In this day and age, encryption has become a necessary part of doing business for some. It might not be the most efficient way of working, but the added security gained by making use of encryption technologies more than makes up for having to take a few extra steps. Because sensitive information is not only the domain of business, this holds true for home users as well.

Depending on your platform, you might have to install third-party software to encrypt externally-attached drives, such as USB drives and memory cards. With macOS, however, you don’t. Everything you need to encrypt those drives is built right into the platform.

I want to walk you through the steps of encrypting an SD card using only the included software on a MacBook Pro, running macOS 10.15.5.

What you’ll need

As you probably expect, you’ll need an Apple machine to make this work. You’ll also need an SD card and a card reader or a USB drive.

Sonos Arc review: The all-in-one Atmos soundbar to beat

The original Sonos Playbar was a standout product when it appeared on the market in 2013: It was a big soundbar that offered both multiroom music and a simple one-cable connection to your TV. Its age has started to show in the seven years since, however, and I’ve grown to like numerous other TV speakers better, including Sonos’ own Playbase and Beam. After a couple of weeks listening to the all-new Sonos Arc, I can report Sonos has once again raised the bar. The Arc is simply one of the best soundbars you can buy.


  • Excellent sound for everything from Dolby Atmos movies to jazz piano
  • All-in-one unit doesn’t need a subwoofer
  • Feature-packed including voice assistant and multiroom music

Don’t Like

  • Single HMDI eARC port limits Atmos
  • More expensive than other single-bar competitors
  • No Bluetooth streaming

As great as the new $799 (£799, AU$1,399) Arc sounds, it’s not without its caveats. If you’re hungering for a soundbar that can do Dolby Atmos, the Sonos’ reliance on a single HDMI port means you may need a brand-spanking new TV and even a new set-top box such as the Apple TV 4K. Thankfully, the Arc sounds

Is a second stimulus check coming? The update on another round of payments for $1,200

If all goes well, Congress could start work on a second stimulus package this month.

A second stimulus check of some form is starting to take shape. Both sides of Congress and the White House have signaled a willingness to deliberate a second round of economic stimulus payments — one that could provide another round of financial relief from the coronavirus outbreak before the end of 2020.

The situation is evolving and gets confusing fast. First, there’s the Heroes Act that the Democrat-led House of Representatives passed on May 15. This is a proposal for more stimulus money, not a package that’s become law, and it’s now before the Senate. Then there’s an unnamed financial rescue act that the White House may start work on as soon as this week, according to The Wall Street Journal

That’s assuming the Senate goes ahead with a second stimulus bill at all, a decision Senate Majority Leader Mitch McConnell suggested could happen in the coming weeks, CNBC reported. If Congress does approve another coronavirus stimulus check, McConnell said, it will be the “final”

Ring’s next-gen Alarm Security Kit is a cheap, reliable DIY system

The new Alarm Security Kit is Ring’s second-gen DIY home security system. It looks very similar to the original, despite some minor hardware design tweaks, and it maintains the same $200 starting price as before. Its similarity to the previous model would annoy me if I hadn’t liked the first iteration, but it was the best affordable security system I had tested at the time. 


  • Incredibly affordable
  • Performs well
  • Easy to use

Don’t Like

  • Accessory options are limited

Now the second-gen Ring Alarm Security Kit is replacing the original version as my favorite. No, it still isn’t flashy, and I wish it offered more accessories like a glass break sensor or a key fob for arming and disarming, but this system benefits from its simplicity. It’s a good bet if you want a straightforward, affordable DIY security kit with optional professional monitoring. 

An intro to Ring’s new system

The Ring Alarm Security Kits range from a $200 (£179) five-piece kit on up to a $330 14-piece kit. I tested the $250 eight-piece kit, which includes a base station (with a built-in siren), a keypad, a range extender, a motion detector and four door/window sensors. (Different kits are offered in
