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An outdated Mac is more susceptible to bugs, crashes, and even viruses (yes, Macs can get them too).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 November 2020, Apple released macOS Big Sur, 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 computer

There are two major ways to update your Mac, and which one you use will depend on what macOS version you're currently running. For information on how to check which macOS version you currently have, read our article, 'How to check which version of macOS your Mac computer is running and check for new updates.'

Before going forward with updates, it's a good idea to backup your computer to ensure no data is lost in the process. You'll also need to be connected to the internet.

After that, keep in mind that the updates may take several minutes to install, depending on how many of your apps are due for updates.

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.
