I am afraid that you can't any more. This is mainly due to changes that Apple made (as far as I can remember).
Basically in Acrobat for Mac OR Reader for Mac, you cannot Print to PDF.
I did try a workaround a year ago of Saving the form as a Postscript file and then creating the PDF from that. However the problem is that this approach does not honour presence set to "visible (screen only)", so buttons are visible on the PDF version.
Hope that helps,
It helps MUCH!
Thank you so much...
I have a PC, so i guess i'll just have to send it to my PC and from there
print to pdf... a pain... but looks like the only solution...
Thanks once again.
