Did it work for you? I‘m stuck in a loading screen, taking up only a quarter of my screen (top left), and on a forum I‘ve read of another guy facing that same issue…
Thanks for the guide! However I'm stuck in the loading screen right after I hit play. Tried switching between open apps, or put it to windowed mode, but nothing worked. I'm on a mid 2015 15" MBP. Any tips on how to proceed?
