With mask wearing over the past year rendering Face ID ineffective at cash registers, we’ve become fond of using the Apple Watch for contactless payments with Apple Pay. We recommend it highly since it’s so fast and convenient. Once you’ve set up a credit card in the Wallet app on your iPhone, switch to the Watch app, go to My Watch > Wallet & Apple Pay, and tap the Add button next to the desired card. From then on, to pay for a purchase, double-click the Apple Watch’s side button and put it very close to the reader. (We generally turn our arms so we can put the Apple Watch face flat on the reader.) It takes just seconds and tends to wow cashiers who haven’t seen it before.

As climate change continues to wreak havoc on our weather, many areas are seeing record temperatures this summer—all of us in the Pacific Northwest know about that! You may be able to trade your business suit for shorts or skirts to stay more comfortable, but your electronic gear can’t do the same. Keeping your tech cool is about more than comfort—as temperatures rise, performance can suffer, charging may get slower or stop, various components might be disabled, and devices can become unreliable.

How Hot Is Too Hot?

You might be surprised by how low the recommended operating temperatures for Apple devices are—whether you’re talking about an iPhone 12 or an M1-based MacBook Pro, the company recommends keeping them under 95° F (35° C).

Such temperatures happen regularly throughout the summer. Even in cooler climes, the temperature in a parked car in the sunshine can easily hit 130º F (54º C) in an hour and rise higher as time passes. And no, opening the windows a few inches won’t make much difference. You know you shouldn’t leave a kid or dog in a parked car for that reason, and now you can see that leaving your iPhone in the car during an afternoon at the beach might be problematic as well. Apple says its products shouldn’t even be stored—turned off—at temperatures over 113º F (45º C).

It’s not just cars you have to think about. Temperatures in homes and offices without air conditioning can also rise higher than electronics would prefer, and that’s especially true for computers that stay on most of the time and aren’t located in well-ventilated areas.

What’s the Danger?

First off, remember that all electronic devices produce their own heat on top of the ambient heat in the environment, so the temperature inside a device can be much, much hotter than outside. The CPU in an iMac can hit 212º F (100º C) under heavy loads.

Temperatures that exceed component design specs can have the following detrimental effects:

• Chips of all types can behave unpredictably as increased thermal noise (electrons vibrating more) causes a higher bit error rate. Because electrical resistance increases with heat, timing errors can also occur.
• Lithium-ion batteries discharge well in high temperatures, but the increased rate of chemical reactions within the battery will result in a shorter overall lifespan.
• As devices heat and cool, the uneven thermal expansion of different materials can cause microscopic cracks that can lead to a variety of failures over time.

Some heat-related problems are temporary, so when the device or component cools down, it will resume working correctly. But others are irreversible and worth avoiding.

When a Mac gets too hot, it will spin up its fans in an attempt to keep its internal components cool. (The M1-based MacBook Air doesn’t have a fan, so it won’t be able to provide the same level of advance warning.) If your Mac’s fans ever run at full tilt for more than a few minutes, first quit apps you aren’t using, particularly those that might be CPU-intensive, thus creating a lot of heat. If that doesn’t make a difference, restart it to ensure the problem isn’t some rogue process. If the fans come back on at full speed quickly, shut it down and let it cool off for a bit. In the worst case, an overheated Mac may start acting unpredictably or crash.

iOS devices don’t have fans, so they employ other coping mechanisms. If your iPhone or iPad gets too hot, the device will alert you.

Apple says you might notice some of the following behaviors with an overheating iPhone or iPad:

• Charging, including wireless charging, slows or stops.
• The display dims or goes black.
• Cellular radios enter a low-power state. The signal might weaken during this time.
• The camera flash is temporarily disabled.
• Performance slows with graphics-intensive apps or features.

If you’re using Maps on an overheating iPhone for GPS navigation in the car, it may show a “Temperature: iPhone needs to cool down.” screen instead of the map. You’ll still get audible turn-by-turn directions, and the screen will wake up to guide you through turns,

How to Keep Your Tech Cool

For the most part, keeping Apple devices cool just requires common sense:

• Avoid using devices when the temperature is over 95º F (35º C). If that’s impossible, keep usage to a minimum.
• Don’t leave devices in cars parked in the sun for long periods of time. If it happens accidentally, let the device cool before using it.
• Provide good ventilation so air can cool the device. Don’t block ventilation ports in the back of desktop Macs, and don’t use Mac laptops in bed, propped on a pillow, or under the covers. It can be worth blowing dust out of ventilation ports with compressed air every so often.
• Never put anything on the keyboard of an open Mac laptop.
• Avoid stacking things on top of a Mac mini.
• Monitor the temperature of server closets. If they get too hot, keep the door open, add a fan, or run the air conditioning.

Luckily, the temperatures that cause problems for Apple hardware aren’t terribly comfortable for people either, so if you’re way too hot, that’s a good sign your gear is as well.

It’s tempting to think that most external storage devices—whether simple hard drives or more complicated network-attached storage (NAS) units—are relatively similar because they all do roughly the same thing. However, a recent problem with older Western Digital My Book Live NAS devices highlighted that there can be large differences. In that case, hackers figured out how to cause a factory reset that wiped the entire drive of all files. (If you have one, note that Western Digital recommends disconnecting it from the Internet immediately.) Two tips: Although no one could have anticipated this particular problem, ask us before buying external storage because we may be able to recommend known good products or warn you away from sketchy manufacturers. Also, if you store unique data on an external drive, you must back up that drive just like your Mac’s internal drive or risk losing everything, like these My Book Live owners did. Backup, backup, backup!

For many people, increasing vaccination rates mean that long-delayed vacations are now possible, and in-person conferences are slowly starting up again too. But before you head out for the beach or the convention center, you’ll want to write an out-of-office email auto-reply message to send to everyone who tries to get in touch while you’re away. A bit of thought upfront could reduce stress for your correspondents—and ensure that they don’t hunt you down for that burning question.

Before we look at what information should be in an effective out-of-office message, a quick tip. Don’t create a custom rule in Mail or another email app that automatically replies to every message. It is too easy to end up sending replies to every message from a mailing list or to an address that will itself reply back, causing a mail loop where each message generates another reply, ad infinitum. Plus, the Mac has to stay turned on and active while you’re gone or else it will do nothing while you’re gone and then reply to everything when you return to work and turn it on! Instead, set up such auto-responders in the server settings for your email provider, which are better about avoiding mail loops. Here are instructions for Gmail, iCloud, Outlook.com, Spectrum, Xfinity/Comcast, and Yahoo. If you use a different email provider or an email account provided by your employer or school, check with support for additional details.

The key to writing an out-of-office message that satisfies your correspondents is to put yourself in their shoes. What information are they likely to want from you? How will they react when they learn you’re away? Do the answers to these questions vary with different audiences?

There’s no single perfect out-of-office message, but while crafting yours, we strongly recommend including—or at least considering—all the following information.

• Reason for the trip: Significant detail isn’t necessary, but there’s a big difference between being on vacation and at a conference. You may be too busy to read and reply to email quickly at the conference, but you’re probably not entirely unavailable, as you would be while canoeing in the Canadian wilderness. Being candid helps set expectations.
• Location: Sharing your rough location may be helpful if you’re semi-available but in a radically different time zone. It can also sometimes lead to happy coincidences when a contact realizes you’re in their city. But if you’re trying to unplug and get away, there’s no need to get specific.
• Availability: Some of the time, the answer is easy—you’re unavailable. But if you’re semi-available or available in case of emergency, try to set expectations appropriately for how much you want to handle versus sending to colleagues.
• Dates: Always include the date range you’ll be gone. Many things can wait, and if your correspondent sees you’ll be back on the 17th, they may just shrug and make a reminder to respond to you after that. Others will realize that they need to scramble on different plans right away.
• Alternative contacts: Who’s picking up the slack while you’re gone, or who can help in case of emergency? Put some thought into the different sets of people who send you email and write simple IF/THEN sentences directing them to the right person. “If you need help with print production, contact John Gutenberg at ppress@example.org.” Needless to say, always ask those people if they can field questions about your responsibilities first, in case they’re overscheduled or planning to be away too. If you find yourself listing lots of people, see if you can instead designate a single primary contact.
• Provide contact info: Unless you’re in a large organization with a corporate directory and don’t communicate with outsiders much, you’ll want to provide at least an email address, perhaps along with a phone number, for each of the contacts you list.
• FAQs: If many of your email questions can be answered with a pointer to a Web page, consider using such links instead of alternative contacts. Correspondents might be happier if a page provided the necessary answer rather than having to wait for a reply from another person.

Here are a few more general tips:

• Keep the message short and sweet.
• Stay positive—it’s a good opportunity to praise an assistant or colleague—and be careful with humor since you never quite know how others will take it.
• Don’t promise to reply within a particular time frame after you get back. Even if that’s your plan, airline flights can get canceled, you might return with a bad case of the flu, or something else might conspire to delay your reply.
• Edit carefully to make sure email addresses and phone numbers are correct and to eliminate typos. You don’t know who might send you email while you’re gone, and if it were the head of your company, a key supplier, or a potential investor, such mistakes wouldn’t do your career any favors.
• If your email service doesn’t let you set an automatic end date, remember to turn off your out-of-office message as soon as you get back!

Don’t you hate it when a familiar song is playing but you can’t think of what it’s called? Or worse, when you hear a new track you really like but have no one to ask what it is? Never worry about that again, thanks to your iPhone or iPad. Back in 2018, Apple bought the music identification app Shazam and has since integrated it into iOS. You can still use Shazam, but it’s easier to ask Siri, “What’s playing?” or tap the Music Recognition button in Control Center (add it in Settings > Control Center) and then let your iPhone listen to the music for a few seconds. Siri is easiest, but the Control Center button is perfect in situations where you’d prefer to keep your question quiet. The music recognition feature recognizes only recorded music—no high school glee club versions, sorry—and while not perfect, is often helpful. Tap the notification that appears to open the song in Apple Music.

A new feature of Messages in both iOS 14 and macOS 11 Big Sur is the option to pin up to nine conversations at the top of the conversation list for easy access. No longer do you have to worry about them scrolling out of sight. On an iPhone or iPad, touch and hold a conversation and tap Pin in the menu that appears; on a Mac, Control-click the conversation and choose Pin. (Remove them by repeating the action and choosing Unpin.) Each of your devices can have different conversations pinned. If you are used to scanning the left side of Messages for blue new-message indicators, also be sure to look for those blue dots amongst your pinned icons at the top of the screen. Also, note that on the Mac, it can be a little too easy to see a notification banner about a new message, switch to Messages, and type in the currently selected (but wrong) conversation.

Apple did a good job rethinking some aspects of credit card use with the Apple Card, but one omission was the inability to share it with other family members. With the new Apple Card Family, once everyone has upgraded to iOS 14.6, you can add members of your Family Sharing group to your Apple Card account as either Co-Owners or Participants. Co-Owners can merge their credit lines, manage the account together, and build credit as equals. You can also invite children over 13 and young adults as Participants. For their accounts, you can set spending limits and receive real-time notifications. Participants over 18 can build their own credit, something that can be difficult for young people. To get started, go to the Wallet app on your iPhone, open the Apple Card, tap the ••• button, tap Share My Card, follow any prompts, for the person you want to share with, and select either Co-Owner or Participant.

Although extremely uncommon, it’s not unheard of for a Mac, particularly an older model, to restart unexpectedly. If it happens once, chalk it up to cosmic rays and move on. But if it happens multiple times, try these two things right off. First, use compressed air to remove dust from cooling vents or the inside of the Mac, if you can open it up. Dust can cause heat buildup, which can in turn cause restarts. Second, try plugging the Mac into a different electric circuit or, ideally, into an uninterruptible power supply (UPS). Dirty power can provoke all sorts of undesirable behavior—including unexpected restarts—and shorten the lifespan of the Mac’s electronic components. Remember, clean air and clean power make for a happy Mac.

You’ve likely seen mention of the dispute between Apple and Facebook. It revolves around App Tracking Transparency (ATT), a technology Apple released in iOS 14.5.

The goal of ATT is to give iPhone and iPad users more control over the extent to which app makers can track their data and activities across apps and websites owned by other companies. Before App Tracking Transparency, nothing prevented companies from sucking a vast amount of data about your everyday activities and connecting it to other data to build an insanely detailed picture of who you are and what you do. Apple has written A Day in the Life of Your Data white paper and released the Tracked TV ad to give you a sense of how apps track you. We like to think of app tracking as a fleet of tiny drones constantly hovering over your head, recording your every waking moment for their corporate masters.

Facebook is particularly perturbed by the introduction of App Tracking Transparency because the company makes billions of dollars every year by gleaning as much as it can about you and then selling advertising access to you to companies that want to target people like you. For instance, Facebook knows if you’re a New York City lawyer and divorced mother of two who loves dogs, donates to the Sierra Club, and has Crohn’s disease. Although App Tracking Transparency won’t prevent Facebook from tracking your behavior across its own apps, at least it won’t be able to track you across other companies’ apps and websites.

Once you upgrade to the latest version of iOS and iPadOS, App Tracking Transparency requires that apps ask for permission to track you. However, depending on your current privacy settings, you may never see those requests. In Settings > Privacy > Tracking, if Allow Apps to Request to Track is turned off, you won’t receive any permission requests, and apps won’t be able to track you. Turn that setting on, and you’ll start getting alerts that ask for permission.

Put bluntly, there is absolutely no reason to allow any app to track you. Apple explicitly says that apps may not withhold features from those who opt out of tracking. So if you turn on the Allow Apps to Request to Track setting, tap Ask App Not to Track whenever you’re prompted. If you accidentally tap Allow, you can always go back to Settings > Privacy > Tracking and turn off the switch to rescind permission.

You might want to enable Allow Apps to Request to Track to see which apps were likely violating your privacy before and are still willing to do so even after App Tracking Transparency has exposed their sleazy business practices. Frankly, we’d encourage you to think about whether you want to use apps from such companies—perhaps the best reason to allow the requests is to identify privacy-abusing apps that you’ll then delete.

Early statistics from analytics company Flurry suggest that 94%–96% of users in the United States have opted out of app tracking, either by tapping Ask App Not to Track or by disabling the Allow Apps to Request to Track. We’re surprised the number is so low.

Home screen widgets are one of the coolest features of iOS 14. They enable apps to offer quick access to features or at-a-glance previews of changing information, such as the Weather app’s widget providing a quick look at upcoming weather. What you may not realize, however, is that an app’s widgets become available for adding to your Home screen only if you have launched the app since upgrading to iOS 14. (To see the list, press and hold on an empty part of the Home screen and then tap the + button in a top corner.) For instance, if you haven’t traveled since the pandemic started, you might not realize that the Kayak app has a handy price alert widget. Just launch the app once, and you’ll see its widgets the next time you look through the complete widget list.
