Autocad, 3dsMax >> windows' only softwares.
There was no compatiblitiies problem when I print cad files in printing shop. There should be an export for .dwg or any similiar extensions even if you use the not-so-common Mac cad counterpart.

I wonder, what drives you to use Mac for Architecture work? My boss is willing to buy me a workstation pc just for AutoCad, simply because the work can be used in other professional's pc.
