Psychonauts on OSX 10.13.1
I purchased the DRM-Free version of the first Psychonauts through the humble store. I started to play it on a previous version of OSX and everything worked fine, but after upgrading to OSX 10.13.1 I only get a black screen after launching the game. The sound works fine and the controls seem to work too, even if I can't see what I do.
I'd like to know if my system isn't supported or if there is any way to make the game work on it.
My Graphic Card is an NVidia GeForce GT 650M.
Thanks for any help!
