I have a client with a Mac Book Pro (10.8.2) and we couldn't get FileMaker Pro 12v1 to install, it just would crash on install. I got a 12v3 version finally to install and it seemed to be working. But we found out it would still crash whenever printing to PDF or Save As Records PDF. The Finder was defaulting to Preview for PDFs, so we downloaded the latest Acrobat and installed it and set it as the PDF default. FileMaker still crashes when saving to PDF. We have logged in as a different user with Admin privileges and tried it and it crashes when saving as PDF. We can open up other applications like Apple Mail and Print to PDF and it works just fine. I'm getting ready to just do a reinstall of the operating system, but I thought I would check if this rings a bell to anyone else. I thought I would ask here since the other applications seem to not have this same problem that FileMaker is having. Thanks for any suggestions.
