Vertical lines on screen+external display stuck on apple won’t boot
No water or screen damage. Vertical lines on both computer screen and external display. I’ve tried all reset procedures. It will not boot in safe mode. Ran hardware test and it came back with no issues. Is this a gpu issue? or a kernel panic?
Can you post some pictures so we can see things. It would be helpful to see both the internal and external display at the same time (maybe a video) 在已经存在的问题里加入图片
