I have simon the sorcerer which i have got working on my ipad using the scummvm build but when i run it on my Macbook it starts then just crashes scummvm out without any error. You just see the first screen from Simon the Sorcerer and then thats it..
The only thing I can think of that might be causing trouble are the new settings for MIDI devices. But I don't know if problems with that would allow you to get even as far as the first screen.
