So you are trying to wake your Mac from sleep and it just wouldn’t. All you see is black screen on your MacBook Pro no matter what keys you are pressing. Below you’ll find a couple of solutions (mostly based on users’ cases) to bring you Mac back to the light.
The options I’ve mentioned will help you reset your password and log into your account. However, if you still can’t get into your Mac because of a lost or forgotten password there’s a way to. For last 2 days I am not able to login to my MacBook Pro. It was working fine and suddenly for no reason after I last shutdown my mac I am not able to login. The mac starts up fine and goes to the login screen. After I enter my password the progress bar is stuck in 70%-80% and sometimes at 100%. I tried resetting NVRAM and SCM but it didn't help. When the login screen appears, select a user with administrator privileges, type the appropriate password, and then press Return. Note: If your computer is set to automatically log you in each time you start it, but you want to log in as another user, hold Shift when the Mac OS X Startup Screen appears and release it when the login screen appears.
Reasons your Mac screen goes black:
- 3rd party apps that expand the screen
- Recently upgraded operating system
- Corrupted display and energy settings
- Cables not connected
Easy fixes for Macbook black screen

1. Adjust your display’s brightness
It’s possible you had accidentally pressed the brightness keys on the keyboard so your screen dimmed down. Could it be your cat stepping on keys? Use F1 and F2 buttons to light black screen on your Mac.

Examine your charger cable is intact and if your Mac is charging. Is the green light on? To rule out the power issues, check if your Mac produces any noise — from the hard drive or fans. If you still see black screen on Mac, read on.
3. Disconnect all peripherals
Remove all external devices like printers or external drives. These devices may start their own dialogues which could interfere with your display settings.

Force restart your Mac
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 MacBook lid and press a few keys on a keyboard. It might help, but if it doesn’t in no way you should panic — first let’s perform a quick force restart.
1. Hold down the Power key for about 6 seconds.
2. Wait for your Mac to shut down and press the Power key again.
2. 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 even remotely connected with boot process (like your MacBook won’t turning 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 make 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 to 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 for this is to use the app called CleanMyMac on your machine and run Repair Disk Permissions command.
- Download the app (it’s free to download)
- Install it and go to 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. 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 System Management Controller. Kmplayer 2011. What it controls is temperature, lights, keyboard, fans, and many other side-processes. Archiver 3 0 9 x 2. 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 Shift + Option + Control and Power key at the same time.
- 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 do normally. 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 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.
MacBook asking you to reset password on bootup?
It may happen that your Mac became unresponsive and asks you to reset 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 the Apple. This will help you see the login icon and put the cursor in the correct place. Then just login and the screen will come back.
The last-ditch solution to MacBook black screen
Re-install the macOS
The lion’s share of issues we deal with on our computers are software-related. MacBook display not working is not an exception. So it makes sense that you update all your apps to their latest versions including the macOS.
Here is the guide on how to quickly re-install the macOS:
For macOS Sierra
For macOS High Sierra
For macOS Mojave
For macOS Sierra
For macOS High Sierra
For macOS Mojave
If all of the above didn’t work, let go of it and take your Mac over to the service — you’ve done all you could. We hope this article was fun and helpful — feel free to share.

A few months ago, macOS Mojave gets launched to the delight of many Mac users. It comes with an interface overhaul that needs to be initiated by the user, involving the popular Dark Mode. New features also include the Desktop Stacks, the reinvented Finder, and the new Gallery view, to name a few.
As far as issues go, however, a Mojave upgrade isn’t really immune to errors. One issue that keeps bugging a number of users is when their MacBook Pro randomly goes back to login screen. Here’s a specific case that demonstrates this problem.
A user updates his MacBook Pro to Mojave the previous day. After the installation process, he clicks on a user and tries to log in. Within just 30 seconds, the screen flickers, taking him back to the login screen.
The glitch happens for all accounts on his machine. He has tried repairing the disk as well as exhausting all other repair processes. But the error manages to persist on his laptop, which admittedly is an old one but should still work fairly well.
Let’s get to the bottom of things with this quick article.
MacBook Pro Returns to Login Screen Randomly
The difficulty here is that there appears to be no clear pattern or trigger for the misbehavior. The computer seems to return to login screen randomly and without any exact reason to do so, other than it happens following a Mojave update.
We’ve connected with our in-house experts and scraped the web for viable solutions to this post-Mojave update issue. Before performing these fixes, though, try to check everything from your hardware connections to your system’s stability via running a Mac repair tool that you trust. Sometimes, junk files that have accumulated over time can interfere with normal systems and processes, in turn ruining your Mac’s performance.
If your MacBook still randomly goes back to the login screen, try these solutions:
Making Basic Checks on Your MacBook
You can try to download iStat Pro and check on your actual RAM usage. It is recommended that you check how full your hard drive is, as you may already be using up your RAM. As a result, your hard drive may have insufficient space to create enough virtual memory.
Make sure, too, that your laptop is not overheating. This can happen while you are playing videos, gaming, or working on intensive processes for a long period of time. Rule out this reason for why your laptop is crashing and randomly returning to the login screen.
Creating a New User Profile
If it appears that the problem is occurring due to your user profile, then you might want to consider creating a new one. Log out of your existing user profile and then log back in with the new one, checking if the issue is finally resolved.
Add a user by following these steps:
- On your Mac, click Apple menu > System Preferences. Next, proceed to Users & Groups.
- Click the lock icon in order to unlock it. Enter an administrator name as well as password.
- Afterwards, click the Add button located below the list of users.
- Click the New Account pop-up menu. From here, select a type of user. An Administrator can add and manage other users, install apps, and change settings. A Standard user is set up by an administrator, while users with Managed with Parental Controls type can access only the content specified by the admin. Sharing Only users, on the other hand, can access shared files remotely, but they cannot log in to or change settings.
- Input a full name for the new user. Then, an account name is automatically generated. Use a different account name by entering it now. Note that you cannot change this later.
- Enter a password for the user. Re-enter it to verify. Enter a password hint as well.
- Hit Create User.
- Depending on the type of user you create, you can perform different steps. For an administrator, choose Allow user to administer this computer. For a managed user, choose Enable parental controls.
Performing an SMS and PRAM/NVRAM Reset
System Management Controller (SMC) is a chip embedded in Intel-based Mac devices. It is responsible for the workings of most Mac parts, including keyboard and peripherals. It also figures in the operation of your hard drive and power supply. Reset the SMC of your MacBook with these steps:
MacBooks with Apple T2 security chip:
- Shut down your laptop.
- Press and hold the Power button for some 10 seconds. Restart afterwards. If you are having trouble upon startup, switch off your machine again.
- Press and hold the Power + Shift + left Control + left Option keys for a few seconds.
- Release all the keys and wait a few more seconds.
- Reboot your MacBook.
MacBooks with non-removable battery:
- Shut down your laptop.
- Press and hold the left Option + Control +Shift keys while you press the Power button for around 10 seconds.
- Release all the keys at once and wait for a number of seconds.
- Switch on your MacBook.
MacBook released before 2015:
- Shut down your laptop.
- Remove the battery.
- Press and hold Power for 15 to 20 seconds.
- Put back the battery again.
- Switch on your MacBook.
Older Mac models have Parameter Random Access Memory (PRAM), while modern Intel-based ones have Non-Volatile Random Access Memory (NVRAM). You can reset your PRAM or NVRAM when there are software-related issues, the computer forgot specific settings, or there are connectivity problems.
Follow these instructions to reset the PRAM or NVRAM:
- Turn off your MacBook.
- Press Power.
- Before reaching the grey screen, press the R + P + Command + Option keys all at once. Hold them down until the computer restarts and you hear the startup sound.
- Release the keys together.
Using Terminal
This method comes directly from Apple support, with guidance from their engineers. Here are the steps to follow closely:
- Boot into Recovery. Do this by holding the Command + R keys down and turning on your computer.
- Open Disk Utility. Next, choose the startup volume.
- Take note of the name of the volume, which is typically Macintosh HD. If the name is dimmed, hit the Mount button. Enter the password of a user who can unlock the disk.
- Take note of the number that is shown next to Available.
- It’s time to quit Disk Utility.
- Next, choose Utilities > Terminal. Replace the bolded hard drive name with the name your drive is called. Enter this command: cd “/Volumes/Macintosh HD/Library/Audio/Plug-Ins/HAL”
- If this command gets accepted, input this on the next line: mv *.plugin .
- It the system takes the command, quit Terminal.
- Reboot your computer in normal mode and log in as usual.
Final Notes
It can be incredibly disruptive for your MacBook Pro to randomly return to the login screen following a Mojave update. Since it’s hard to figure out how long this issue will last and what is actually causing it, the solutions above are worth a try. Don’t think twice about getting help from Apple support if the issue persists!
