AST 4 Mac?

Hello, 

a moment ago I was overwhelmed with joy, seeing this possibility to create fillets with GH. But when I'm trying to use the component, my RH/GH crashes instantly (blip!).

I'm guessing that the AST is built for Windows, right? I'm on the current 5.4 MacWIP (5E44w). 

Any chance this superuseful helper can be fit for unix some day? 

Thanks, 

Vincent
