Is it possible to make costum display like on newer macbooks. I have also 2016 macbook pro, I just hate the big white corners. I don’t care, if it would cost a lot to make it.
The 2013 display works on the 2013-2015. I know of no one who even attempts to repair these, they are just replaced. To eliminate the corners of the display go to a high end metal smith and see if they will make a frame for you. Or use sticky material, like is used for cover stickers, cut out rounded corners and stick it on your display.
