I belive you can get xplane9 for mac. Its a real flight sim but there is a section of models you can fly from the ground point of view. I don't know if it will see a box as a controller though. Wouldn't be much good if it doesn't. You can even fly real time weather for your area.
Im sure some one here will know if it would work. Or you could ask on there site forums. www.x-plane.org
just throwing this out, theres prob. an easyer way to go for a mac.
