ReAnimator3D for Mac

From toxi.co.uk:

ReAnimator3D is a new innovative cross-platform tool for Director developers to create keyframe animations as well as offering interactive control over bones in Shockwave 3D models. ReAnimator3D (RA3D) can be used with models created in any W3D compatible modelling software with bones export, but is especially recommended to ShapeShifter3D users.
Main Features:
Intuitive, easy to learn GUI driven environment with Director style timeline
Using exported motions in own projects is as easy as using the built-in default Director bonesplayer.
The RA3D player offers a unique feature to dynamically in/exclude bones from the animation at runtime or to manually overwrite bone transforms. This way, keyframe animations don't remain hardcoded movements, but can become fully interactive and so allow for much more complex movements otherwise not possible to achieve.
ReAnimator3D is shareware. To use motions created with this tool in your own projects, you'll need to register your copy. You can order a serialnumber online for USD $50. Registered users will also receive free updates.
