Do you have a 27 inch iMac that all of a sudden goes black screen and totally unresponsive? This happen to me too and eventually, the iMac wouldn't even turn on!! (or at least the screen wouldn't). So after tryiung some things and having what I thought was smoke come out the back, I finially fixed it! So unplug the imac, remove the cover where your RAM is. Eject the RAM. Plug back in the iMac. Power on the iMac with the RAM ejected. You'l here a long tone and might see a error. Power off your computer by long holding power button. Unplug your computer. Put RAM back in, hold down power button as you plug in the power cord. Worked for me and I have not experienced any black screens since!

I too have a late 2015 iMac 27” & had just updated to Catalina. I had a black screen afterwards. I tried doing to command, option + p & r thing & nothing. This was the ONLY thing that worked + I got to see how easy it is to upgrade my ram. Thank you! 🙏🏼

Ur a Freakin hero! Thought my 2012 iMac had finally given up on me. It’s was going black every 1 or 2 min. What a save! Worked beautifully! Many thx!!!

@frankbiz 3 года назад

This is great that you helped so many people, I'm going to try this on my father in law's 27" and hopefully it will work. I'll be back for a second post next week. Thanks 👍🏻

@michaelsmallcombe7689 4 года назад

Thankyou - middle of a job in the studio and the black problem occurred. I followed your procedure and it all went exactly as you described and, so far, the problem has not recurred. Thanks again.

@richardberry8257 9 месяцев назад

Thank you! This has been driving me mad for months. Tried all the other suggestions then stumbled on this video. Worked on my 2012 iMac 27".

@jeffwestall7964 4 года назад

I was having a similar but different issue with a late 2015 27" iMac. I use it as a second monitor and occasionally it would revert to a standalone computer. When I'd try to reset it as a monitor (Command +F2) it both machines would react, but the monitor iMac would stay black. I tried your solution and so far it has worked!!! YAY! Thanks!

My imac went completely unresponsive during a security update (2020-005 for High Sierra). Unresponsive to any USB input, including keyboard. Tried everything under the sun, your solution is the one that worked. Thank you!! Saved me a lot of trouble. One thing to note though: it didn’t make any sounds and the screen didn’t turn on at all, I honestly thought it might not work. When I put the RAM back it, it took a while but it booted and now it continues the update installation. We’ll see how it goes after it finishes.

@markadairofficial 5 лет назад

Thanks a lot, man. I don't normally trust RU-vid tutorials, but it worked 100%. Thanks for taking the time to upload.

@bryancook4553 11 месяцев назад

Thanks for posting this tip! I was running out of things to try, then I finally found your video. While your tip worked the behavior on my 2020 iMac was a bit different. I popped the ram tray out, pressed the power button while simultaneously plugging in the power cable. The fans started up like an airplane then I pressed the power button to shut off the iMac. I pushed the ram tray back pressed the power button and the Apple Logo finally appeared. I then restarted in Disk Utility mode and ran a repair on the volumes, containers, and then disks. I then rebooted (pressing command+ option + P + R) to clear the VRAM, then rebooted again (pressing shift + control + option) to clear the SMC. I rebooted then booted all the way up to then performed a shutdown. I’m now booted all the way up successfully and upgrading MacOS to the latest version. Thanks again for sharing this fix!!

@aliensporebomb 4 года назад

This happened this morning and would boot with the chime and despite zapping the pram and resetting the smc behaved the same with no video display on the iMac display or any of my two external displays. Strangely enough your video worked. And I'd reseated the ram within the machine within a month or two at most previous. I also blow out the air vents with compressed air regularly because I've seen buildup of dust causing greater processor throttling noticeably.

Outstanding! I was at my wit's end after trying everything I could find online (keyboard options, reboots, re-install OSX, disk repair etc.) about this intermittent black screen on my iMac. Your "cleanout" solution worked beautifully. My Mac is an eariier model 2013, but the procedure with the power cord worked just fine. Thanks for posting this, I was at the point of parting with $$$$ to get a professional fix. Saved me heaps of money. Much appreciated. Lesson learned; keep the vents at the back of the Mac clean and free from dust!

@mitfreundlichengrussen1234 9 месяцев назад

Holy shit - this saved a 2019 27" 5K iMac - I removed the display for upgrading to an SSD - reconnected the screen and got no signal at all on the display (total black screen and only two green LEDs on the motherboard. I have reset SMC, and tried to reset PRAM (does not work since there is no boot sequence). I opened the damn thing again and checked all the cables and connectors under a microscope but could not find any damage.... I always had the feeling that there was a reset problem on the motherboard but did not know how to reset it completely... This "Eject the RAM. Plug back in the iMac. Power on the iMac with the RAM ejected" I´ve done it twice and now the damn iMac, which ate away 2-3 hours of troubleshooting time runs again! Thank you so much for posting this video, and saving a couple of big bucks and hours of sadness.

@alextrexroad 9 месяцев назад

Thank you so much for posting this! I was just about to take my iMac apart but tried your solution before hand and it worked! My computer is an iMac Retina 5K 2019, so if anyone is wondering if it will work on later models...it does. Thanks again!

@Rui1902 4 года назад

Worked for me on my iMac 2017. Different symptoms for me. I upgraded the ram and it would turn on but screen would not. The loud fan did clean the exhaust very well haha.

Δούλεψε μια χαρά στο "πεθαμένο" imac 21.5 (mid 2010)! Δεν ξανασυνάντησα πρόβλημα. Σημείωση: ο Τεχνικός ήταν σίγουρος ότι είναι ο connector της οθόνη ή η μητρική ή και τα 2. Γλύτωσα ταλαιπωρία και ευρωπουλάκια. Thanks Bro!

I have a late 2014 iMac 27" with 5K Display. I've been having this exact issue for months. I took it into the genius bar a couple months ago. They couldn't find anything wrong, but they did say that I have non-Apple Ram installed, and suggested I remove it, but gave me the option. I had them leave it in. Maybe that's the problem? Do you have non-Apple ram? I'll give your fix a try. Thanks!

@raycicin1794 3 года назад

Ok, on my first try i hadn't pushed the ram cards in far enough. It's now 2 hours since following your instructions and no black screen so far. Fingers crossed. Thanks.

@RyneRynie 3 года назад

Just did a similar fix with my iMac. Same issue, black screen, wouldn’t boot up, tried every startup trick and nothing worked. Ended up ejecting the RAM slots on the back and hitting it with an air duster. Tried starting a couple of times and same issue. It wasn’t until I held Cmd+Opt+P+R on startup, that it finally decided to boot up. Got a LOUD startup chime and it started properly. Working fine now.

This fix seems to make a difference. I'll update after some days. If this works I owe you a beer! One week later : This fix surely cured my Mac! Where do I send the beer?

@victorandersen7528 3 года назад

I really hope you’re still able to see this. I have the issue with the black screen appearing, while the system seems to be operating (I hear the sound of the system turning on). I followed all of your steps, and it didn’t work. Just bought the iMac 2. Hand, and used it for about 6 hours until the screen became black. Do you think I have to buy a new Mac, or is there a possible solution? The iMac is from late 2015
