Just purchased and installed the game on Mac, however when I try to launch the game, it launches the Terminal with this message:

It then appears with the error "Psychonauts quit unexpectedly."

Can anyone please give me any advice on what this problem could be relating to or if there's any possible solutions? My Mac OS is currently X Yosemite Version 10.10.5. Should I update this?

Thank you in advice for your help.

I'm having the identical problem in linux mint. except that the terminal output concludes with "core dumped."

I have the same problem on Mac OS 10.14.5,
13 ", 3.3 GHz, 16GB, Irisi Plus Graphics 650
