 I'm biased, but I think Avogadro http://avogadro.openmolecules.net/ is the best molecule
 builder and certainly can deal with biomolecules. I develop Avogadro on the Mac,
 and there are nightly builds of both "stable" and
 "development" versions:
 http://avogadro.openmolecules.net/nightly/mac/
 Avogadro for Mac includes support for drag-and-drop of files, double-click in
 the Finder... all the usual goodies.
 Best regards,

 P.S. I do like Aten -- I think it's very good for building repeating systems
 like crystals, nanotubes, solvent for MD, etc.
