Issues with Save as PDF options
When you use InDesign or Illustrator on Mac OS 10.6 and later, the Adobe PDF printer is not listed under the available printers. Or, it is if available, it doesn't create a PDF as expected. When you choose Save As Adobe PDF from the Print dialog box, an error such as the following appears:
"The Save as PDF option in the Printer dialog is not supported."
Solution: Print as a PostScript file, and then convert the file to a PDF
If you want to use Acrobat PPD with this method, follow the instructions in Install Adobe Acrobat PPD.
From the Printer list, select PostScript File.
Set any other settings as desired and select Print.
You can save the file to your preferred location.
Open the PostScript file with Adobe Acrobat Distiller or Apple's Preview application to convert it to a PDF.
Install Adobe Acrobat PPD
Follow these steps if you want to have the Acrobat 9 PPD appear in the PPD pop-up menu. The Acrobat 9 PPD supports custom page sizes, which are often necessary when using this workflow with the Print Booklet feature in InDesign.
InDesign CS5 is used as an example here. For other versions, adjust the version number in the folder paths.
Go to /Applications/Adobe Indesign CS5/Presets/.
Create a folder named PPDs (the folder name is case-sensitive).
Place a copy of the downloaded PPD into the folder you created in step 3.
Most applications can take advantage of the new Create Adobe PDF from the PDF menu in the Mac OS print dialog box. However, InDesign and Illustrator sometimes don't support this feature, depending on the version you are using. In this case, print to a PostScript file, and use Distiller or Apple Preview to convert the file to PDF.
