So I recently downloaded this game to learn a little more about aviation. As I loaded into the game, I thought it looked incredible. But then I went into the tutorial to learn how to control my aircraft. I was met with a fairly large crash and the background was completely blue, which prevented me from taking out the wheel chocks, so I couldn't finish the tutorial. I tried the next tutorial, and I was met with the same exact thing. Also, while I did the engine startup tutorial, the engine would not start even though I did the tutorial step by step. I am using an iMac, version 10.13.3, and FlightGear 2017.3.1. for Mac OSX. My graphics card is and Intel Iris Pro 1536 MB.I have attached an image of my problem here.
Thank you for any help.
