In today’s world, there’s no reason to remember our contacts’ phone numbers or email addresses—that’s a job for our Macs, iPhones, and iPads. This sort of data is so core to using digital devices that Apple has long provided an ecosystem-wide solution in the form of Contacts and syncing through iCloud.

Unfortunately, it’s all too common to end up with multiple cards for the same person in Contacts, either precise duplicates or versions that contain different details. Further muddying the situation, many of us have multiple contact accounts—such as from Google or Microsoft Exchange—and some contacts may be duplicated across several accounts.

For several decades, Russia has targeted a wide variety of cyberattacks at countries with which it has had disputes. That includes the United States and other Western nations, which have recently levied unprecedented sanctions against Russia after it invaded Ukraine. President Biden has warned that “Russia could conduct malicious cyber activity against the United States” in response, encouraging the private sector to increase the protection of systems and networks. This isn’t theoretical—the US Cybersecurity & Infrastructure Security Agency lists numerous such attacks in the last five years.

It’s tempting to think that your business is too small or unimportant to be targeted in a Russian cyberattack. While that may be true of direct infiltration by individual Russian hackers, many cyberattacks are carried out indiscriminately by bots—the ultimate is the DDoS (distributed denial of service) attack that uses compromised computers and Internet-of-things devices to flood a targeted server or company with an unmanageable amount of random Internet traffic. Plus, a common hacking approach is to compromise an account on one seemingly unrelated system as a stepping stone to another, more secure system.

Over the past few months, there has been a spate of media reports about how people may have been tracked without their knowledge using AirTags, Apple’s elegant location trackers. Like many mainstream media forays into the tech world, the reports are often short on detail and sometimes unclear on the reality of how the AirTags work. Nor is it clear that there have been many successful cases of AirTag abuse, but the mere fact that people are trying to use AirTags to stalk others is concerning.

Apple put significant effort into preventing such abuses, revolving around three features:

Normally, when you rotate an iPad, the screen happily flips from portrait (vertical) to landscape (horizontal) orientation as appropriate. Rotating an iPhone has the same effect in some apps, though many are written to work only in one orientation. If you ever end up in a situation where your device’s screen doesn’t rotate when you think it should, the reason is likely that Rotation Lock has been turned on in Control Center. Swipe down from the top-right corner of your screen (or up from the bottom of the screen on a Touch ID iPhone) and disable the Rotation Lock button. You can turn it on again later if you ever want to prevent the screen from rotating temporarily.

We’ve become accustomed to our iPhones and iPads switching into Low Power Mode to preserve battery life, and you can enable it manually if you want to reduce power usage for a day. New in macOS 12 Monterey for the MacBook Air and MacBook Pro is a similar feature, though you must enable it manually. Open System Preferences > Battery, click Battery in the sidebar, and select Low Power Mode. It reduces the screen brightness automatically and may decrease CPU performance. Make sure to turn it off once you don’t need it anymore.

We all have old electronics squirreled away in our drawers and closets. It’s hard to admit that a computer, phone, or peripheral that cost hundreds or even thousands of dollars years ago has little or no value. That’s doubly true if it doesn’t work anymore. Once you’ve decided to get rid of that PowerBook 520 from the 1990s or your first digital camera from 2004, resist the urge to toss it in the trash.

In some places, it’s illegal to throw out electronics because they tend to contain heavy metals like mercury, lead, and lithium, plus other hazardous materials that can pollute the air if incinerated or contaminate the ecosystem if buried in landfills. Even if dumping e-waste is not actively illegal in your area, it’s a terrible thing to do. So what can you do instead?
