Resposta para "Vertical line problem on retina screen"I have the same problem on my MacBook Pro 2019 model. I had this problem on an earlier Mac desktop too. A vertical green line to the left of the screen, then a vertical red line next to it - now entire screen flickers with about 15 replicas of everything on the desktop overlayed on top of each other. you people saying you have this issue with all the models in between it seems and some are, rightly so, peeved at Apple's Forced Obsolescence. I've just had enough. I'm looking elsewhere…maybe Hauwei laptops. This Neoliberal/Crony nonsense has got to stop..and we must stop forking out hard-earned cash for a product which is designed to fail in a year or more's time!
