You should now see that the folder icons for all your PDF files have switched from Preview to Adobe Reader-and when you double-click your next PDF, it will open in Reader by default.Finally, click the “Continue” button on the “Are you sure…?” confirmation prompt. Select where it currently says Preview as the default application.

When the Get Info window appears, expand the Open with section right above Preview. To make Reader the default for all PDFs on your Mac, click the “Change All” button. Right-tap (Control key + click) on the PDF. At this point, you’ve only designated Adobe Reader to be the default program for the single PDF file you’ve been tinkering with. The good news is OS X gives you power to change the default app for any format in Mac.
