If you’re seeing Black Lines at Bottom of MacBook Pro Screen, it usually points to either a software glitch or a hardware issue like display cable damage or panel failure. Start by restarting your Mac and updating macOS to rule out temporary bugs. You can also reset the NVRAM and SMC, as these control display-related settings. If the lines persist, test in Safe Mode or connect an external display to determine whether the problem is with the screen itself.
