I saw no way to register the free copy of c7pro at daz, I saw no download link for c7pro content,
and mac version of c7pro on the 3dartist disk contains incomplete version of app installer package.
this means that daz would hafta allow us to download the full c7pro app in order for it to contain the
native content in the app installer package.  otherwise, mac users with knowledge of editing
the application package may be able to fix it up right, using the windows carraranativecontent.exe,
assuming they can install exe files in OS X.  however, it does work o.k. without doing that,
so it's still a good deal for $15 american IMVHO.  but I'd advise waiting for 3dworld instead.
