How to Update MacOS

A MacOS update can be an easy thing to ignore, or miss entirely, but these updates are important to the overall functionality of your Mac. Sometimes you'll get a notification on your screen letting you know about an available Mac update that you can auto schedule, but other times you might have (or want) to check for updates manually. Here's how to update a MacBook or iMac.
