Basic Troubleshooting for Black Screen on Mac
Why You Can Trust MacBook Journal We always conduct first-hand research and verify every method or solution we present, ensuring you receive reliable and effective advice. Learn more about our process.
Before diving into more advanced methods, address some rookie mistakes that might be causing the issue. Here are some common mistakes to avoid and steps to take to fix the black screen issue on a Mac:
1. Check the Power Source and Display Connections
Always check for hardware issues like power source and display connections before moving to any advanced method. Perform the following checks:
- 🔋 Power Check: Make sure your Mac is on. Look for the power light. If it’s off, press the Power button to turn it on. Then, see if the screen looks okay.
- 🔌 Charge if Needed: If your Mac’s battery might be dead, plug it in. Wait 5 minutes, then turn it on and see if the screen shows up.
- 🎛️ Check Connections: Look at your Mac’s screen settings and ports. If anything is plugged in, like an external monitor, unplug it. This might fix the screen issue.
2. Increase the Brightness to Maximum
Sometimes, if your screen looks black, it might just be that the brightness is too low. To increase the brightness, find the brightness controls on your keyboard.
You’ll find two keys, one with a smaller sun and one with a bigger sun. On older MacBooks, these are F5 and F6 keys. On newer ones with a Touch Bar, they’re near the Esc key. On my MacBook Air M1 (2020), the brightness keys are F1 and F2.
Press the key with the bigger sun to turn up your screen’s brightness to 100%.
Pressing the smaller sun button will decrease the brightness, eventually dimming the screen to 0%.
3. Let the CPU Cool Down
Overheating can cause various issues, including a black screen. If your Mac’s CPU is overheating, shut it down and let it cool down for about 20 minutes. Once it cools down, restart it to see if the black screen issue persists.
Also, make sure nothing’s blocking the cooling vents. Place your Mac on a flat surface for good airflow. If your Mac gets hot often, a cooling pad can help keep it cool.
4. Check Surroundings for Magnets
Older laptops had latches to close the lid and put them to sleep. But Apple uses magnets in newer MacBooks. So, magnets near your MacBook can trick it into thinking the lid is closed, turning the screen black.
Look for magnets near your Mac, like in speakers, hard drives, or other electronics. If you find any, move them away from your Mac. This might fix the black screen issue.
5. Force Restart Your MacBook
Sudden shutdown or abruptly powering up your macOS often causes errors, glitches, or bugs in the booting sequence, causing a black screen at the startup. To fix this issue, force restart your MacBook with these steps:
- Locate the Power button on your Mac. It is often on the top-right corner of your keyboard.
- Press and hold the Power button.
- After approximately 10 seconds, release the Power button.
- Now, turn on your Mac by pressing the Power button again.
12 Advanced Fixes for MacBook Black Screen Issue
If you have tried the above steps and the black screen issue persists, there may be other underlying causes, like software conflicts or hardware problems. Below, I’ve shared some advanced troubleshooting steps for a black screen issue on a Mac.
1. Reset the System Management Controller (SMC)
When the SMC encounters a glitch or corruption, it may lead to problems like the black screen issue. Resetting the SMC restarts the hardware settings related to these functions and restores them to their default state.
This method is not applicable on Macs with M1 or M2 chips, as they automatically perform an SMC reset on every shutdown and restart.
- Press and hold these keys for at least 10 seconds: Shift ⇧ + Control ⌘ + Option + Power button.
- Release the keys and press the Power button to turn on your MacBook.
2. Boot Into Safe Mode
Safe Mode starts your Mac in a basic state with a minimum number of necessary kernel extensions. It automatically checks and repairs directory issues on the startup disk, which might resolve the black screen issue.
To boot your Mac into Safe Mode, follow these steps:
- Restart your Macbook and immediately press the Shift ⇧ key.
- Keep holding the Shift ⇧ key until you see the login window.
- Log in to your device.
- Wait for the system to complete its booting sequence. You will see Safe Boot in the menu bar.
- Restart your MacBook again to exit Safe Mode.
3. Reset NVRAM or PRAM
When the NVRAM becomes corrupt or contains incorrect settings, it can lead to various issues, including the black screen problem on Mac. Resetting the NVRAM restores these system settings to their default values, resolving inconsistencies contributing to the black screen issue.
Follow these steps to reset the NVRAM on your Mac:
- Turn off your Mac.
- After a few seconds, power up your MacBook.
- Immediately press and hold the Command ⌘ + Option ⌥ + P + R keys.
- Keep holding the keys until you hear the startup sound twice.
- Release the keys, and your MacBook will restart.
Here’s a quick tip from online forums: If the black screen persists after an NVRAM reset, give the steps another go. Many users have reported attempting this method at least twice, with some even trying up to six times.
4. Update the macOS
macOS updates include patches for known issues, compatibility improvements, security enhancements, and performance optimizations. By updating the macOS, you can ensure your system is running the latest software, which might resolve any underlying issues causing the black screen problem.
Here’s how you can check for updates and update macOS on your Mac:
- Head to the Apple icon and select System Settings.
- Select General and click the Software Update option.
- Install the updates, if any are available, by clicking the Update Now button.
- Once the update is installed, restart your device.
5. Disable Lock Screen Settings
Sometimes the black screen issue occurs due to incorrectly configured Lock Screen settings. To check and adjust these settings, follow these steps:
- Go to the Apple menu and select System Settings.
- Click Lock Screen in the left sidebar.
- Make sure the Turn display off on battery when inactive and Turn display off on power adapter when inactive options are set to a reasonable time. Alternatively, select Never to disable them temporarily.
- Restart your Mac and see if the black screen problem persists.
6. Run Apple Diagnostics
When it comes to running Apple Diagnostics, the instructions may differ depending on whether your Mac is powered by Intel or Apple Silicon. Below, I’ve shared the steps to run Apple Diagnostics on Macs with the Silicon chip and Intel processor.
If you’re unsure about your Mac’s processor, check Apple’s website to find out.
On Apple Silicon Mac
- Disconnect all peripheral devices except the keyboard, mouse, Ethernet, display, and power cable.
- Shut down your Mac.
- Power on your Mac and hold the Power button until the startup options screen with the Options icon appears.
- Press the Command ⌘ + D keys.
On Intel-Based Mac
- Disconnect all external devices except the keyboard, mouse, Ethernet, display, and power cable.

- Press the Power button and immediately press and hold the D key until a list of languages appears.
- Select a language, and Apple Diagnostics will start automatically.
- Once the checking process is completed, you’ll see a report listing detected issues. If you see an error message or reference code, note it and contact Apple Support or an authorized Apple service provider for further assistance.
Check out this list of all possible error codes you can see after running an Apple Diagnostics test.
- To finish the test, click Restart or Shut Down.
7. Use a Keypress Sequence
If your black screen issue still persists, I have another potential fix you can try that I found while researching on different forums. This fix is not found in Apple’s guides but is often successful, according to many users. Here’s how to go about it:
- Press the Power button once. This brings up a dialog box you can’t see on the black screen.
- Press the S key. This is the shortcut for putting your Mac to sleep.
- Hold down the Power button for four seconds. This will force your Mac to shut down completely.
- Wait about 15 seconds, then press the Power button again to turn your Mac back on.
8. Create a New User Account on the Mac
Some apps or settings in your user account may conflict with macOS, leading to the black screen problem. This issue can also occur due to a corrupted preference file or a problematic startup item. When you create a new user account, it starts with default settings, which can identify the culprit.
To create a new user account on a Mac, you can follow these steps:
- Head to the Apple icon and select System Settings.
- Click Users & Groups and tap the Add User button.
- Enter your administrator’s name and password and tap Unlock.
- Enter the required information, including the user’s name, account name, and password, and click Create User.
- After creating the new user account, log out of your current account and log in to the newly created account. Check if the black screen issue persists.
9. Repair Disk Permissions
Repairing disk permissions on a Mac ensures the files and folders on your system have the correct permissions, resolving issues related to software installation, accessibility, and system performance. However, this process was more relevant for older versions of macOS, particularly those before macOS El Capitan (10.11). In newer versions, macOS automatically repairs file permissions during software updates and installations, making manual repair less necessary.
If you’re using an older version of macOS (pre-El Capitan) or if you still want to perform this task on a newer version for troubleshooting purposes, here’s how to do it:
For macOS Yosemite (10.10) and Earlier
- Go to Applications > Utilities > Disk Utility.
- Choose your startup disk (usually named Macintosh HD) from the list on the left.
- Click the First Aid tab.
- Click Repair Disk Permissions.
This process might take some time, depending on the size of your disk and the number of files.
For macOS El Capitan (10.11) and Later
In these versions, you can’t repair disk permissions from Disk Utility due to System Integrity Protection (SIP). However, if you still want to try, you can do it through the command line. Always backup your data before performing system operations like this.
Here’s how to go about it:
- Go to Applications > Utilities > Terminal.
- Type the following command and press Enter:
sudo /usr/libexec/repair_packages --verify --standard-pkgs /
- Then type the following and press Enter:
sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /
This will run a permissions check and repair.
On newer Macs, SIP may prevent certain system modifications. If a command doesn’t work, it might be due to SIP.
10. Reinstall macOS
Reinstalling macOS may resolve the black screen issue with its fresh files. However, this solution will erase all data on your device. So, back up your Mac data before attempting this solution.
Here’s how to reinstall macOS on your Mac:
- Restart your device, and hold down Command ⌘ + R until it boots up.
- Select Reinstall macOS from the list of options and click Continue.
- Follow the prompts to complete the reinstallation process.

11. Use Target Disk Mode
Target Disk Mode on a Mac usually isn’t a direct fix for black screen issues. It’s mainly for data transfer and troubleshooting, not display problems. But, if a software or OS glitch is causing your Mac’s black screen, Target Disk Mode can help. It lets another Mac access your troubled Mac’s hard drive to diagnose and possibly fix the issue.
Here’s how you can use Target Disk Mode on Mac:
- Start by shutting down the Mac with the black screen issue.
- Connect the two Macs using your FireWire or Thunderbolt cable.
- Turn on the problematic Mac and immediately hold down the T key.
- Keep holding it until you see the FireWire or Thunderbolt icon displayed on the screen. It means the Mac is ready to use as an external drive.
- On the other Mac, you should see the external drive appear as an available disk in the Finder.
- You can access the files and data on the troubled Mac’s hard drive from the functional Mac and perform troubleshooting steps, like scanning for malware, repairing disk permissions, or reinstalling the operating system.
12. Seek Professional Help
If none of the solutions listed above work to fix the black screen issue on a Mac, it may be time to seek professional help. You can contact Apple Support or take your Mac to an Apple Store to get it checked by a professional.
