Rhino render- not assigning materials

The basic rhino render in the latest mac version doesn’t appear to work- is this the case? I can’t assign materials to layers or to objects. I can apply a material via the object however can’t match to other objects. Any help you can give is appreciated.

To assign a material to an object, select the object, then click the Material tab in Object Properties and select Object in the radio buttons. Assigning a material to a layer and Match are not yet implemented.
