I installed Condor a while ago to see if it would run on CrossOver Games 8.1.3. Turns out it does, but only partly: could install, but not select anything but the missions in Flying School (I usually select winch launch to then go into free flight).
If I select Free Flight from the main menu, i get 'Error Creating Direct3D framework for PlaneViewer: try unchecking Setup> graphics>try stencil buffer'. Which then doesn't help solve the problem. In some cases, it also stops loading with a FP Division By Zero error (possibly audio-related - not sure).
Free flight from Flight School works fine, though. Once the sim loads, runs pretty well on my 2009-era Mac mini under OS X 10.6.3.
