At Rill Architects we run ArchiCAD on Mac OS X. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

A frequently used, complicated, widely viewable object, such as a window, needs to be right in virtually every way.

The development environment gives very poor support for many of these requirements. As Archicad adds features, items are added to this list. Irritatingly, the environment has not kept up, and is way overdue for a tear-down. There is no section window, no remote stories, no graphical editing. The full features of the current GDL architecture are not supported, so we can't even imagine modern development features such as syntax coloring and auto-completion.

One of those things that bothers some people more than others.
