Stir together macadamia nut oil and melted butter in a bowl. Season with garlic, rosemary, sage, basil, thyme, salt, and pepper; stir in Parmesan cheese.
Drain corn and pat dry. Spread butter mixture evenly over each ear of corn, and place each piece on a square of aluminum foil. Tightly wrap each ear and puncture to allow excess steam to escape while grilling.
Preheat an outdoor grill for medium heat or preheat oven to 450°F.
Grill or bake the corn cobs until tender, about 20 to 30 minutes, turning frequently. Remove from the grill and check for doneness; if the corn is not done, continue cooking an additional 5 minutes.
