Problem while opening Amnesia

[Mudbill]

I think an important factor can be where the game was bought from. If it was from Steam, I doubt this method would work since you're not allowed to run the game outside Steam. I think the poster of the tutorial was using the Mac App Store version, or perhaps the retail one.

As he stated, it's by no means a permanent fix. Unfortunately, this issue hasn't been fixed yet officially, so I guess people are lucky to get the game running at all.

And just for reference, I installed Mavericks at one point and the game was working fine for me. I was using the Steam version. I didn't try it for a longer period though, since I shortly reverted back to Mountain Lion, so I can't say for sure if the Steam version at some point stopped working.
