Markup is one of the more useful little tools that Apple has brought to iOS and macOS in recent years. It's great for making notes on your own documents, but it can be especially useful for files that you send to others. Whether it's a PDF document, a photo, or something else, adding your own thoughts to an existing file can be very helpful to other people viewing it.
One of the more useful aspects of the Markup tools in macOS is that you can use them right before you send someone an attachment via email, right from the Mail app. Whether you need to write out some notes, highlight something with shapes, or zoom in on a particular detail, you can do that all without heading to another app.
