Change the Default App a File Opens with on a Mac
Feb 1, 2011 - 8 Comments

You can change an individual files default application by doing the following from the Mac Finder:
- From the Finder, select the file that you want to adjust
- Hit Command+i to “Get Info” on the file
- Click to expand the “Open with” section within that files info screen
- From the pull down menu, select the application you want to open this specific file with
- Close the Get Info window
This will only change the default behavior of that specific file. If you click the “Change All” button you will change that file types association across Mac OS X, causing all instances of that file to open in the application you chose.
