I get a rattling noise like something is loose in my touchbar 15 inch macbook pro when i shake it from left or right to the right or left respectively. Do you have the same issue also in your new macbook pro?
Just figure it out.. if you close the lid and shake it it still rattles.. keep closed the lid and press a little bit hard above the apple logo.. shake it again no rattling.. wtf is inside or above the apple logo in the display????
