You can easily set the default program to open certain file types from any “Get Info” window, from any file in Mac OS X.

It can get annoying when you double click on a jpeg from your desktop and it tries to open in Photoshop. Not only is it annoying, it can be a time waster as you close the default application and drag the file to an application on the dock.

If you want to set a default application for a certain file type to open in, control click (right click) on any file and choose “Get Info.”

Right click on any file and select 'Get Info'

In the “Get Info” options, you can easily select which application you would like to be the default for opening your file.

Select your preferred default application

After selecting the default app for the single file, apply it to all files of the same type by clicking on the “Change All” button in that same Get Info window.

Choose to apply to all files of this type
