Mac users have access to as many PDF editors as Windows, and so you can actually edit PDFs on your Mac pretty easily. There are both built-in as well as third-party methods to markup a PDF on Mac.
The easiest way to play around with PDF files on a Mac is to use the Preview app. This app is actually the default PDF viewer on your Mac, and you can use the app to edit your PDF files as well. This means, without using a third-party app, you can make changes to your PDF files on your macOS-based computer.
Most Preview versions offer pretty much the same set of features, and so you can markup your PDF regardless of what version of macOS or Preview you are currently running. However, it is good if you are running the latest version of these items.
