After reading this I easily changed the default program that a file would open with in mac os x. Â Basically, this is what happens when a file is double clicked, there is a default program that is associated with that type or file or file extension. Â I found it annoying that files like a jpeg or .csv would open with Photoshop or Numbers when I wanted them to open with Preview or Exel.
The basics to change this are to right click the file, select get info, then click the drop down for Open With, then select the program you want this file to open with by default, then click the change all button. Â Then you are done.
