Adobe PDFViewer for Mac OS X will not run correctly on a system that doesn't meet the following requirements:
- Safari browser
- Mac OS X v10.4.3 and later
Acrobat/Reader 8 supports viewing PDF files inside Safari windows on Mac OS X, and will only run on Mac OS X 10.4.3 and later. It does not support any other browser (such as Firefox and Opera).
Note: If you don't have Acrobat or Adobe Reader, then Safari running in 10.3.9 or later will show PDFs inside its window using the Mac OS X native PDF support; this will not support many Adobe PDF workflows (such as the Collaboration feature or many Forms and Security features).
