My mom is still using MS office 2008 especially Entourage on her new MacBook Air laptop. I have tried to get her to upgrade but to no success so far. Recently she has been unable to open PDF file attachments on her MacBook with Entourage, does anyone know why? PDF files open like a charm in Apple Mail and I do not know why she won't move over to that. She wont buy MS Office 2016, so I guess the next version of Mac OS Apple will kill support for older apps like Office 2008.
