Installed fine using instructions from the main Neverwinter Nights product board. Runs great, at full performance on MacBook hardware. Does not support pixel-shading (hardware issue).
Game runs smoothly, only one graphics bug so far, where screen will go blank for a few seconds and then come back (I always just pause the game when this happens). I believe it has to do with rotating the camera.
I definitely recommend installing the update by downloading the critical rebuild as mentioned in the other forum, and installing into the same bottle.
Happy playing!
