Black screen of death on MacBook could be associated with software issues. For this reason, we need to update all apps to their latest versions including the macOS.
However,before you update macOS,you need to make reparation as listed below:
Backup your Mac. You could use Time Machine to backup your Mac. iCloud or USB would be also choices to backup your Mac.

More solutions if your MacBook Pro won’t turn on
Force restart your Mac
Black And Light Mac Os X
In most cases forcing your Mac to restart helps to fix it if your Mac won’t boot. The variance of this issue is your Mac not waking up after sleep. Try to open and close the MacBook lid and press a few keys on a keyboard. It might help, but if it doesn’t, in no way should you panic — first, let’s perform a quick force restart.
- Hold down the Power key for about 6 seconds.
- Wait for your Mac to shut down and press the Power key again.
Reset your Mac’s NVRAM settings
NVRAM stands for non-volatile RAM and is basically a functionality that stores in-memory settings for display, speakers, primary startup disk, etc. Everything remotely connected with the boot process (like your MacBook won’t turn on) can be set back to factory settings during the NVRAM reset.

To flush NVRAM settings:
- Shut your Mac down.
- Press the Power key.
- Wait for your Mac to start loading.
- When you hear a startup sound, hold down Cmd + Option + P + R.
- Keep pressing the keys until you hear a second startup sound
Do basic Mac maintenance: disk permissions and Login Items
Did resetting NVRAM do the trick? Now that your display is back to the light, you should be able to do a bit of maintenance under the hood of your Mac. In many reported cases, removing old cache files and broken login items helped prevent the “black screen” problem. Oftentimes, the reason for your Macbook black screen problem is broken disk permissions not allowing your Mac to boot normally. A good solution is to use the app called CleanMyMac on your machine and run the Repair Disk Permissions command.
- Download the app (it’s free to download).
- Install it and go to the Maintenance module.
- Tick Repair Disk Permissions and click Run.
From my experience, it’s the easiest way to optimize hardly-accessible parts of your Mac.
Another possible culprit — the corrupted Login Items. The truth is, some apps like antivirus software would inadvertently sneak into the list of your startup programs; if something goes wrong with the app, it will then affect your Mac’s booting. So, it makes sense that you check your Login Items list and uninstall the unwanted app — both too can be done with CleanMyMac’s free version.
Zap your Mac’s SMC settings
SMC is a System Management Controller. What it controls is temperature, lights, keyboard, fans, and many other side-processes. According to Mac support forums, resetting SMC helps in 90% of the cases when your Mac’s screen goes black. To perform this trick, follow the tips below.
For a MacBook with a non-removable battery:
- Shut your Mac down.
- Connect your Mac to a power outlet.
- While your Mac is still shut, Press the Shift + Option + Control and Power key simultaneously.
- Let go of the keys and boot your Mac again.
For a Desktop Mac: iMac, iMac Pro:
- Unplug the power cable.
- Wait for about 15 seconds.
- Plug your Mac back in and leave it for about 5 seconds.
- Start your Mac in a normal fashion.
Enter your password — a surprising trick that works
Though it looks counter-intuitive, you may try this solution when your Mac screen goes black. Still, with your Mac’s black screen on startup, enter the password — as if you would normally do. Now press the Return key. Lots of users have reported that this option helped to bring their Macs to life.
A variance of this trick has been found on many Mac forums. Once again, it implies that you press the keys on your Mac in a “blind” mode, hoping that it will light up.
- Press the Power key — just once to summon the restart dialogue.
- Press the S key to send your Mac to sleep.
- Press and hold the Power key to perform a forced shut down.
- Wait for about 15 secs and start your Mac as usual.
Check for any magnets nearby
Inside your MacBook's lid, there's a tiny magnet that reacts when the lid is closed. But when there are other magnets nearby that sends a wrong signal to your MacBook telling it to shut down. For example, this happens if you place your computer atop of an audio speaker.
Placing your MacBook next to a magnet may accidentally shut it down, even if the lid is open.
MacBook asking you to reset your password on bootup?
It may happen that your Mac became unresponsive and asks you to reset your password. However, after following all the on-screen instructions and changing your password, nothing happens — you still see the black screen. Don't worry, there is an easy fix.
When the screen is black, shine the light behind the display through Apple. This will help you see the login icon and put the cursor in the correct place. Then just log in, and the screen will come back.
