You can create pdfs from many other applications, such as Word and graphics programs. Adobe’s Acrobat Professional is its suite for PDF publishing. It’s available on the Mac for $160.
Re: creating PDFs on Macs
Every application on an OSX Mac can create a PDF file because it’s built into the OS. PDF creation is not application dependent. Adobe’s software is not necessary on a Mac. Mac created PDFs can be sent to publishing houses as easily as can Adobe’s.
