Hello, My macbook just hunge and i press the power shutdown him off when i boot it up just got blue screen with black line i think i try to reinstall the Osx and the Disk Utility can’t show up just same blu screen!
If the system appeared to be loading the OS from an external disk try connecting an external monitor to see if the display is gone. If the external shows the same blue screen you have a logic board problem.
