That's interesting, Bichworth, because I asked earlier in several places about allocating memory for Mac OSX. What I was told was that OSX automatically gives you the memory you need, and allocation is no longer necessary like it was with OS9. That kind of makes sense, because I've been using Daz3D figures that would probably cause a crash with the default memory setting. The other thing I heard is that Poser in MacOSX uses virtual memory a lot. So if you don't have sufficient free space on your harddrive (3 gig or more), then you might be having problems for that reason.
