I have the same issue with these games. Idk why it happened so I decided to find other similar games. It's an often issue with drivers on Macs, that's all I know. But it helped me to find a lot of other games, especially educational ones. To be honest, I don't like studying at my uni at all but these learning games for teenagers I found on this one website were really nice. If you found any suggestions, so share them with me, but if not, there are a lot of great games on the internet!
