Hello friends, it turns out that they changed the back panel of my Mac mini and when the Apple Store delivered it to me, the back part where the ports are located came with a kind of plastic covering that now when I removed it, it left me with some glue stains. I tried removing them with a slightly damp microfiber cloth but they don't come off. Would anyone know how to remove them? Or would I have to go back to the Apple Store? Thank you
