MacBook Pro Retina 15 (2012–2013) — no image

A MacBook Pro Retina 15″ with no image, or freezing while macOS starts — a very common problem in 2012 and 2013 machines, caused by… a FACTORY DEFECT in Apple hardware 🙃

At one point Apple ran a logic board replacement programme for these machines, but the basic problem was that a damaged board was swapped for one that soon failed again.

Fortunately there’s a lasting fix for this at iHelp — and this once-flagship machine is fully working again and, most importantly, shows an image ✨
