On a mac how do you change the default?

Answer 1

The default application that opens a file type can be found and changed for any file. Click the file and press command i. A window will open with information (i) about the file. One of the items is the name of the default application that will open that type of file. Click that and other apps that can open the file will be listed. You can select a new app and have it open that particular file or all the files of that type. You may need an administrator's name and password to do this.
