Just to add my vote and what a pity that is not coming soon...

Honestly MoI is pretty much the only reason I still ran windows, As Rhino OSX beta tester enissially I was really happy with the news, BUT after getting in to MoI's Hidden Secrets all I can say MoI ROCKS.

THE MORE I USE MoI THE MORE I WANT MoI ON OSX.

Now The Facts:
(Bob McNeel): We have nearly 12,000 beta users so far...and the list is still growing at a good rate...

About 60% of the beta users are current Rhino users on Windows.

Conclusion:
OSX=$$$$$$$

>>Choosing between that and adding a year's worth of modeling features to MoI, right now I have prioritized working on modeling features and adding new functionality instead of porting.
