Combine two PDFs
I have found that I'm not able to view PDF files in Safari - which before just used Preview as PDF viewer (I think) but I can download the PDF file and then view it. It has something to do with both the Adobe plugin used in Safari and some issues related to Mac OS. Hope that Apple comes with an update soon. PDF Reader Pro remains the first PDF editor I have used daily to open and edit my PDF documents. PDF Reader Pro remains excellent editor for My MacBook Pro because it is fast and does not consume much memory and CPU (The OSx system of my Macbook Pro mid-2012 remains fast and powerful).
