To change which application handles your .PDF files

By default, OS X chooses to view .pdf files with Preview ; however, you may prefer to use Adobe Acrobat to view these documents. If you double-click a PDF file and a different application opens, you can use these steps to tell Acrobat to open PDF documents:

1. Select (single-click) the PDF file in the Finder.
2. From the File File menu, choose Get Info. Get Info.
3. In the Info window that appears, click the disclosure triangle next to "Open with." "Open with."
4. Set the pop-up menu to Acrobat.
5. Click the Change All Change All button that's immediately below the pop-up menu.

These steps can be used to make any other program the default PDF reader, Acrobat is used as an example.
