll need and compatibility gotchas to keep in mind.

macOS 14 Sonoma

For macOS 14 Sonoma, Apple has dropped support for Mac models released before 2018. That works out to five models across the iMac, MacBook Pro, and MacBook product lines. If you rely on one of those Macs and want to run Sonoma, think about when it would make sense to buy a new Mac, perhaps in early 2024. By then, all new Macs will likely ship with Sonoma. These Macs can run Sonoma:

  • iMac: 2018 and later
  • iMac Pro: 2017
  • MacBook: None
  • MacBook Air: 2018 and later
  • MacBook Pro: 2018 and later
  • Mac mini: 2018 and later
  • Mac Pro: 2019 and later
  • Mac Studio: 2022 and later

The specific 2017 Mac models that are stuck at Ventura are:

  • iMac: 21.5-inch and 27-inch
  • MacBook Pro: 13-inch and 15-inch
  • MacBook: 12-inch

Unsurprisingly, some new features in Sonoma require sufficient processing power that they work only on Macs with Apple silicon—one of the M1 or M2 chips.

  • Game Mode: This special mode automatically gives games top priority on the CPU and GPU, lowering usage for background tasks. It also reduces latency for wireless accessories, like game controllers and AirPods, for improved responsiveness.
  • Just “Siri”: Although dropping “Hey” from the “Hey Siri” trigger phrase works on all iPhones with iOS 17 and iPads with iPadOS 17, it requires a Mac with Apple silicon or when using the AirPods Pro (2nd generation).
  • Made for iPhone hearing aids: Apple-compatible hearing aids can now be paired directly with Macs, but only those with an M1 Pro, M1 Max, M1 Ultra, or M2. That works out to the MacBook Pro (14-inch, 2021), MacBook Pro (16-inch, 2021), Mac Studio (2022), and all Macs with the M2.
  • Presenter Overlay: You can keep your image visible while sharing your screen on a video call, either in front of the shared screen or in a small movable bubble.
  • React with your hands: During video calls, 3D augmented-reality reaction effects like hearts, confetti, and fireworks can be triggered with hand gestures, but only on Macs with Apple silicon or when using Continuity Camera with an iPhone 12 or later.
  • Screen Sharing performance improvements: Apple has radically improved the performance of the Screen Sharing app over high-bandwidth connections, but it requires the advanced media engine in Apple silicon.

If you’re unsure which Mac you have, choose About This Mac from the Apple menu.

iOS 17

With iOS 17, Apple has maintained the same cutoff date as Sonoma, supporting all iPhone models released in 2018 and later. That means you’ll be able to run iOS 17 on these iPhones:

  • iPhone 14/Plus/Pro/Pro Max
  • iPhone 13/mini/Pro/Pro Max
  • iPhone 12/mini/Pro/Pro Max
  • iPhone 11/Pro/Pro Max
  • iPhone SE (2nd generation or later)
  • iPhone XR/XS/XS Max

Practically speaking, these iOS 16-compatible devices won’t be able to upgrade to iOS 17:

  • iPhone X
  • iPhone 8/8 Plus

Several new iOS 17 features have more restrictive system requirements.

  • Enhanced autocorrect: iOS 17 enhances autocorrect so it works better (and yes, it will let you use curse words), and it temporarily underlines autocorrected words so you can see which ones were changed. It requires an iPhone 12 or later.
  • Inline predictions: Similarly, inline predictions of what you’re going to type—so you can just accept the suggestion rather than tapping out all those letters—require an iPhone 12 or later.
  • Point and Speak: Those with vision disabilities might appreciate the Point and Speak feature that makes it easier to interact with physical objects that have text labels, but it works only on the Pro models of the iPhone 12, iPhone 13, and iPhone 14.
  • React with your hands: The hand-triggered video call reactions require an iPhone 12 or later.

If you can’t remember which iPhone model you have, go to Settings > General > About and look next to Model Name. This works for the iPad, too.

iPadOS 17

It’s more involved to determine whether your iPad can upgrade to iPadOS 17 because there are four different iPad model types with varying capabilities. These models can run iPadOS 17:

  • iPad Pro 12.9-inch (2nd–6th generation)
  • iPad Pro 11-inch (1st–3rd generation)
  • iPad Pro 10.5-inch
  • iPad Air (3rd–5th generation)
  • iPad (6th–10th generation)
  • iPad mini (5th & 6th generation)

While that list encompasses a lot of iPads, a simpler way to look at it is that only three iPad models that can run iOS 16 won’t be able to upgrade to iOS 17:

  • iPad Pro 12.9-inch (1st generation)
  • iPad Pro 9.7-inch
  • iPad (5th generation)

Because Apple extended overall iPadOS 17 compatibility somewhat further back than it did with iOS 17 and macOS Sonoma, quite a few iPadOS 17 features work only on select models:

  • Back-to-back Siri requests: Although all iPhones will let you issue multiple requests to Siri without reactivating it, on the iPad, the feature works only on an iPad Pro 12.9-inch (3rd generation and later), iPad Pro 11-inch (1st generation and later), iPad Air (3rd generation and later), iPad mini (5th generation and later), or iPad (8th generation and later).
  • Enhanced autocorrect: This improvement to typing requires an iPad Pro 12.9-inch (5th generation and later), iPad Pro 11-inch (3rd generation and later), iPad (10th generation), iPad Air (4th generation and later), or iPad mini (6th generation).
  • External display cameras: If you want to take advantage of an external display’s camera while it’s attached to the iPad, you’ll need an iPad Pro 12.9-inch (3rd generation and later), iPad Pro 11-inch (1st generation and later), iPad (10th generation), iPad Air (4th generation and later), or iPad mini (6th generation).
  • FaceTime with Apple TV: Using an iPad’s mic and camera for FaceTime on an Apple TV 4K (2nd generation) requires an iPad Pro 12.9-inch (3rd generation and later), iPad Pro 11-inch (1st generation and later), iPad (8th generation and later), iPad Air (3rd generation and later), or iPad mini (5th generation and later).
  • Inline predictions: Getting suggestions about what to type next on the iPad requires an iPad Pro 12.9-inch (5th generation and later), iPad Pro 11-inch (3rd generation and later), iPad (10th generation), iPad Air (4th generation and later), or iPad mini (6th generation).
  • PDF AutoFill: iPadOS 17 will use machine learning to analyze PDFs, and if it detects a form, you can fill it out automatically using your contact information. But only if you’re using an iPad Pro 12.9-inch (3rd generation and later), iPad Pro 11-inch (1st generation and later), iPad Air (3rd generation and later), iPad mini (5th generation and later), or iPad (8th generation and later).
  • React with your hands: As with the iPhone and Mac, only some models let you trigger reactions with gestures: the iPad Pro 12.9-inch (5th generation and later), iPad Pro 11-inch (3rd generation and later), iPad (10th generation), iPad Air (4th generation and later), and iPad mini (6th generation).
  • Screen Distance: This health-related feature is supposed to encourage kids to hold the iPad farther away to reduce the likelihood of developing myopia. But how many kids read on an iPad Pro 12.9-inch (3rd generation and later) or iPad Pro 11-inch (3rd generation and later)?

watchOS 10

The Apple Watch has a simple upgrade story: every model compatible with watchOS 9 can also run watchOS 10. That means everything from the Apple Watch Series 4 up through the Apple Watch Ultra, including the Apple Watch SE. (Look in the Watch app on your iPhone if you can’t remember which model you have.)

Two of the new features promised for watchOS 10 work only on specific models:

  • The NameDrop feature that lets you transfer contact information wirelessly with just proximity works with all iOS 17-compatible iPhones, but it can communicate only with an Apple Watch SE, Apple Watch Series 6 or later, or Apple Watch Ultra.
  • The Time in Daylight feature that helps parents track whether their kids are spending the recommended 80–120 minutes per day outside requires an Apple Watch SE (2nd generation), Apple Watch Series 6 or later, or Apple Watch Ultra.

tvOS 17

As with the Apple Watch, the Apple TV upgrade situation is easy to understand: tvOS 17 will run on the Apple TV HD and Apple TV 4K (1st and 2nd generation), just as with tvOS 16.

However, note that the promised option to let you use the mic and camera from an iPhone or iPad for FaceTime calls on the Apple TV works only if you have an Apple TV 4K (2nd generation). That might be the first real reason to upgrade from an older Apple TV.

Consider Moving Your Mac’s Dock to the Side of the Screen

For most of us, our Mac’s screen is wider than it is tall, so longer Web pages and documents often benefit from more room from top to bottom. To maximize the amount of usable vertical space and reduce the need to scroll as much, you can set the Dock to hide automatically and appear only when you move your pointer to the bottom of the screen. A better approach is to position your Dock on the side of your screen where it’s less likely to use space you’d prefer to have available for content. Many people prefer the right side, but you can also try the left to see how it works for you. The easy way to move the Dock is to Control-click its separator bar and choose the desired side from the Position on Screen menu.
