Please could someone provide some guidance on what’s wrong and needs to be replaced in my Mac. One minute it’s working fine with no problems. I then either get screen flicker/black screen/blue screen. It sometimes then restarts itself? Sometimes too it just keeps restarting When it’s on the Apple screen and never reach the desktop.
On this model your most probable issue is a GPU failure. This is a very well know issue on this model. Apple had a repair program on it (now expired) https://9to5mac.com/2013/08/16/apple-ope… Here’s a video on replacing it: https://www.youtube.com/watch?v=5aQPPaec…
