Chop macadamia nuts in a food processor. Reserve 3 tablespoons and set aside.
Place remaining chopped nuts in a medium-size bowl and add the cheeses. Blend. Add the orange rind and Grand Marnier. Blend well. Divide mixture in half and spoon each into a rectangle of plastic wrap. Fold wrap around mixture and form into logs. Refrigerate until firm.
When ready to serve, remove plastic and sprinkle with remaining nuts. This can be frozen and gets tastier by the day. Makes two cheese logs, about a pound each.
