I use Aerofly RC 7 on a fairly new MAC with an M1 chip. It was downloaded from the Apple App Store. Some really strange things happened like just having a shadow on the ground and no plane to large black curtains coming out of the windmill on desert lands background. Now I can't get any of the helicopters to turn on their engines/motors. I had a version of AroFly on a Mac over ten years ago that worked fine. This one is pretty odd. I'm getting training to fly real RC and I need to practice. I'm pretty terrible right now. My instructor is very patient!
