I want to know, is there a hardware problem or a software problem?
- While my OS is not up to date (I am still on High Sierra due to paranoia on other issues and not wanting to break stuff again) my coworker who is having the same flickering issue is fully updated. I've read that the only way to update a graphics card driver on a mac is to update the OS.

Part 1. Why Your MacBook Pro Screen Is Flickering?
There are lots of reasons for why your MacBook Pro screen is flickering. Maybe you had spilled some liquid on it, maybe not. In some cases, it just happens. That's the scary part because it's the last thing you would expect from an Apple product.
When you're trying to find out the reasons why your screen keeps flickering, you're looking at the two major components of your MacBook and these are the hardware and the software. There's definitely something happening between that's making your screen flicker. That's for sure. Of course, that's a very broad way of looking at the issue but nonetheless, it starts there.
Compatibility Issue with Graphics Card
Truth be told, it happens, whether it's an Apple or not. There are a couple of reasons for that. For starters, there could be a compatibility issue with your graphics card. In most cases when the issue arises, the user is watching a video.
For example, you could be watching a movie on your MacBook and all of a sudden, the screen starts to flicker. If that same issue keeps on happening, then there probably is a compatibility issue with the graphics card.
Water Damage
In some cases, well, the screen flicker could be a cause of liquid spillage leading to water damage. That is, of course, if the spilled liquid was water. If it were something else, it would be worse than just the screen flicker. Here's the thing, even if you had dried out the water from your Mac with a high-powered fan, there could be a liquid residue that could corrode the inside of your Mac.
Software Update
In some cases, the issue arises soon after an update. In this case, it's a compatibility issue with the software. It has happened to some Mac users upgrading to macOS 10.14.

Free DownloadScreen flickering is perhaps the most annoying problem that can occur with a MacBook. If you have this problem, you can continue to work. However, even a short time spent behind such a screen causes discomfort for the eyes. Starting from dryness, and up to pain in the eyes. Therefore, you should never use a MacBook with a flickering screen.
Problems can be either software or hardware. It should be noted that new generations of the MacBook are becoming more reliable, and macOS updates are stable. Screen problems are becoming less common. But still happen.
Consider some of the major hardware causes that may cause your MacBook Pro Screen flickering:
- The problem with the screen. It can be broken off, frayed, and simply torn off. Most often, this happens during mechanical impacts on the MacBook – bumps, falls from a height. In addition to the loop itself, the contact of the loop with the corresponding connector may be damaged. Correction will require replacement of the loop;
- Decoder malfunction. This is a serious problem that will require replacement of the entire matrix;
- Violation of the screen backlight. The problem is not serious and can be easily fixed in the service center;
- The problem is at the motherboard parts. Perhaps the failure of the entire motherboard, or there may be a malfunction of the chip responsible for the video output.
What to Do? How to Fix the Problem with Screen Flickering MacBook Pro?
Software Solutions
As I noted above, the problem can be caused by both software and hardware. Therefore, first of all, it is worth checking all the settings and downloading all updates. Perhaps some software is causing the problem. This immediately becomes clear if the flickering of the screen on the MacBook occurred after installing new applications.
First of all, you should try to turn off the 'Automatically Adjust Brightness' feature witch depending on the lighting.

Secondly, resetting SMC settings can help, how to do it on newer MacBooks series is described in this article:How to Reset SMC on MacBook Air 2018 or MacBook Pro 2018?
How to do this on older MacBook models can be found in this article: How to Fix Fan Noise & Overheating of your Mac?
Hardware Solutions
Important! If it comes to the hardware part, then you should realize that without the necessary skills to work with complex computer devices, you should not do this by yourself.
If you still want to do it by yourself, then you should check the following:
First of all, it is worth checking the bused interface. In fact, bused interfaces are one of the most fragile elements of modern technology, not excluding the MacBook. Even a slight mechanical effect can cause a break in the bus or breaking contacts at the point where the loop is connected. In fact, this is a well-known and easily fixed problem that does not take much time in the service center. It is fashionable to find the location of the clip with the display cable on the network, since the design varies depending on the Mac models.
Second, and it's more difficult if the display decoder breaks down on your MacBook. Apple has not contemplated replacing the decoder on the MacBook. Therefore, in the event of a malfunction, it is required to change the entire matrix of the MacBook. It is expensive and inconvenient, but there is no other way.
Third, and it is much easier and cheaper if the fault occurs at the level of the graphics adapter. This reason is easily determined by simple tests and is also easily eliminated. It should be noted that in service centers almost no one changes individual chips on a graphic card, this is a very complex and time-consuming process. Most often, they change the entire adapter.
Accordingly, in both cases, you can safely contact the Apple service center with a display decoder and a graphics module.
Conclusion
If software solutions did not help you, then it is better not to try to solve the hardware items yourself, as mentioned above. Correction of this problem will require the help of a service center. Only they will be able to determine the real cause of the flickering of the MacBook Air or Pro screen flickering and provide expert assistance in resolving the problem.
