Hi, as a newbie to this forum, can any Mac users tell me how to open an application so that I can use this software.
I'm using an iMac G5 with OSX10.4.10 installed. When I click on the icon on my screen, I get a windo advising 'There is no default application to open the document 'TerragenMac_v09.sit' with the choice buttons of Cancel or Choose Application. When I click Choose application, a window similar to the Finder window opens titled Choose application. Some of the applications are greyed out. Where do I go from there?
