Hi. I opened my MacBook Pro this morning and when I turned it on I saw my screen full of horizontal symmetric black lines covering literally everything . The pc wasn’t damaged in any way, didn’t fall, didn’t hit anything, didn’t touch water. Does anyone know what the issue can be and how to fix it? Thank you 🙏🏻

It's possible that your MacBook Pro is experiencing a hardware issue with the display or the graphics card. The black lines on the screen could be caused by a variety of factors, such as a loose connection or a malfunctioning component.
To troubleshoot the issue, you can try a few steps:
1. Reset the PRAM and SMC. This can help resolve some display issues. Here's how to do it:
- Shut down your MacBook Pro.
- Hold down the Command + Option + P + R keys together.
- Turn on your MacBook Pro and keep holding the keys until you hear the startup sound twice.
- Release the keys and let your MacBook Pro start up normally.
2. Boot your MacBook Pro in safe mode. This will load only the basic system files and drivers, which can help determine if the issue is software-related. Here's how to do it:
- Shut down your MacBook Pro.
- Press the power button to turn on your MacBook Pro.
- Immediately hold down the Shift key.
- Release the Shift key when you see the Apple logo.
3. Connect your MacBook Pro to an external display. This can help determine if the issue is with the display or the graphics card. If the external display works fine, then the problem is likely with the MacBook Pro's display. If the external display also shows the black lines, then the issue may be with the graphics card.
If none of these steps resolve the issue, it's recommended to take your MacBook Pro to an authorized Apple service provider or Apple store for further diagnosis and repair.
I have had this happening to 2 Macbook Pro's within 6 months. Both handled with care. One is a 2021 Macbook Pro at 4 KUSD. The fact that Apple products command high price tags is manageable since I am not forced to buy them. The fact that they turn out to be **once I have paid 2x vs. a PC is something completely different.

I am facing the same problem in my MacBook Pro 2019 16" , it started today. The lines disappears when I close the screen to 45 degrees and appears again if the angle is >45 degrees. I could see thousands of Mac users facing the same problem, hardware replacement seems too expensive. Is there any other working solution ?
I've been experiencing the same issue for several months now. I’m using a MacBook Pro 2017. I'm not sure if it's related to a recent OS update, the issue comes after updating new OS. I've tried resetting the SMC, PRAM, and NVRAM, but the issue persists. I consulted someone, and they suggested that my screen might be broken, but I don't think that’s the case—it seems like either a hardware or software issue.
The problem is that black horizontal lines only appear on the screen when it's static, meaning when I'm not using the keyboard or mouse. As soon as I interact with the keyboard or move the mouse, the black lines gradually disappear. If I connect an external monitor, the black horizontal lines also disappear completely.
I'm really confused and not sure what the problem is. Now I can't bring laptop to use anywhere since I have to connected it with external monitor to work.
Can anyone help with a solution?
I have a Macbook Air 15inch M3, purchased from Costco in May of 2024. It has developed the weird horizontal lines that cover the entire screen and overlay all windows. The 45 degree angle thing seems to make them unable for me to see, but that might just be due to that being an unsuitable viewing angle--meaning I can't see anything at that angle really, so not a big surprise that I can't see the faint, corrugated lines that cover my screen. It makes watching anything a bit annoying, as they appear everywhere and almost make the images look like corduroy patterned. I have not moved my computer from my desk in over a month, and I am careful with it when I do move it / take it with me. I am not sure when exactly this started, but it seems like maybe it came with my last major update to Sequoia.
Same here on M1-Pro 2021 14" Macbook Pro bought in 2022. Opened the computer last night, no water, never dropped it, always try to keep the dust out, and I find this.
The "ME TOO" button show 1966 people having the same issue, this is completely unacceptable and for me it's the last straw with Apple computers.. never going to buy one again. Apple needs to own up to their product defects and start rewarding their customers for spending the amount of money they're asking, instead of profiting off every single defect. A complete disgrace
You obviously don't understand what the issue is.
There are black lines around my I phone & cannot press any buttons
Computer screen filled with vibrating lines
Apple, how are you not going to respond here with a solution??
I just got the same issue today and the Apple Service asked me to return it for repair. But I want to know what happened to it...
omg i just got the same issue, woke up this morning and now I have this black line starting from the side of my screen. Did apple fix your issue?
I have totally the same situation today.
Did you manage to fix the problem?
same
I had a similar experience, only worse. I was told my tiny cracks were covered so I left the laptop to be repaired. Got a call the next day saying - Sorry, after tax, it will be $800.
same issue to my mac book pro 2019.
