Notes
There is no Sketchup import add-on available for the Intel Mac (MacTel) platform. Sketchup Framework - the interface between the SketchUp file and the Archicad add-on - is not yet released by Google for the Intel Mac platform, therefore currently it is technically impossible to develop the Add-On. For AC 10 there will be no add-on available for the PPC Mac platform either.
