I have a dead 2015 15 inch retina MacBook Pro. The display is fine. The display has the same video connector as well as iSight camera connector etc. All the cables match up perfectly on my one year older 2014 Retina 15 inch but when I powered on I’m not getting any kind of image on the 2014. Is this display not compatible with the 2014 inch model that’s only one year older? Again all the cables fit perfectly and fits just like the original so I’m assuming that it must not be possible even though the cables fit securely and are of the same pin count etc. and plug right in. Can anyone shed any light on this for me please?
Sorry Apple messed you up! They changed things. You must use the MacBook Pro 15" Retina (Mid 2015) Display Assembly display for your Mid 2015 system the 2014 display is not compatible!
