I have seen this problem reported on these forums in the Windows section frequently and am unsure of its status of being fixed. I tried the method of deleting the killingfloor.ini file, but it has no effect on the problem. I am wondering if the developers have any suggestions for fixing this on the Mac or if a patch is in the works to solve this problem. I have enjoyed the game so far, but the game seems broken with this issue.
Thanks for the work on the game!
