How to Fix MacBook Screen Black

In total, we'll introduce 8 methods below to fix the macOS Sonoma black screen. Keep reading!

Check Your MacBook's Power

MacBook Won't turn on if there is no enough power for it to wake up, boot, or work. If your MacBook Air/Pro is running out of power, it will show nothing but a black screen.

So check your MacBook's power first, and then plug in/out the charger cable to see whether it's the charger that caused this issue.

Tip
To resolve power-related issues, reset SMC is of great help.

Restart Mac

MacBook's black screen may also be caused by occasional system error, or update bugs, which may be easily fixed with a simple restart.

Press the Power button to force restart your Mac if regular restart doesn't work.

Disconnect Any Peripherals

The peripherals can sometimes affect your MacBook display effect. Especially if you are using an external display. The M1 Mac is reported of black screen more often with an external monitor. To fix this, try not to use an external monitor.

Disconnect any peripherals and see whether your MacBook is back to normal.

Reset PRAM or NVRAM

Resetting PRAM helps fix the settings stored in NVRAM that don't work as usual on an Intel-based Mac.

Here is how to reset PRAM for an Intel-based Mac:

  1. Shut down your Mac.
  2. Turn on your Mac>press and hold Option+Command+P+R immediately.
    Reset NVRAM Keys
  3. Release the keys after about 20 seconds.
  4. Adjust any system settings that were reset if asked or needed.

Run First Aid

Broken disk permission is also responsible for a black screen MacBook. To repair the startup disk, you can run First Aid from macOS Recovery. Before performing the first aid, back up your important data first.

Here is how to run first aid from recovery:

  1. Boot your Mac from macOS Recovery.
  2. Click Disk Utility once you see options in macOS Recovery>click Continue.
  3. Click the View icon>Show All Devices.
  4. Select the disk you want to repair>select the last volume on the disk to repair.
  5. Click First Aid and follow the on-screen instruction.

Boot Up in Safe Mode

Booting up your Mac in safe mode helps you rule out whether it's the startup items that lead to the MacBook's black screen.

Also, it eliminates the app's interference to the minimum.

Have a Try at the MacBook Pro Key Sequence

There is another method that is worth a try. Many users report that the MacBook key sequence did help in getting out of the MacBook's black screen.

Here is how:

press the Power button once>press S-the sleep hotkey, and then hold the Power button to perform a hard shutdown> wait 15 seconds and press the button to restart.
