I am using Mac OS 10.6.8 (Snow Leopard), and I have upgraded to ID 5.5 for the 30-day trial. As I am not sure whether I want to keep it, I would like to keep ID 5 as the application associated with INDD files, as opposed to ID 5.5. Is this possible? Currently, when I click on a file to open it, it automatically opens in 5.5. I have tried to set the default application in the "Get Info" panel (please see attached screenshot), but it doesn't seem to stick. I know that a workaround is simply to open ID 5, and then open INDD files through the FILE>OPEN command, but it would be easier if I could open files directly by clicking on them in a Finder window.
Two words: Thank you!
You can also start the cs4 versions of the program first and when you double click on any creative suite files it will default to the program you have running.
Alternative would be to drag them to the required version.
