Installing amnesia on mac

[tonitoni1998]

hello guys,

im new here and i hope you can help this problem?

i installed amnesia via steam on my pc and it worked fine (awesome game besides) but the ni tried to install it on my mac. everything wprked fine first. i start up the launcher, set graphics and so on... but when i hit "Play Game" the screen goes black (like it is starting) but then an error appears. " Amnesia was shut down for unknown reason" (im german so i dont know what its called in english, but it kind of says that)

please help me. i have a Macbook OS X 10.6.8 maybe its because of the graphiccard? Intel GMA 950
