How to make a PDF file in OS X
Unlike Windows, Macs come with a way for the user to make their own PDF file out of the box. Â One can make virtually any type of printable document in to a PDF file with these simple steps:
1. Â Go to a document that you wish to make a PDF file out of.
2.  Select FILE > PRINT (or [Command+P]).
3. Â The print window will open.
4. Â On the lower-left corner of the window is a button that says PDF.
5.  Click it, and then choose Save as PDF.
6. Â Another window will open asking for a filename for the PDF.
7.  Name the file, then click Save.
8. Â That's it.
