In many ways, Macs are built for convenience: They have backlit keyboards, there's a variety of ways to take and save screenshots, and they come with a wide assortment of shortcuts that can speed up your work.
But like all devices, they also require updates from time to time. And although updates can be annoying and time-consuming – Who hasn't put off an update until the very last moment? – they're also incredibly important.
An outdated Mac is more susceptible to bugs, crashes, and even viruses (yes, Macs can get them too). And if you leave updates waiting for too long, your favorite apps might stop working altogether.
In October 2021, Apple released macOS Monterey, the latest version of its famous operating system. And if you're currently working on a Mac, now is a good time to update your computer.
How to update your Mac
There are two major ways to update your Mac, and which one you use will depend on what macOS version you're currently running.

From the above screen, you'll be given the option to update your Mac. Any Mac computer released in 2012 or later should be able to update to at least macOS Catalina. If your Mac is so old that it can't even do that, it might be time to buy a new model.
And, for future reference, don't worry about accepting an update and then having your computer unexpectedly restart - you'll be notified beforehand if a restart is required.
