The default viewer for PDF documents in Mac OS X is Preview. Preview will open regular PDF documents for viewing but it will NOT display dynamic/interactive content embedded into PDF forms such as drop down menus, text editing, form numbering, form calculations and many other features which are included in SnappyForms.

For Mac users to be able to see this content, they must tell their computer to open PDF files with Adobe Reader, or Adobe Acrobat Standard, or Adobe Acrobat Professional.

To do this:

1. Select any PDF file and choose File > Get Info.
2. Choose the application with which you want to open PDF files (Adobe Reader, etc.) from the Open With menu. The programs are normally found in the Applications folder.
3. Click Change All, and then click Continue.

Additional information is available on the Adobe Web site.
