PDF Annotation on Mac: Forget PDFPen, use Preview!

If you are looking to annotate PDF files on your Mac, you may not need to download anything. Apple’s own Preview software should get the job done; look on the right side of the toolbar (you may need to show the toolbar by clicking the button at the very top-right of the window).

Yeah, I did not realize that, so I gave the application PDFPen a try. Do not use PDFPen (or is it spelled PDF Pen? No matter). Not only does it add nothing to what Preview does, but the free version adds a huge image to ever PDF you use, and PDFPen is buggy and hangs sporadically. You have been warned.
