On my Windows PC everything it working fine win using Wikitude Camera and Image Tracker. When a play using my webcam I see what the webcam is viewing. On my Mac the game window is just black. I have checked the Wikitude Camera Script and the Webcam is recognized. I Switched to viewing thought my iPhone and my iPhone show Unity is using my camera on my phone but the Game view is still black. I have made sure I am using the same Unity and SDK between my Mac and PC.
