I am not able to play this game on the Macbook Air 2013 model since every time I reach a certain point in Coldharbour the graphics glitch and only allow me to see a small square at the bottom left of the screen.
This is absurd since I paid $80 to play earlier. What is the point if I cannot play?

Problem is this is an issue in Apple own drivers for Intel. The developers are in contact with Apple to resolve it longterm. A fix was made for it. But suspect that a recent Apple update broke it again. So the main issue lays with Apple with the developers adding fixes for the medium term.
