A friend recently got in touch with me about a troubling problem. When he received texts on his iPhone, Messages displayed notifications for messages from everyone…except his wife! Needless to say, this was a problem. Since notifications appeared correctly for other people, it wasn’t related to overall settings. It turned out that he—or someone else, or iOS gremlins—had inadvertently enabled the Hide Alerts switch for the Messages conversation with his wife. To fix it, all he had to do was display the conversation in Messages, tap the” i” button at the upper right, and disable Hide Alerts. (In the Mac version of Messages, click the Details button and look for the Do Not Disturb check box.) It’s a good feature designed to let you mute a chatty group conversation, but it can cause stress if applied to the wrong conversation accidentally.

The next time you notice missing messages, check those settings.

Now that Apple has discontinued the Time Capsule how are you backing up your Mac? While I still use legacy Apple gear on my Eero network to emulate a Time Capsule, I also have a drive on my desk at the office that I use for my most secure back up. As a friend in the business would say “ May you have a thousand back-ups and never need one!”

Backing up your Mac is like flossing your teeth: everyone knows they should do it every night, but too many people never get around to it. Unlike flossing, once you set up backups, they don’t require daily attention. And turning on Apple’s Time Machine backup feature is easy—simply open System Preferences > Time Machine, click Select Backup Disk, and pick a hard drive to hold your backups.

Ah, but here’s the rub. If you don’t have an appropriate hard drive, you will need to get one, and there are tons of options. Here’s our rundown of what to look for, with added recommendations.

How Much Space Do You Need?

The first question when looking for a backup drive is how much data it needs to hold. You could put a lot of effort into figuring this out, but for most people, the answer simple. Buy the largest drive you can reasonably afford, as long as it will hold at least two to three times as much data as you have on your Mac or anticipate creating in the near future.

Say you have a MacBook Pro with a 512 GB SSD. You could get by with a 1 TB backup drive, which would be twice as large as your internal drive. But if a 1 TB drive costs $100 and a 2 TB drive costs $130, it’s worth the extra $30 to double the available space!

How Will You Connect It to Your Mac?

With external hard drives, you need to match the ports on your Mac with the ports on the drive. That might sound tricky, what with USB 3, FireWire, USB-C, and Thunderbolt. Luckily, for most people, the right choice is simple: a drive that supports USB 3. They’re inexpensive and plenty fast for backups.
Nearly every Mac sold since 2012 supports USB 3, either via the familiar USB-A port or the newer USB-C/Thunderbolt 3 port. If your Mac has only USB-C ports—as would be the case if you have either a MacBook or a recent MacBook Pro—you may also need an adapter cable that’s USB-A on one end and USB-C on the other, although many drives now also include USB-C support.

What Type of Drive Should You Buy?

Inside the case, an external hard drive contains either a 2.5-inch or 3.5-inch drive mechanism.
2.5-inch drives are smaller, more portable, and usually bus-powered, meaning they get power from your computer instead of from a wall outlet, making them easier to hook up and use. They’re also designed to be more rugged. On the downside, they cost more per gigabyte, max out at 5 TB in size, and are often slower.

3.5-inch drives usually need to be plugged in to power, and they’re less appropriate to carry around. However, they cost less per gigabyte and can be bought easily in sizes up to 8 TB. They also tend to support more connection types, making them more flexible.

If you work mostly on a notebook Mac and lead a mobile lifestyle, carrying a bus-powered 2.5-inch drive ensures you can back up while traveling. Such a drive might also be best for a MacBook-equipped college student. However, if your Mac mostly sits on a desk or you bring your laptop back to the same place every night, you’ll likely be better served by a 3.5-inch drive—they’re faster, cheaper, and store more data.

Putting It All Together

Since the hard drive mechanisms are made by a relatively small number companies, the differences between external drives mostly come down to the price, industrial design, and extra ports.
