Last update: How to change Premium subscription. I have full internet connection, but it says I'm o Then, I tried again; this time making sure to unplug at first, then plugging it back in before turning it on. Then I made sure to press all the keys at the same time and it worked :. It has been 1 month or 2 that I have this problem regularly. Today, none of these solutions worked…. What worked: press CMD-S when your mac is booting. You will see code appear yeah, the screen is still alive!
It will restart your computer and hopefully bring your screen back to life. This came about from trying to troubleshoot a FileVault password issue where the keyboard and mouse became unresponsive on boot up while asking for a password. It was here the user held down the power button which caused the black screen problem.
So what I did is first shift, control, option and power then when I pressed the power button immediately did the third step before the usual sound and it worked. Thank you to whoever is credited on this. None of the options worked for me, any advice on what to do, i go so many files and documents i want to access from my mac book pro. MacBook Pro 17, Black screen on recovery from hibernate mode and from restart after being turned off. Mahdi you saved my life! I know that sounds a little dramatic. Tried all these options and nothing worked! Turns out somehow the display brightness was just all the way down which keeps the display off!
I was scared there!!! Pram reset worked!! Thanks to the article writer and everyone on this thread!!! The first option worked for me! I rescheduled for another, in the meantime I decided to google the problem. This website was the first option! I am so excited to see my computer come back to life. Saved me money and time! Third method worked but it took me times repeating the procedure. What happened what the second chime did not happen until the very last try.
Thank you very much. The second option worked. This was after I tried all three options few times. The 3rd option I think set it up as immediately afterwards I tried the 2nd option and it worked!!!!. I dug a little deeper and found information about the display cable and that it can become loose. I simply tapped on the bottom of my MacBook a few times in the position of the cable and suddenly, there was life! Used the PRAM solution and it worked! Any help would be appreciated. So grateful for this post. I was panicking. The 1st solution worked for me. Pressing shift, control, option, and power button at same time for a few seconds.
Then, turning comp back on. Everything is back to normal. I got the dreaded black screen on my MacBook Pro purchased None of 3 solutions worked for me after several attempts and reading suggestions provided. I contacted Apple Support who for the most part had me do the same things but none worked. The Support Tech was kind enough to help me schedule an appointment at my local Apple Store and got me in the same day. Again no luck at the store but my screen was beginning to get more white screen when rebooted to the point of a scrambled like screen this was about 6 hours after getting nothing but black.
Prior I would get a white screen for a second at reboot and the it went black where it stayed. Being an older laptop I have been already having problems with it. My main concern was my photos and videos which he was able to show me that they were still there by connecting to another Mac laptop. His suggestion was transferring my files to another Mac device which I do not have and would need to purchase.
It seems to be working fine but believe me the first thing I did was run backup! Just be aware you do want an appointment if you go to store…they are known to be booked up to 2 weeks at my location. Sometimes it works and I use my MacBook with no immediate problems and then it just goes back to black screen again. This is so frustrating. I should have kept my old non-apple laptop. I called Apple Support. They got me loading OSX Yosemite or something. The loading bar says it would take 1 hr and 40 mins but suddenly I heard a chime. Guess what? Black screen again with my MacBook running.
The Apple Support person closed for the day while I was still loading the software. I need my MacBook. Can anyone help please? In a past PRAM work but not this time, none of the suggestions worked. I thought all is lost as I recall my daugter dropping my MBP last week. I unscrewed the back and diconnected battery from 30 seconds and once I reconnected and powered it on, I saw the screen light up and all was saved!!! Hope this can help someone, who tried all suggestions above and below.
Believe it or not, dropping it from an inch above the desk solved it for me. None of the resets did. Not sure if the problem first arose because my laptop bag with the computer took a spill. Two wrongs might make a right. Its my work Laptop and we use macs because things like that are unheard from unless you experience it.
I tried turning it on again and waiting for the invisible dialogue box like option 2 said, and tried turning my volume up to see if I could get any noise. The black screen disappeared and the normal boot-up screen returned. I have NO idea why this worked and I have no idea if it can be replicated, but it worked for me! I was in panic mode for greater than a day because my MacBookPro screen was black upon rebooting the computer.
Thanks so much for the great suggestion above about turning off and again rebooting…fixed the problem. I can not thank you enough. Tried these reset methods number of times… There was some improvement, like the Apple logo at the back switching on. But the screen was still black.
But the mac screen was still black. Then I read on some forum, that a problem sometimes is graphic card. So I opened my mac, and graphic card was so dirt, from the heat dust was like a chewing cum. I cleaned slowely, now its working as a new :. You should take it to a Genius Bar or certified Apple support center to get it looked at. Hopefully no water was spilled on the MacBook, that damages a computer. Best of luck, update back when you have a resolution! Thank you for your suggestion!
No water damage. All the best! Tried all of it for few hours and non worked : Still showed a grey screen. Only difference is when I tried connecting the macbook pro with an extended display, the apple logo and progressing bar showed up. Anyone might know whats the problem or have any solutions? Turned on my Mac, black screen of confusion ensued. Found this website, tried all three to no avail. The first step worked.
I guess I should have started with it plugged in like the directions said. Thanks for the help!! Pls help!!! I need it for work!!! Help me pls!!! Update: got the second boot chime through the PRAM reset, but it still has the illuminated black screen. I tried the PRAM reset and the second boot chime never happens. The screen is completely black but it still is illuminated and the brightness keys work for it. This happened after waking from sleep mode to a frozen screen, which just went dark when I rebooted it. Another option would be attempt to use an external screen, like a TV or a monitor, if you have the cable to connect it to another display.
Sometimes that works.

May be a trip to the Apple Store to have them run a diagnostics test on it, there is a small chance of GPU failure or hard drive going bad. Same happens after shutting down. When I came home after school this black screen happened. Every once and a while I on the bottom of the screen I get a little white line flashing. Is there another way?
When using an external display via the the Thunder cable, I was able to see the login options, my account and guest account. When I typed in my password it started to load. I tried logging into the guest account and it was the same thing. I was using the computer yesterday, opened it today and black screen of death. Any suggestions? I had reoccurring issues every couple of weeks with these symptoms and related startup issues.
Thanks for the help — this was awesome. I have tried every single thing known to man and still have the same issue. No apple lit up and screens not coming on…. Thank you thank you thank you!!! I reset the SMC — the first option and all is well again. Much appreciated. None of these seemed to help. When I connected an external monitor to the hdmi port with the MBP already booted up nothing changed. But when booted with the external monitor already on and connected, the external display worked perfectly.
Maybe this was just a coincidence but I thought I would mention it in case it might help someone else. I also changed the setting for the screensaver to run continuuously. I think for my particular MAC it actually got too hot which began this prob. I unplugged it from the power source, let it cool down for a day and then tried the various solutions listed here.
The Power button plus the S key helped shut it all the way down. I waited at least 15 seconds for it to be totally off then hit the power source and waited for the start up chime. I held these down through three or for blackouts the computer whent through. Then it finally rebooted correctly so I released all the buttons and let it finish rebooting properly. PRAM reset worked for me! Interestingly 2 days before this occurence happened I switched my desktop and screen saver to be from an album of extremely hi-res photos.
Wonder if this is possibly linked? The PRAM resolved my issue. My MacBook Pro after a shut down came back up with a black screen… Turned back off I would see a flicker of white and then shut down. I noticed that the panel did not have the lights on the keys and it was getting very hot real fast while in the black screen mode. I tried the first solution, hold down the shift, control, option and power for a few seconds then release. I did that and my Mac is back to normal again.
The Power button-S button-hold the power button thingy worked for me!! Basically I had gone full screen on YouTube and then it had these flashy blurred screen and then a blackout…. Thanks a million this absolutely saved me! The third option took a 2 min but if your patient it will come back. Low-end windows machines are garbage.
The ridiculously careful wording to pretend that all these issues are extremely rare drives me nuts. You know what? Mac OS gets viruses.

Mac OS needs to be reinstalled. Mac OS crashes. Mac Apps crash. Macs get error 36 interacting with any non-mac computer. Macs need plist files remove to fix software issues. Macs need to be restarted to solve issues. Accept it! Computers are complicated.
LG me. Black screen but managed to get it working with PRAM reset for 2 days. Now black again and no amount of suggested solutions work. Apple support not at all helpful, suggesting graphics card needs replacing but not offering to do so. Thank you for the PRAM solution. I have tried everything and no success even tried apple support.
Top of the range mid Mac book Pro and its dead. My MBPR 15 screen goes blank when running imovie. After this I hard shut it down. Sometimes it will come back and others it boots to a blank screen. Forced a shut-down with the power button as suggested and on restart it all came back. Apple error warning said failure to waken properly from sleep. Unfortunately it has come back. I think the system is not shutting down when the lid closes and this is something to do with low battery. I have a MacBook pro and having tried and cried several combinations of short cut keys, stumbled across this website and the PRAM reset worked for me.
You are life savers and uni dissertation savers having written words and I was going to give up and take it to Apple shop after four days of black screen!!!! None of these options worked for me and now when i connect to an external monitor the macbook wont boot. It worked- number 3. Took a couple of goes, I must have been a millisecond too slow a couple times. I had just done the update to the newest iOS and it must have played it up. Thanks for the advice! I have a mid macbook pro and I almost sold my computer as broken until I found this fix.
I could hear the ding for booting, but no display. It ended up being the PRAM reset that fixed the problem for me.
iMac screen goes black. – Mac Questions – The Mac Observer Forums
However, it took some patience because the computer booted halfway before the screen came back on. Had the black screen issue with my 18 month old MacBook Air. Tried all the suggested keyboard sequences unsuccessfully and was about to give up. Then tried the final suggested one which was the PRAM one…. My macbook pro 13inch retina 2 years old come march has been playing up for last 6 months. Keep getting the screen going black, I have done all the above fixes worked for a bit other times it doesnt fix it all.
It works fine when connect it to my tv via HDMI screen still black on laptop but can at least use it. I think mine is more hardware focussed, so I be interested in finding out if anyone has actually had to get the screen replaced or taken to apple repair centre and had an idea around actual costings? Am debating just buying a new one and keeping this as a spare hook it up to a separate monitor use as a steaming device instead. PRAM worked for me. That happened to me during exams time, you just saved my life!
I have literally tried everything mentioned here. I even restored the dang thing…. PRAM reset worked. My MacBook Pro booted to a black screen after upgrading to the El Captain operating system leaving me concerned. I went into the Internet to learn from those who have had similar experience, thankfully the PRAM reset option restored my MacBook to its normal booting screen.
I have a Macbook Pro and I tried all 3 options, but non of them seem to be working. Ive tried the PRAM reset, but it only makes the booting sound 3 times. Nothing actually happens. Third option worked the pram worked first time trying it thanks so much. The wife was freaking out good thing this worked. I first tried the SMC reset, without result. I then tried the Keypress Sequence, and the screen came on but with the black-flash problem, so I repeated it, and voila, problem fixed!
Thanks a million. Booted and held option down. This brought up the boot picker and finally brought some light to the dormant screen. The PRAM restart worked for me only after having removed the power cable. I repeated the third option and it worked again, but am worried this is going to become the norm. Anyone else with a similar situation?
Suggestions for a more permanent fix? THANK You- all panic ensued after allowing my 8 year old on my Mac- I totally thought she dropped it and that is why the black screen- you saved us today with this great knowledge- thanks for publishing this freely! Was in a panic because nothing else was working!! The PRAM worked for me. Reset the computer and everything is back to normal. The pram reset worked on my macbook pro.
Thank God I found this post on my smart phone!!!!!
How to Fix a Mac That Stalls on Gray Screen at Startup
Great info guys! Perennial problem with Mac Book Pro retina running Yosemite Best solution after reboot with PRAM or SMC and on encountering a black screen is to close the lid down and make yourself a tea or coffee. When you come back an open the lid the login screen is visible — mostly. Coffee tends to work better than tea. PRAM finally worked for me. Is it not a bit troubling that there are so many people with this issue?! Pretty cool that Apple is still making MacBook Pro that far in the future! Looking at the comments, this seems to have the most success- why not make this the first option?
Number three pram reset worked. Thank goodness. I had the same issue a couple months ago and had t replace the logic board. I had this problem and tried everything here… it did not boot. I picked up the machine and sort of patted down the back, to try to seat any loose chips or connectors. It started up fine. I think the problem was either a loose connector, or possibly since the macbook was near the window it may have been too cold until I picked it up, then it warmed up and started again.
If you have the problem, try hugging your mac. Unexpectedly, this one worked for me. I tried the 3 solutions above for hours I do not give up easily. Then I read this post and applied the same process. I patted the back of my mac book pro, squeezed it lightly, and pressed the power on. Seems to work now Thank you so much the PRAM solution helped. I already had a appointment at Apple. I will be cancelling it right now. So happy:. I had to try it twice though. Thank God for this post the 3rd option works. Life saver as I had a presentation today, with 5 mins to spare my screens back.
Option 3 worked brilliantly the others did nothing unfortunately. Thank you.. I tried the first two options 3 times each and they did not work. This was after i had tried an external monitor as well as the brightness key. The third method worked the second time. After trying the first two options with no results, the PRAM reset worked like a charm!
My blood pressure can go back to normal now! After a few hours my Mac turned on normally…. PRAM reset method worked for me…. Thank you so much man. What is the actual reason for having to do this reset in the first place other than the obvious that it is dark. We have a problem with Office My question is: can we repair the instalation on this product? Any help will be appreciated very much. Brilliant — tried loads of tricks but the PRAM one worked first time- many thanks!!
This was my first problem ever on a fairly new MacBook Air — am so relieved! Any Help. I try to all steps but the third one is work, its very helpful for us.. I reset the PRAM then i got my screen back….. SMC reset worked for me on second try. Made no difference the first time around, so I went to method 2 and 3 without success. Then I tried method 1 again and all is well. None of these worked for me until I saw a similar solution on another forum. Do step 1, then immediately boot using step 3.
This happened to me out of the blue. Option 3 : PRAM reset worked for me. Nothing has worked! But thanks for the help. Mysteriously when I try to Boot up, the computer cuts on, automatically cuts off, then automatically cuts itself back on to a Black screen with no sound that anything is happening in back ground. Same here. PRAM reset worked for me. Thanks just thanks,took the 3rd option that you advised to sort out my Mac air,after the first 2 failed I thaught was gonna be an expensive apple fix,once again thank.
I had this issue after turning the display brightness all the way off earlier in the day. Then it did the trick. Thank you, Marten Otten, for mentioning that in your comment!!!! My screen was black and i didnt hear anything, just the apple sign was showing me that i had a power supply! I have a Mac Book Pro. Great article. It would turn on, chime, then the screen would go grey. Nothing worked until I tried the tip about holding down control-command-p-r. PRAM Reset tip worked perfectly. Saved me a trip to the Apple Genius Bar! Thank you so much!! I was really worried for a second.
I tried all your options and it is working properly again now. Anyway thankyou!! Tried everything on my macbook pro, but nothing worked until I followed the suggestion to hold down the Shift key on the reboot. This finally brought up a login screen in Safe mode. I logged in twice to reach an OS update screen. After updating, the macbook works again! Thank you very much.. The first option worked for me after having water damage in my mac book air , I tipped it upside down and let it dry for about 5 days , turned it back on and my screen was blank bt the power up sound chimed. Mac was booting but just a grey screen displayed.
Went through all your steps and the last one fixed it. PRAM reset. Life saver! Thanks so much. I tried all of the options and then tried it all again and all sounded positive on the third option until nothing else happened! Was getting very scared and then sent the laptop to sleep and then force restart had to guess because obviously the screen was all black and then it worked!!!
Seriously after 30 mins I was so panicked. PRAM was the only thing that worked for me. The PRAM reset worked! Hi, I have the same issue. None of the above said methods worked. Hope you have resolved it. If so could you pls tell me how to beak this black screen curse? I tried the first and the third method. I dont know which one worked. Fingers crossed i dont run into the Black Screen Curse again!!!! Any ideas? Thank you so much!!! This should not happen on a machine that costs so much. Only the last one, the PRAM reset worked.
But it stayed black this time. Now fine! Tried everything…finally came across your article and the PRAM reset worked! My wallet and I thank you so much! I tried everything. Was getting a black screen nothing with flashlight…dead dead dead screen with no lid light when shut.
Hopefully it is more than a temporary thing. Thanks a bunch!!
My problem began when my battery ran out. I plugged it in and rebooted to a black screen. I tried the three suggestions above several times and when it seemed like it was working, I kept getting the password reset window. After I reset the password I had to restart not other option it seems which then brought me back to the black screen, trying one of the tips, then reset password and repeat.
The next screen asked me to disable the FileVault. I did then it restarted and voila! Maybe someone can clue me in. For the record, new iTunes recently installed. After the above fix, Aux monitor went black, macboMA stayed on, forced quit iTunes and everything returned to normal — just saying. Suddenly, without warning my screen went black. I was beginning to panic when none of the options had appeared to work. Agree with the others that you have to be precise—hit all 4 buttons at the same time as soon as you hear the reboot sound.
PRAM worked. Have to be precise and very quick on the fingers to make it work. Thx again M. Nothing worked. Even multiple attempts at PRAM reset, starting in recovery mode, above tips. Several moments went by. Then it woke up, screen and everything! Thank you sooooo much! The PRAM reset worked. I have a lot of scripts and projects on my mac. You are a life saver! Glad to hear you have your Mac working fine again, the black screen on boot can be pretty frightening until it gets sorted out.
I plugged my MacBook into a projector. The image showed up on both screens then I unplugged the projector and now it works great. I was freaked out! I have an older MacBook Pro, and as soon as I did this it booted right up! I was freaking out when I turned my Mac on and had a black screen as I had a document for a client I need to send out tonight. I went through all the recommendations and the PRAM worked.
Thank God! Yay thank you!!!!!! The first 2 ways did nothing for me…the PRAM reset finally worked! I have a MacBook Air : randomly it turned on to a black screen, but the pram reset got it back to normal! The first option worked, but it took a while for the screen to light up, since I heard it thinking I gave it time while I read the next options. Then it came on! But when it did, it was at a password reset promot. I had no options but to give it a reason I needed to reset my password.
I hit the back arrow and it froze. I rebooted and the screen took a while on black so I googled thr password reset prompt and read about a backlight issue, where you can see that the screen has content if you shine a light through thr Apple logo. It said at the password prompt to move mouse to top of screen to get the menu and pick restart.
Then, shine the light through the back to pick thr user to log in as and type the password. Did so, my account needed an update so it loaded a while, then I was back in business. What a weird combo of problems. I assume all related, but still perplexing! Was thinking of how to DHL my mac back to apple in Chicago and i came across your post. You saved me a whole great deal. God bless you so much. My mac stated up fine after that. The PRAM reset worked on the third attempt. Logon screen came up and everything seems to be OK, so far; I cannot understand why this issue came up! Thank you so much, i like just bought my Mac 2 months ago and I was scared it was damaged.
The PRAM option worked out for me. All they did was make the keyboard lights not work anymore. Then I turned the computer on wait for the chord and plugged in an external monitor, and just like that everything is fixed! That is, until next time I suppose…. The PRAM reset worked for me. My MacBook started normally for a few days and again had a black screen start up. The PrAM reset worked again. Do you think I should take it in to have it checked out? Aaagggghhhhhh my life! YOu have to be Patient before you can actually see the bootscreen for Mac to load back normally!!!
I was able to solve my boot-to-black problem, but only by deviating from your instructions. Pressing the reset-SMC key combo before booting, as per your instructions, did not work. Pressing the same key combo when the computer was already on, but with black screen, worked. I tried all three solutions and brightness as well but none worked for me.
Kindly help me if anyone has got other solutions. Just like to say a very Big thank you for the help that I saw on the blank screen for MacBook Air it did the trick with pressing the shift control command power button it now works Thank very much Jason see. I tried the first soultion, it worked. However, after around 20 seconds it went black again. What should I do now? Also removed items from root library startup items, and user startup items.
Basically a bunch of third party software extras. Then we restarted normally and everything was back to normal. Thanks to person above who suggested contacting Apple support. There was no charge either! This starts your computer without 3rd party startup items. We then went into library folder and removed some items. The third time I tried option 3 it worked! I was pulling my hair out until I found this! Not sure about this, but am suspicious. Well I tried all three and got nothing! Everything did work to knowledge as for the resetting but could not get the black screen go away.
Thanks guys! TP — turning off FileVault was how I was able to get a normal boot. First time for me and my MacBook Pro was bought in Thanks for typing it all out. I was on my phone searching for the next thing to try when the apple icon screen popped up. So be patient! My first Macbook after running from Windows 8. She is not technical, so I have to handle it. Had to use Google to find this webpage, again. Both times it was the PRAM reset that resolved the issue. It would be nice to know exactly what causes this issue. Some of us have much more pressing issues that are causing the same problem and those of us that do are obviously unable to fix it using the same method.
Good gosh. We get it. The third solution worked for me, PRAM reset! And to add to my previous post, my MacBook Pro now boots up so much quicker than before….. Tried the first two options and was beginning to lose hope but the third one worked a treat…. In a diff sequence. I shut my mac down. I was pressing the keyboard sequence and then pressed the power button. Worked amazeballs. The chime came and then the screen went completely black looked like it was turned off and then a louder chime followed with apple logo then the log on page.
I tried your sequence of steps 1, 2, 3 and then again 1, when my Mac finally booted up with display!! None of the solutions worked. Not good enough, complete waste of my time. Heard good things about Apple so I bought one but will never again after all this rubbish. Cheap laptop that looks good. I had the same issue with my iMac and Apple support walked me through the fix yesterday…. Shut the computer down by holding the power button for 10 seconds 2.
Restart the computer and press shift at the same time until you see the progress bar start moving 3. After a moment, you should see the spinning beach ball 5. Let it finish. After that it should go to your normal desktop and the issue should be fixed. If your screen goes pitch black during this process, hit the space bar.
Thanks a lot!!! I must say, after a weekend of camping, coming home and totally crashing in the bed and waking up 12 hours later at 4 a. Miraculous and thank you! My computer has been sitting for literally YEARS because I thought- even after bringing it to a Mac expert friend- that the screen was dead forever.
I wanted to try one last time to connect it to an alternate screen and when that failed, I googled black screen and found your page. I used the key code s! Opening this computer is like a time capsule! I had the blank screen after leaving the MBPR in a deg. When I opened it again, I found it hat shut itself down. I tried all the methods here several times without luck. After leaving the laptop unplugged, open and on but with a blank screen for a few hours, I closed it. When I opened it again, the login screen was displaying again. My guess is that it was a battery controller issue that shutdown the machine Monday evening at due to high heat or low power running fan?
Thank you u so much for this article — solution 3 did the trick in my case! In my case, none of the 3 solutions worked, and I was afraid my mac was dead, completely. Hey guys. I just encountered this problem with my MacBook Air. I used it last night and closed the screen just fine. When I tried booting it in the morning it booted to a black screen. Please please please help me. I have a new MacBook Pro. I am so glad I found your tips. This finally worked — but not the first time I tried it.
None of the other options worked. I have a late MacBook one of the white ones. In my case, its Snow Leopard. If I reboot with the installation CD in the laptop, the backlight works!! However, partway through the install the backlight goes out and the problem is returned. This does tell me one thing: that I have a working inverter. I think that the next thing for me to try is installing to a new or zeroed-out hard drive.
I was wondering whether anyone can add anything to this.? Anyway, I will update this reply with progress updates for the community. Gys neither of the above solutions helped me. I use both windows 8. But I can see the cursor moving over there. No problem with Mac OS.
Easy fixes for Macbook black screen
Can you just help me out gys..!!! Thank you thank you… New to MacBook Pro, only had it a week, black screen prior to urgent work commitment this morning and thought what on earth have I done… Tried all three suggestions twice, second time around PRAM reset fixed it…. Saved your file and hope it is not needed again any time soon.
Like Joe near the top said, none of these worked for me either. Any other suggestions? As is mentioned in the article, if you have tried all of these solutions and the Mac screen is still black, it boots to black, and the screen and external displays are always black, you may have a hardware problem or a bigger issue with the MacBook, iMac, MacBook Pro, MacBook Air, or Mac Mini.
In that case, you should take the device to a repair center and have them determine if there is hardware failure. Any Apple Store can diagnose hardware problems for you. Best of luck! I had this on moving my MacBook Pro and was a bit panicked — working down the list with no change I was really worried — fortunately the PRAM reset listed as the final option worked!
Great stuff and thanks for this :. Unfortunately the resets are not working for me, I will contact Apple to solve it at the hardware level as mentioned here before, but in the meantime I can get my internal screen back this way:. Close the lid of your computer 3. Open it again 4. Plug a display adapter in the mini-port, wait for a couple of seconds 5. Unplug it again. OMG this worked for me!!!
