Hi Mark,

Thank you very much for responding.

I don't think I am using any Win-specific plug-ins in my scene. And since I don't have plug-ins installed on the Mac, wouldn't the scene give me an error at load time, if it required plug-ins which were not there?

True, the scenes in question are rather heavy for rendering, they take over 18 hours to render on my PC, and the Mac Carrara did render a much lighter scene without a problem, but I still don't see the reason to crush on the heavies scene when it renders fine on PC.

I saved the crush report, but I don't see anything there, that would clearly raise a red flag...

I am just not sure whether it is something that should be files as a bug report, or it is just me, doing something stupid.

Again, thank you very much for your help.
