Yes, we tested Nope on both the 15" Macbook Pro and 13". Both the Nope and Nope Mini are compatible with no issues in closing the these laptops.
We use 3M VHB tape to attach the base magnet. It adheres well to the glass. The revolving magnet partially levitates so it does not touch the glass. It only holds at a small point with the base magnet. The magnets are also smooth nickel plated. The combination of smooth and light magnets plus partial levitation keeps from any scratching.
