Mac Screen Goes Black? Here’s your troubleshooting guide!

Have you ever tried to boot your MacBook Pro and found it unresponsive? It happens to many users, and can seem like your computer is just broken. 

There are many reasons you encounter the dreaded MacBook black screen. It may be a deep issue, like a corrupted driver or display, or something as simple as a third party app hijacking your display’s settings. 

We’ll tell you why it happens, and how to fix it when your MacBook Pro screen goes black randomly.

How to fix MacBook Pro screen black

When your Mac screen keeps going black, there are several things that can cause it. Unfortunately, your Mac won’t tell you what’s going on, so you’ll have to do a bit of diagnosis. But don’t worry – it’s not hard! We’ll show you how to fix your issues with ease.

Check the power of your MacBook

Sometimes the ‘MacBook screen black’ issue is solved by a Mac not being plugged in or charged up. Pretty embarrassing when you realize it’s the issue, so always make this your first checkpoint when diagnosing the problem.

MacBooks typically display an icon when not plugged in and out of juice. iMacs and Macs not tethered to a power source simply won’t turn on. As silly as it can see, charging your device is the easiest MacBook Pro black screen fix there is.

Check screen brightness level

It’s also possible your screen brightness is just turned all the way down! Once you’re sure your Mac is powered on or charged, try using the screen brightness keys on your keyboard. If you see the screen brightness logo on the screen, you may be in luck!

Settings can be tricky to manage, which is what makes One Switch a great accompaniment for your Mac. The app lives in your menu bar, and provides one-touch access to many of your Mac’s settings like Night Shift, Do Not Disturb, Display Sleep, True Tone, and Dark Mode. It also tidies up your desktop by hiding icons with the click of a button. One Switch also offers easy, one-click pairing for Bluetooth peripherals like AirPods.

Force restart your Mac

Sometimes your Mac just needs a hard restart to fix its issues. Apps services may be bogging it down, leaving it unable to figure out how to proceed. If you’ve powered your device up and made sure the screen brightness is up, a hard restart may fix your issues. Here’s how to do it when your Mac is on:

  1. Hold down the power button for seconds
  2. When your Mac powers down, wait ten seconds
  3. Press the power button to boot it back up

If your Mac is off, hold down the power button for a few seconds to try to force it to boot up if pressing the power button once doesn’t help.

Resetting the NVRAM/PRAM

NVRAM (nonvolatile random-access memory) and PRAM (Parameter RAM) are both small memory partitions that store some settings for your Mac like volume control and display resolution, which allows it to access those settings quickly. At times, either (or both) of these RAM partitions can get ‘stuck’ – but a reset can help! Here’s how it’s done:

  1. Power your Mac down completely
  2. Press the power button to start your Mac’s bootup process
  3. Immediately hold down the option + command + P + R keys while your Mac boots
  4. Hold the keys for at least 20 seconds

Note: your Mac may appear to restart while you’re holding the keys down. Macs with a startup chime may sound a second chime during this process. For newer Macs with Apple’s secure T2 chipset, you can release the keys once the Apple logo appears for the second time during the bootup process.

Reset SMC settings

SMC (Systems Management Controller) is a feature for Macs controlling temperature, keyboard, lights for the keyboard and display, fans, and other processes. Like resetting PRAM and NVRAM, triggering the SMC is a common (and easy) fix for the MacBook black screen issue.

Here’s how to reset your SMC settings on Mac:

  1. Power your Mac down completely ()
  2. Make sure your Mac is connected to power
  3. Hold down these keys while your Mac is powered down: Shift + Option + Control + Power button
  4. Once your Mac starts booting up, release the keys

Repair Disk Permissions

Like settings that car errantly cause your Mac’s screen to go dark, so can disk permissions. On the Mac, disk permissions allow apps, files, and folders access to other settings on your Mac. It’s how apps can cause issues, and resetting permissions can be a big help.

The best app for cleaning up your entire system is also the best for resetting your disk permissions. CleanMyMac X has a section named “Maintenance” with a feature named “Repair Disk Permissions” that makes clearing up your Mac’s disk permissions a snap. Here’s how to reset your disk permissions on a Mac using CleanMyMac X:

  1. Open CleanMyMac X on your Mac
  2. Select “Maintenance” from the left side of the window
  3. Select “Repair Disk Permissions” in the main window
  4. Click “Run” at the bottom of the window

That’s all it takes! CleanMyMac X will reset your disk permissions in a snap.

repar disk permissions mac

Unplug all accessories

Like apps messing with your Mac’s settings, peripheral devices can also cause issues. Printers, external drives, keyboards, trackpads, mice – all of these things can cause your Mac to go dark on you. If all else fails, make sure your Mac is disconnected from other devices, too.

Boot into Safe Mode

Safe Mode for your Mac prevents other startup services from booting up. You likely have a few different apps or services that boot up when your Mac does, and those apps may be causing issues. Launch agents are meant to provide background support for you without the need to launch an app every time you boot up your Mac, but some can be troublesome.

To boot into Safe Mode, follow these steps:

  1. Power your Mac down completely
  2. After your Mac has sat idle for seconds, press the power button to turn it back on
  3. Immediately hold down the Shift key as your Mac boots up
  4. When you see the login window, release the Shift key and login

Note: You may be asked to login a second time. This is normal; at one or both login screens, you should see “Safe Boot” in the upper right corner of the window.

Reinstall the macOS

If all else fails, you can always try a clean install of macOS. Keep in mind this essentially starts your Mac from square one, like a brand new device. It should be your last-ditch effort.

But backing up your Mac should be a practice you do regularly, especially if you’re going to reinstall macOS. To avoid losing all of your files and folders, create a backup often so you have all of your digital stuff tucked safely away on an external drive.

For this, there’s no better app than Get Backup Pro for Mac. It performs backups quickly, and you can even automate the process so your Mac backs up automatically on a given schedule. You can set your Mac to backup to an external drive nightly, weekly, or whenever!

Get Backup Pro mac

Get Backup Pro creates full backups, or you can choose the folders you want to backup. You can also create full, bootable backups via cloning, and compress your backups to save almost 60 percent storage space!

Conclusion

The dreaded black screen of death for Macs is frightening, but there’s typically an easy fix. We’re sure one or more of the solutions in this article will solve your black screen issues.

Many issues can be solved with maintaining your Mac, which is why CleanMyMac X is so useful. It performs routine maintenance to keep your Mac running in peak condition, and has several modules for those times you want to give your Mac a more thorough scrubbing – like resetting disk permissions.

Get Backup Pro is the perfect accompaniment for your Mac’s backup regiment, too. It creates backups on your schedule, and is a lifesaver if your Mac ever encounters issues that cause you to need to boot from scratch.

MacBook Pro (Early ) Retina 13" Display Black Screen with Chime

Hi there -

The display on my Macbook Pro (Early ) Retina 13" is black when I turn it on - I hear the chime, the keyboard backlight still works, sound works. But I noticed that the backlight on the Apple logo does not turn on.

I've tried everything that was recommended by others - such as trying the PRAM reset and resetting the System Management Controller. But no luck here. I was able to log on briefly with the screen display working correctly - weirdly, it asked me to select a language and prompted me to answer why I was having trouble logging in. I didn't really pay attention to all of this as I was just eager to log on

I took it to the genius bar yesterday, but they said it could be a display issue that would need to be sent in for repair. I have a little hope in me that this can be fixed without having to spend $ - a little upsetting that I've had this for less than 2 years.

Any guidance, tips, fixes are welcome. Thank you so much in advance!

A Solution for MacBook Pro Booting to a Black Screen

MacBook Pro with a Black Screen

Rarely, a Mac may encounter some peculiar issue during system boot that can cause quite a bit of panic, like booting to a completely black screen. It would be easy to interpret that as a potential hardware problem, and in some particularly rare situations that may be the case, but it&#;s more often a software issue that can be resolved with some simple troubleshooting steps.


Case in point; one of our readers experience with his MacBook Pro, which out of the blue rebooted to a completely dark screen. Though it&#;s rare, we figured this would be a good opportunity to share three potential solutions to this problem, and similar issues, should you encounter a dark screen on system start.

First, Reset the System Management Controller to Fix the Black Display on Boot

The first thing you&#;ll want to do resolve nearly every power related issue on a Mac is to reset the SMC, or System Management Controller. This will dump and reset settings for anything power management related, and is long known to resolve problems with things like fans, heat, sleeping problems, and of course, display issues.

On any modern MacBook Pro or MacBook Air with a built-in battery, which is just a bout all of them nowadays, this is how you do that:

  1. Shut down the Mac and connect it to your MagSafe adapter and a wall outlet as usual
  2. Hold down the Shift+Control+Option+Power button at the same time for a few seconds
  3. Release all keys at the same time, then boot the Mac as usual

Older Macs can find directions here for the same process on their machines, it&#;s slightly different if you can take out the battery.

When the Mac boots, hopefully the black screen has gone away and you&#;re back to normal, but if it doesn&#;t&#; reader Nathan D. wrote in with the next tip.

Second, Try a Keypress Sequence to Ditch the Black Screen

Regular readers may recall that we covered some OS X keyboard shortcuts for the Shutdown, Sleep, and Restart controls of just about every Mac, and this little key press sequence takes advantage of those. Oddly enough, it seems to work to resolve some of the mystery Mac booting into black screen issues. Here&#;s the precise sequence to follow:

  1. Press the Power / OFF button once &#; this will bring up the dialog box which you can&#;t see
  2. Press the &#;S&#; button &#; this is the shortcut to sleep the Mac
  3. Hold down the Power button until a hard shut down is forced
  4. Wait about 15 seconds, then hit the Power button again to turn it back on

This key press solution was discovered by reader Nathan D., who found it tucked away on MacRumors Forums, and it has worked for several other commenters there as well. Some other users on the MR forums suggest that resetting PRAM helped them too, but most power issues are resolved by the SMC reset.

Try a PRAM Reset to Resolve the Black Boot Display

If the above two tricks failed, a PRAM reset can often do the trick, as many of the commenters on this article can attest to. As a potential solution to the black screen on boot, this is done upon restarting the Mac similar to an SMC reset:

  1. Reboot the Mac and as soon as you hear the boot chime, hold down the Command+Option+P+R keys together
  2. When you hear the boot sound again, the PRAM has been reset so let the Mac boot again as usual

At this point your Mac should boot again as usual and no longer have the black display, loading Mac OS or Mac OS X as usual.

Finally; Enter Password, Hit Return

Some users in our comments report an interesting alternative finding if they hit the black screen on boot; if they enter their regular login password and hit the Enter/Return key, the Mac boots up as usual and they&#;re good to go. Try this out, it might work for you:

  1. When the Mac boots into the black screen, enter the password you&#;d use to login to the Mac as usual
  2. Hit the Return key

If this works, you&#;ll know rather quickly because the black screen will give way to the regular Mac OS desktop.

Turn Off Automatic Graphics Switching (for black screens on dual-GPU MacBook Pro only)

Some MacBook Pro models have dual graphics cards that switch automatically. For whatever reason those models can sometimes boot directly to a black screen. Often this can be remedied by simply disabling automatic graphics card (GPU) switching on MacBook Pro as instructed here:

  1. From the  Apple menu choose &#;System Preferences&#; then go to &#;Energy Saver&#;
  2. Toggle the switch next to &#;Automatic Graphics Switching&#; to turn that off
  3. Disable automatic graphics switching on MacBook Pro

  4. Restart the Mac as usual

Did one of these solutions work to get past the black screen on Mac boot for you? If you happen to run into this unusual issue with your Mac, let us know how you resolved it by leaving a comment below, and if the above tips worked for resolving the boot to black screen problem on your MacBook, MacBook Pro, MacBook Air, and whichever Pro or Air model it may be. And of course if you have your own solution to the booting to a black screen issue, share that below in the comments as well!

2015 macbook screen pro black

Even if you&#;ve never been a Windows user, you should have heard the phrase &#;black screen of death&#; (BSOD) or something similar. You also may have thought Mac had nothing similar… until now.

The Macbook Pro screen goes black when fully opened users may experience is hardly a death sentence, but it is fairly annoying and ruins whatever activities you were previously engaged in.

It&#;s exactly the kind of problem that brings things grinding to a halt while being frustratingly unpredictable, so we&#;ve collected a few ways to help you fix it.

Contents

Why Did Your MacBook Pro Go Black: Possible Causes

Power Issues

It might sound kind of obvious, but power issues are the most common reason your Mac&#;s screen is blank. Whether it&#;s a bad battery or a faulty charging cord that lets you fall into the black screen trap, this is always a good place to start looking.

Waking from Sleep

Black screen issues are most common when waking your MacBook from sleep. Whether this is an issue on Apple&#;s end or the user remains unclear, but it is usually described as opening the lid of your MacBook only to have your screen refuse to wake up. Although it may seem like your computer has turned on (via the activity indicator, fans, or noises), the screen remains blank. The cause of this scenario remains unclear, but it is a well-recognized situation.

Broken Disk Permissions or Login Items

Sometimes, the cause for your Mac to go black screen or even not allow your laptop to boot up normally is due to broken disk permission issues; While other times the culprit is certain apps that sneak into the auto startup list and affect your MacBook&#;s booting. If that&#;s the case, you&#;ll have to check those problems and fix them (see Step 5 for more).

Software/App Error

Everybody wants to blame things on a glitch. It&#;s a simple answer to a seemingly otherwise unsolvable problem, especially if you&#;re booting to a black screen or something equally infuriating. Some known bugs could be causing the issue, however, so this is a valid possible cause. Make sure to check official Apple channels such as the security update list or Apple Community Forum to find out if this is your case.

How to Fix Unresponsive Black Screen

In this section, we&#;ll take it from the top and show you how to change an unresponsive black screen back to normal.

Step 1: Check Your Power

If your MacBook Pro was previously charging, make sure the plug wasn&#;t suddenly yanked out of the wall or that anyone tripped over the cord. You should also check your battery cycles to see if it needs to be replaced.

To do this, go to the Apple menu from the top left of your Mac and select &#;About this Mac&#;, then &#;System Report&#;. Once the report opens, pick &#;Power&#; from the right-hand side.

From the power panel, look down until you find the cycle count and condition for your battery. If it says &#;Poor&#; or &#;Bad&#;, it&#;s time to consider purchasing a new battery for your MacBook Pro.

If you can&#;t buy a battery right now or need a solution in the meantime, keeping your MacBook plugged in should provide temporary relief. While it does reduce the working capacity of having a laptop, it&#;s only a temporary solution.

Step 2: Restarting

If it&#;s not the battery (or if you can&#;t access the system report at the moment to check), your next best solution is restarting the machine. You can do this in a couple of different ways:

  1. Use the CNTRL + EJECT keys to bring up the dialog box, then press ENTER even if you can&#;t see the dialog box since &#;Shut Down&#; is automatically selected. Then press the power button again once the computer has finished shutting down to restart it.
  2. CNTRL + CMND + EJECT will automatically trigger a restart.
  3. Hold the power button for 5 seconds to have it shut down. Wait 15 seconds and press it once again to reboot.

Your MacBook should restart to its normal state, resolving the black screen issue.

Didn&#;t work? Move onto the next step listed here for a special key pattern that might do the trick.

Step 3: Try a Known Key Sequence

Some users have reported that a specific key sequence dug from the depths of the MacRumors forum has helped resolve their black screen booting issues, so it&#;s worth a shot trying. This is what you have to do:

  1. Press the power button once, which normally brings up a shutdown dialog box (you won&#;t be able to see it with a black screen).
  2. Press &#;S&#;, the hotkey for sending your Mac to sleep.
  3. Hold the power button to force a hard shut down.
  4. Wait around 15 seconds before pressing the power again to restart.

And voila, your MacBook should boot as normal instead of to a black screen.

Step 4: Resetting the NVRAM/PRAM

Or… not. If you&#;re still having problems even after trying multiple methods or the problem is re-occurring it might be time to take a bit more drastic measures. You&#;ll be resetting the NVRAM/PRAM on your Mac — here&#;s how to do it.

  1. Shut down your Mac (see above if you aren&#;t sure how).
  2. Press the power button. Once you hear the startup chime, hold down CMND + OPT + P + R.
  3. Hold these until you hear another startup chime, then release them.

Your Mac should boot normally now, although you may have lost some setting along the way so make sure to check system preferences to see if your display, date/time, and disk options are all in order.

Step 5: Reset the System Management Controller

An SMC reset is another thing you can do to fix a black screen. This is a good thing to know how to do because it can resolve several other issues you might experience with your MacBook, such as overheating slowdowns. 

To reset the SMC on your MacBook, follow these steps: 

  1. Shut down the computer
  2. Connect to the power source
  3. With the MacBook powered down, hold down Shift, Control, Option, Power at the same time for about 10 seconds
  4. Release the keys
  5. Restart the computer
  6. The SMC should now be reset

The SMC reset can vary from this if you have an older MacBook; check out here for more. 

Step 6: Boot into Safe Mode

You might be experiencing a black screen for several reasons, and one of them might be issues with your startup disk.

You can fix this problem by booting your MacBook into safe mode and allowing it to run a check on the disk. 

To boot in safe mode, follow these steps:

  1. Turn of your computer
  2. Hold down the Shift key while powering back up until you see the Apple logo
  3. Let go of the key after the logo appears

The computer will now start up into safe mode and might take a little longer than you expect as it runs diagnostics on your startup disk.

Once it boots up completely, you can restart again to enter into a normal startup and see if the black screen issue is resolved. 

Step 7: Check & Repair Disk Permissions

Like I said, one of the causes for black screen is due to broken disk permissions. Fortunately, it&#;s easy to diagnose and fix.

All you need is run CleanMyMac on your Mac. Open the app, go to Maintenance > Repair Disk Permissions, click &#;Run&#; and you&#;re all set.

Step 8: Check for App Issues or Bugs

Again, the best way to identify those suspicious apps is to run CleanMyMac.

In the Extensions section, check Launch Agents and Login Items. If you find some apps that launch automatically (often without your consent), feel free to disable or remove them.

Another way to do this is by searching the Apple Community for a post that most matches yours to see if any bugs (and ways to squash them) have been identified, although you can also make your post.

Other forums such as MacRumors and iFixit are also great places to start, as well as searching for general articles.

For example, Mark Gibbs from NetworkWorld discovered that using his iCloud password caused the computer to experience an error where it booted to a black screen with just his mouse and no login options.

It&#;s a strange correlation, but sometimes very random things can send your computer into a frenzy, so it doesn&#;t hurt to look.

Final Words

Black screens are never fun to deal with. Besides the unending frustration, rebooting and potentially losing your work aren&#;t exactly enjoyable activities. Hopefully, this guide has helped you alleviate the issue and sets you back on your feet.

MacBook Pro Black Screen of Death - Fixed 2019 (Working Method)

Updated instructions to fix macbook pro with black screen¶

Tags: python, apple

Last week I wrote about my macbook pro and its screen that suddenly stayed black after waking it from sleep. Including instructions on how to fix it. I now have improved instructions…

The piece of crap did it again. (This time there was no external monitor in play, btw)

Symptoms: you open up your late macbook pro 15” and expect it to wake from sleep in seconds. Instead the screen stays black.

  • Press shift-option-control-power and release them all at the same time. This resets the “system management controller”, amongst others it makes sure the “power” button actually reacts.

  • Now look at the back of your mac’s screen. Make sure the light of the apple logo is off. If necessary, keep the power button pressed for 5 seconds to force a shutdown. (The power button should work again after step 1).

  • Keep your fingers ready for pressing command-option-p-r at the same time. You need both hands for this weird combination. Press the power button and then hold these four keys. Your mac will now actually boot, give you the startup sound and lo and behold, you’ve got your screen back.

I do hope apple will fix this Real Soon. I suspect a software bug. I hope it isn’t a hardware one. It was a hardware bug (wrong solder being used for the video card connection) that brought down my previous macbook after four years… Apples are great machines for programming (python) and I’m in love with the retina display, but…

Now discussing:

Question: Q: PERMANENT BLACK screen on my MacBook AIR

My Macbook Air, my newer one, (I am using my old one now, to post this) has a black screen, unchangeably black. I have tried the things that don't require being able to see anything on a screen, like trying to reboot ( Shift+Control+Option+Power button at the same time for a few seconds, then Release all keys at the same time, then boot the Mac as usual),

which seems to be the same thing if one wants to reset the SMC (system Management Controller). Now, in addition to the screen continuing to be black, now, also, the bottom half of the laptop (ie, the side where the keyboard is) seems to be vibrating at a very high speed!

Also, I have tried:

Once I hear the chime, even though I don't know if I have turned the thing off, or if has been turned on, I type in my password as if I were actually looking at a normal screen. Doesn't have any affect.

Since I have a black screen, I certainly cannot boot in safe mode, as, I cannot click on anything, or type anything at the right time, I have nothing on the screen. Nor can I offer my serial number, or any current info about the hardware or the software, as, I cannot read anything on the screen.

The last successful thing I was doing on that Macbook Air, I believe I was just looking at things on the internet, and at one point/moment, I realized everything had frozen, so I pushed on the power button until the Air shut down. I did not do anything more for a couple of hours, as, I was wasting time anyway. When I tried to turn on the AIR again, I opened it up, and waited for the screen to show the login window. I only had a black screen, no matter what I tried, for over an hour.

So then I switched to my old computer and started the research.

Nothing seems to improve the situation. I seem to be going in circles.

I cannot get help from apple genius without proof of the serial number.

After doing all of the above, with no success, nor even any progress,

I am hoping someone out there will read this and help me out.

Thanks!! Feb. 27, around 8PM Atlantic Time.
