The Adobe PDF Printer is not available or is unusable in Mac OS X Snow Leopard (v10.6). This situation is due to security features in Snow Leopard that disable the Adobe PDF Printer. Adobe Acrobat 9.1 Pro removes the Adobe PDF Printer and adds a new Save As Adobe PDF command. Customers using earlier versions of Adobe Acrobat in Snow Leopard cannot use the Adobe PDF Printer.
If you upgrade from Mac OS X Leopard (v10.5) to Mac OS X Snow Leopard (v10.6), the Adobe PDF Printer is not removed
Technical changes in Mac OS X Snow Leopard (v10.6) prevent Adobe from delivering a PostScript-based printer module. However, the new PDF workflow takes advantage of the PDF-based printing architecture already present in Mac OS X. By choosing Save As Adobe PDF from the PDF menu, Apple-based PDFs are converted to Adobe-quality PDFs using your JobOption settings.
The benefits of a PDF-to-PDF print workflow include the following:
- Better performance
- Higher quality PDFs
- The ability to create PDFs that are compliant with Standards, such as PDF/X and PDF/A
- The potential for adding functionality to PDFs, such as bookmarks, hyperlinks and watermarks
Users of non-Adobe PostScript-based publishing applications cannot print directly to Adobe PDF, and must use another PDF creation method.
Some versions of some Adobe Products, such as InDesign and Illustrator CS4 or CS5, do not support use of the PDF menu in the Mac OS X print dialog box. For those cases, either save as (Illustrator) or export (InDesign) to a PDF file, or print to PostScript® file and open that file with Distiller, Acrobat Professional, or Apple's Preview application. For more information see "Error, 'The Save as PDF options in the Printer dialog are not supported' trying to create PDF from InDesign or Illustrator from Mac OS 10.6 Print dialog." (cpsid_85257).
