Set the Default PDF Viewer in Mac OS X Back to Preview
If you’ve downloaded Adobe Acrobat on the Mac you’ve probably discovered that it takes over Preview as the default PDF viewer in OS X, which is annoying because Acrobat is slow to load and a fairly bloated application. There’s little need to use Acrobat Reader as the way to view PDF files, so here’s how to change it back to Preview.
Change the Default PDF Viewer in Mac OS X
- From the Mac OS X desktop, find a PDF file and hit Command+i to “Get Info” on the file
- Click on the arrow next to “Open with:” to expand and access the default application list
- Click the pull-down menu and choose “Preview” from the list, or if it’s not visible, navigate to it by choosing “Other”
- With Preview.app selected, click on the “Change All” button
This will restore the leaner and very capable Preview app as the default PDF viewer in OS X and prevent the lengthy launch of Acrobat anytime a PDF is opened. This tip will be of less use if you need the full functioned Acrobat version, but for the average person just looking to quickly open pdf docs this can be a significant time saver.
