good news: You can protect your device pretty easily — just install the
latest software update. Rachel Rothman, Chief Technologist of the Good Housekeeping Institute,
explains that these updates are designed to improve known performance,
stability or security issues like this one. And being lazy about keeping
up with updates just exposes you even more to danger: "Once a software
update is pushed, it makes the machines even more vulnerable to hackers
if you don't update, since the issue is now in public domain."

To update your phone, go to Settings > General > Software Update, then tap "Download" and "Install."

And to update your desktop or laptop OS, click on the "Apple" menu and select "Software Update."

That's it. Now you won't have to hold your breath every time you receive a text or turn on your laptop.
