In the Mac OS it is possible to change the default program the operating system will use to open a file when you double-click on it. After you have changed this file association, though, you may want to reset this file association back to the default program that Mac OS was configured with when it was installed. This tutorial will explain how to restore your default file associations in Mac OS.
Before changing a file extension back to its defaults, you should first enable your Mac to view file extensions so that you can find a file containing the extension you want to reset. To do this, please follow the instructions found in the tutorial How to show filename extensions on a Mac.
Once file extensions are visible on files, navigate to a file that is the type that you would like to reset back to the Mac OS defaults. Once you are at that file, right click on it and select the Get Info option as shown in the image below.

Expand the Open with: category as shown in the image above. You will now see the current program that this file type is configured to use when you double-click on it. In our example above, this means that if you double-clicked on the About Stacks.pdf file it would be open in Safari. To change it back to the default setting, you need to select the down/up arrow menu as shown in the image below.
In the drop down menu that appears you will see an application that contains the (default) phrase. This is the original default application in Mac OS for this type of file. Select it by clicking on it once. The Open With option should now be set to use the default application you selected.
Currently, only this individual file has been reset to use the default program. If you wish to make it so that all files of this type use the default application, you should now click on the Change All... button. Once you click on the Change All button, every file of this type will now be reset to use the default program. You can now close the Information screen.
