I have an Apple MacBook Pro 15 inch Mid-2015 MacBookPro11,4 A1398 MJLQ2LL/A. I think it’s a Retina Unibody model. The display glass isn’t broken but the glue has come off. Can I re-glue the glass this way? Do I have to remove it as illustrated above? Or can I just re-glue it by warming it up? I’m afraid the adhesive is on the whole display surface.
