CrackMacHalf of my MacBook screen is black: causes and fixes
A black strip or half-black screen with the rest looking normal almost always means the panel is physically damaged in that area. It's rarely the Mac's graphics. The good news is that a Mac in this state is fully usable once you stop things from landing in the dark part.
Not ready to pay for a repair? If the damage sits along an edge, you can block off the broken part and keep using the rest.
Confirm it's the screen
- Take a screenshot (Command-Shift-3) and open it on your phone or another computer. If the screenshot looks complete, the Mac is drawing the whole picture and only the panel is failing to show it.
- Connect an external monitor. A normal picture there confirms the built-in panel is the problem.
- Watch the edge of the black area. A sharp straight edge usually means a group of dead rows or columns. A jagged edge with spidery lines means a crack.
Less common causes worth ruling out
- A display setting. Very rarely, a zoom or accessibility setting moves the picture. Check System Settings, Accessibility, Zoom, and turn it off if it's on.
- Liquid damage. Spills can kill parts of the backlight. If the area is dim rather than fully black, shine a torch at it: a faint image behind the darkness means the backlight has failed, not the panel.
- Pressure marks. A black blotch with a rainbow edge that grows over days is usually internal pressure damage. It spreads.
Your options
- Replace the display. The right call on a newer Mac you rely on. See replacement costs by route.
- Use an external monitor. Cheap and perfect at a desk. Setup is in using a MacBook with the lid closed.
- Keep using the good part of the screen. If the black area is along the left, right, bottom or top edge, the rest of the panel is still a perfectly good screen.
If the damage runs along one edge, CrackMac can keep windows, menus and the pointer off it. There's a free 30-minute trial.
What doesn't work
Pixel-fixing videos and apps are for single stuck pixels, not a black area. Lowering the resolution doesn't help either: macOS always fills the whole panel, so the dead part stays dead at any resolution.
Quick answers
Why is half my MacBook screen black but the other half works?
Usually because the panel was damaged, most often by pressure or a knock near that edge. The pixels there have lost power or signal. The Mac itself is normally fine, which you can confirm with an external monitor.
Can I keep using a MacBook if part of the screen is black?
Yes, if the black area is along an edge and the rest displays normally. The practical problem is that windows and menus still open into the black part, which a tool like CrackMac solves by keeping them on the working glass.
Damage along an edge?
CrackMac keeps windows, the menu bar and the pointer on the part of the screen that still works, and paints the dead strip black. You draw the line once, on a picture of your screen, and it stays out of your way after that.
