On the Rhino for Mac home page, under System Requirements, we state that the 3DConnexion SpaceNavigator is supported. We do not officially support any other 3DConnexion devices, although some users have reported that other 3DConnexion devices may partially work. We added the support for the SpaceNavigator years ago, when CAD software companies would provide the 3DConnexion device interface.
Since then, 3DConnexion has decided that they will write the device interface for all applications that support 3DConnexion devices. Since there is no publicly available SDK for Rhino for Mac, 3DConnexion is not able to write the device interface for Rhino for Mac for any of their devices that are newer than the SpaceNavigator.
