Hello, I currently bought the complete saga of Avernum from Gog.com I bought this primarily for the scenario editor, but it appears to have either not installed along with everything else or be hidden somewhere on the mac itself. I have also tried to install the 3D avernum editor on these own forums but it says to "choose a folder" and I do not know which to put it is. I tried the Avernum Complete Saga folder with all the game launchers in it, but that did not work. Just stops with no message. Please advise how to get the scenario editor working on a mac?
