I believe that I have successfully downloaded the base program, Cessna 172 aircraft and one scenery set of files. Apparently one way of adding scenery files to an existing program install is to use the Advanced Features on the GUI (in a Mac environment). However, the Advanced Features options is grayed out on mine. Is there a solution to this?
Also, in the documentation, is there a consolidated list of Mac keyboard commends for the latest version of Flightgear?
Thank you.
