No idea whether I have chosen the right picture or subject, but I want to be able to open pdf's on my desktop (iMac). I could not open a pdf and installed Adobe, but after that still could not open the document. On your website I get extremely puzzled about what to do. I hope you can advise me about simply how to open a pdf document on my computer. Kind regards, Jaco de Kraker, firstname.lastname@example.org.
