Firing up your MacBook Pro only to be greeted by unsightly black lines across the bottom of the screen can really throw a wrench in your day, particularly when your device is relatively new and damage-free.
It's a very annoying problem, but before you rush off to an Apple service center, there are a few troubleshooting techniques you might want to explore.
These steps could potentially save you a trip and get your MacBook Pro back to its pristine condition.
So, let's get into what's causing this, and most importantly, how to fix it.
1. Restart Your MacBook Pro
Before you start worrying about heavy-duty repairs or considering a visit to the Apple Store, there's one simple trick that might just solve your problem: restarting your MacBook Pro.
Yes, it sounds too good to be true, but sometimes, the simplest solutions are the most effective.
Over time, minor software glitches can accumulate, causing various display issues, including those pesky black lines.
By performing a restart, you're essentially giving your MacBook a fresh start, clearing out any temporary glitches that might be affecting its performance.
Why a Restart Can Be Surprisingly Effective
Flushes RAM
First up, every time you restart your MacBook, it's like giving your system's RAM (Random Access Memory) a fresh start.
Think of RAM as your MacBook's short-term memory where it keeps stuff it's currently working on.
Over time, this memory can get cluttered with all sorts of temporary files and data junk, which might be the culprits behind those black lines on your screen.
A reboot clears out that digital clutter, potentially smoothing over any software conflicts messing with your display.
Resets Hardware
But it's not just about the software. A restart also gives the hardware a chance to reset itself.
Yep, even the physical components of your MacBook, including the display, get a fresh start.
This can be super helpful if there’s a minor miscommunication between your MacBook's brain (the software) and its body (the hardware) that’s causing those black screen lines.
Software Refresh
Last but not least, rebooting ensures that all those system processes that quietly run in the background get to start from scratch too.
Sometimes, one of these background processes decides to throw a tantrum, affecting your screen in the process.
Restarting your MacBook is like saying, "Hey, let's all calm down and try this again," which could be all it takes to get rid of those screen issues.

3. Reset Your SMC (Only for Intel-based MacBook Pros)
Let's talk about resetting your System Management Controller, or SMC for short.
This is a step that could potentially solve your problem with black lines at the bottom of your MacBook Pro screen.
Note: When restarting Apple Silicon MacBook Pros, the SMC will reset automatically.
Not sure if you've got an Apple Silicon MacBook Pro? Check out Apple's guide to find out if that's what you've got.
What Is SMC?
First things first, let's break down what the SMC actually does.
The System Management Controller is a chip in your MacBook Pro that controls all sorts of physical parts of the machine, including the cooling fan, battery management, and yes, even some aspects of the display functionality.
It's like the behind-the-scenes maestro making sure everything runs smoothly.
Why Reset the SMC?
You might be wondering, "Why would resetting the SMC affect the display?"
Well, although black lines on the screen can often be a sign of hardware issues like a faulty display cable or a damaged LCD panel, they can also be the result of less obvious software or firmware conflicts that the SMC manages.
For example, if your MacBook Pro is overheating due to mismanagement of the cooling system, this can lead to graphical glitches such as those black lines.
Resetting the SMC can help by restoring default settings and potentially resolving any miscommunications causing the issue.
How to Reset the SMC on MacBook Pro
Resetting the SMC is a bit different depending on whether your MacBook Pro has a removable battery, a non-removable battery, or if it's a model with the Apple T2 Security Chip.
Most newer models will fall into the latter two categories.
If you're uncertain about whether you have a T2 Chip, feel free to check here.
For Macs with the Apple T2 Security Chip:
Power Down
Ensure your Mac is completely turned off.
Key Combination for Reset
On the built-in keyboard, press and hold the Control key (left side), Option (Alt key - left side), and Shift key (right side).
This might cause your Mac to begin starting up.
Introduce the Power Button
Continue holding those three keys for 7 seconds, then press and hold the power button as well.

If previous solutions haven't worked, it might be time to dive a little deeper into your MacBook's toolbox.
Let's talk about resetting NVRAM/PRAM.
What is NVRAM/PRAM?
Before we get into the how-to, let's quickly cover what we're actually talking about.
NVRAM (non-volatile random-access memory) and PRAM (Parameter RAM) are small amounts of memory that your Mac uses to store certain settings in a location that macOS can access quickly.
These settings include things like your screen resolution, time zone, volume settings, and more importantly for our purposes, some display settings that could be causing those black lines.
Why Reset NVRAM/PRAM?
Resetting your NVRAM or PRAM (the terms are often used interchangeably, but they're essentially the same thing on modern Macs) can resolve issues because it clears out all these settings and forces your MacBook to recreate them from scratch.
Think of it as giving your Mac's memory a fresh start, which can sometimes iron out display glitches that cause black lines to appear.
How to Reset Your NVRAM/PRAM
Resetting your MacBook Pro's NVRAM/PRAM is surprisingly simple and doesn't require any tools or external software.
Here's a step-by-step guide:
Shut down your MacBook Pro
Make sure it's completely powered off, not just asleep.
Power it on and immediately press and hold these four keys together
Option, Command, P, and R.
You need to get these keys pressed before the gray screen appears; timing is key here.
Hold these keys for about 20 seconds
During this time, your MacBook may appear to restart.
You can release the keys after the second startup sound or after the Apple logo appears and disappears for the second time.
Let your MacBook Pro boot up normally
Once it's restarted, you'll need to adjust any settings that were reset, like your screen resolution, time zone, and volume levels.
5. Disable Automatic Graphics Switching on MacBook Pro
Now, if you're still experiencing graphics issues try this little trick known as disabling Automatic Graphics Switching.
What Is Automatic Graphics Switching?
First, let's talk about what Automatic Graphics Switching is. Your MacBook Pro is pretty smart.
It's designed to switch between two graphics processors – one that's high performance and another that's more energy-efficient.
The idea here is to give you the best balance between performance and battery life.
But sometimes, this switching can cause graphics issues, including those annoying black lines on your screen.
Why Disable It?
Disabling Automatic Graphics Switching forces your MacBook to use the high-performance graphics processor all the time.
While this might consume more battery, it often resolves complex graphics issues and could be the solution to getting rid of screen glitches.
If you're often plugged in or you prioritize performance over battery life, this is definitely something to consider.
How to Disable Automatic Graphics Switching
Alright, let's walk through the steps to turn off this feature and potentially solve your display woes:
Open System Preferences
Click on the Apple menu at the top left corner of your screen and select "System Preferences."
This is your control center for adjusting anything and everything on your Mac.
Navigate to Battery Settings
Depending on your macOS version, you'll either look for "Energy Saver" (macOS Catalina 10.15 and earlier) or directly for "Battery" in the System Preferences window.
The naming has evolved, but the functionality remains the same.
Find the Option
Once you're in the Battery or Energy Saver settings, look for an option labeled "Automatic graphics switching" or something along those lines.
The exact wording can vary slightly depending on your macOS version, but you're looking for the setting that controls the switching between graphics processors.
Disable It
Simply uncheck the box next to "Automatic graphics switching" to disable it.
This action tells your MacBook Pro to stick with the high-performance graphics processor at all times.
Restart Your MacBook Pro
As with most settings changes, it's a good idea to restart your device to ensure the changes take full effect.
Additional Information on Graphics Switching
External Display Connection
When you hook up an external display to your Mac, it automatically switches to using the high-performance graphics processor until you unplug the display.
This happens because the high-performance GPU is better at handling the extra demands of running multiple screens at once.
Graphics Settings Unchangeable
If you're not finding the automatic graphics switching option in your settings, it likely means your computer runs on just one graphics system.
This suggests your Mac can't toggle between a low-power integrated graphics processor and a high-performance one, as it's equipped with only one of these.
6. Check Your Cables / External Monitor
Those black lines still appear? Let's break down the steps you should take to ensure that your cables and external monitors aren't contributing to the issue.
Step 1: Check Your Cables
First of all, let's talk about cables. It might seem like a no-brainer, but the simplest solutions are often overlooked.
If you're using an external display with your MacBook Pro, a faulty or loosely connected cable could be the culprit behind those pesky black lines. So, what do you do?
Inspect the Cable
Take a close look at the entire length of your cable for any signs of wear and tear.
Bends, frays, or cuts in the cable can affect its performance.
Ensure a Secure Connection
Make sure both ends of the cable are securely plugged in.
A loose connection can lead to signal loss or interference, which might manifest as graphical glitches on your screen.
Try a Different Cable
If possible, swap out the current cable with another one.
This is a quick way to rule out whether the cable itself is defective.
Step 2: Connecting to an External Monitor
Now, if checking the cables didn't clear up the issue, the next step is to see how your MacBook Pro behaves when connected to an external monitor.
This step is crucial because it helps isolate the problem – is it your MacBook's display that's at fault, or is it something else?
Connect to an External Display
Hook up your MacBook Pro to another monitor.
This doesn't have to be anything fancy; any external screen that allows you to mirror or extend your MacBook's display will do the job.
Check for Lines
Once connected, keep an eye out for those black lines.
Do they appear on the external display as well, or are they absent?
This step is telling for a couple of reasons:
If the black lines appear on the external monitor, the issue might not be with your MacBook's display but rather with its graphics hardware or software settings.
If the black lines don't appear on the external monitor, it's likely that your MacBook's built-in display is the source of the problem.
7. Update Your macOS
Alright, we've explored a range of fixes, but there's one important step that shouldn't be overlooked – updating macOS.
Let's get into why this could be your golden ticket to a clear, line-free display.
