Tried to replicate on my Windows build, both with a win32 and x64 build, but it worked in both. The only thing that comes to mind is that we've got a couple of pending bugs for AGS not working on foreign systems like Symbion and AmigaOS4. Is Dead Dimension the only game you tried, or do other games crash as well?

In either case, there's not much I can do further, unfortunately, since I can't replicate any problem. Maybe someone else with a Mac that does their own builds might be able to likewise try and see if they can replicate the problem, and if so, investigate the problem.

I can't reproduce the problem on the current build, so I guess something fixed it, or it was a fluke error.
