For me, Preview has the power I’ve ever wanted for markup & comments. Not sure if it directly edits pdfs; T’re not supposed to be edited, I was taught years ago. If I want the info from a pdf, I’ll select, copy & paste in the editor I prefer at that time, any will do. That’s not perfect, of course, but I can be resourceful. Creating a PDF on any Mac with a version of OS X is dead simple. Choose Print, then select “to pdf” in the dialog box. I used to send pdfs to our out-of-state printer who had a Windoze shop. Never a problem to him, though the editor previous to me used SOME windoze applet which sometimes was adequate, sometimes not, and often a PITA to one or the other Windoze machines.
A Windows 8 machine was too big, and I would always have to move the PDF down a level. I have used Preview on PC since version 5.0 and have been VERY happy with it. It’s a terrific tool for creating PDFs. If your only intention is to make a PDF, then nothing else matters. Preview works with all versions of Adobe PDF, for Mac, Windows, iOS, Android and Kindle.
