How to Fix ‘Mac Booting With Black Screen’ Issue – Guide
Trying to wake up your Mac from sleep but failed? A black screen on your MacBook Pro is all you see, no matter what keys you’re pressing. Below you will find some explanations (mainly based on user cases) to bring your Mac back to light. Reasons why your Mac screen goes black:
Fix black MacBook Pro startup screen
To fix your MacBook Pro startup black screen problem, you’ll start with simple solutions to complex technical solutions Note: These solutions also apply to MacBook Air.
Solution #1: Make sure the power is turned on
Is your power on? Is power being transferred from the socket to your Mac? Make sure the charger cable is intact and your Mac is charging. Is the green light on? To rule out any power issues, listen carefully if your Mac makes any noise—from the hard drive or the fans. If your Mac was turned off due to power, try charging it for at least ten minutes before trying to turn it on again. If you still see the black screen on your Mac, something else could be the problem.
Solution 2: Disconnect all peripherals
The only accessories that should be connected to your Mac when you try to solve your Mac’s black screen issue are the charging cable and adapter. Disconnect all accessories and devices connected to the Mac. Remove all external devices such as printers, flash drives, phones, and other external drives. These peripherals can launch their own dialogs, which can interfere with your Mac’s display settings. If that doesn’t solve the problem, something else could be the problem.
Solution #3: Adjust the screen brightness
It is possible that you have inadvertently pressed the keyboard brightness keys to make the screen go dark. Or it could have been your cat. Use F1 and F2 buttons to light up your Mac’s black screen.
Solution #4: Force your MacBook Pro to restart
You can force the Mac to restart to resolve the issue. If you’ve established that the Mac startup black screen issue is on the screen, hard reset of the device may be a solution. (if you are unsure, skip this process). Forcing a Mac to restart can fix bugs and errors. See how:
Solution #5: Reset your Mac’s NVRAM settings
NVRAM stands for non-volatile RAM. This is a feature that stores settings in memory for hard drives, speakers, screen display, main boot disk, etc. Resetting NVRAM can effectively restore to factory settings (default) everything connected with the boot process, including those connected remotely. To reset Mac NVRAM settings:
Solution #6: Reboot the system management controller
Resetting the SMC will discard and reset the settings for anything related to power management. It solves amongst other issues with things like heat, sleep issues, fans and of course black screen display issues on Mac. To reset SMC on MacBook Pro or MacBook Air (with non-removable battery): Hopefully, when the Mac starts up, the Mac’s black screen will be gone and you’ll be back to normal.
Solution # 7: key sequence (keyboard)
If your Mac starts up, the black screen may disappear and your MacBook Pro or MacBook Air may return to normal; however, if it doesn’t boot, try a keystroke sequence to eliminate the black screen. If your Mac is turning on but the screen is still black, try the key sequence: This process is unusual, but it has worked for many.
Solution #8: Reset PRAM
If the above two tricks failed (solution #6 and solution #7), a PRAM reset can often be the solution to the MacBook Pro’s reset screen. Mac PRAM is memory that contains some settings for your Mac. The settings in PRAM continue even if you shut down or restart your Mac. If they get corrupted in any way, it can cause problems like black screen on Mac. This is why resetting PRAM is a potential solution to the black screen at startup. Resetting the PRAM is almost similar to resetting the SMC. To reset the PRAM:
Solution #9: Boot into Safe Mode
Sometimes the black screen on Mac is the result of corrupt information on the startup disk. A simple solution to this is to force your Mac to run diagnostics on the disk by booting it into safe mode. To start-up in safe mode: after you finish starting up, restart again to get out of safe mode and start normally to see if the Mac black screen issue is fixed.
Solution #10: Enter the password and press Return
This is an amazing alternative that works when the Mac black screen startup issue persists. All you have to do is enter your normal login password as usual and press the Enter / Return key, the Mac boots up as usual and you’re good to go. Try it, it might work for you:
Solution #11: Turn off automatic graphics switching
This solution only works for black screens on MacBook Pro with two GPUs. Some MacBook Pro models have dual graphics cards that switch automatically. Sometimes these models can boot directly to a black screen. Often, to solve this problem, you simply disable automatic graphics card (GPU) switching on your MacBook Pro:
Solution #12: Reinstall macOS
This is the last resort. If all these solutions don’t work, there could be a bigger problem than simple hardware and software solutions. Reinstalling macOS can solve the problem once and for all. You can decide to install the same MacOS product or purchase a new MacOS and install it on your Mac.
