I'd like to know the answer to this question myself! You might be better off asking in the Macintosh forum though (under topic forums) I'm using a FREE subdivision modeller called Wings3d at the moment which should be ideal. But, it's still under development at the moment. You'll need to be running OSX to use it and to use the latest version you'll need OS10.2 I'm still using OS10.1.3 so I can't run the latest version and I haven't managed to import a Poser model yet! The compatability problems are known about though and if they haven't been fixed in the latest versions they should be by the final release. I think Cinema works well with Poser and I know Z-brush does but they are both pretty pricey whereas Wings costs nothing!

Hope this helps

Oh by the way, if you're creating models from scratch Wings exports in obj format, if you run the model through UVMapper it should import into Poser without problems.
