Sonoma 14.1 Issues! Black Screen after update OCLP 1.1.0 Details + Fix 

My 2015 iMac 5K was stuck at Apple logo with no progress bar and recovery method worked like a charm and I am back in business. Thanks for the quick video, it is much appreciated! And if anyone from OCLP teams sees this, we are all very grateful for your insanely hard work.

I would like to thank all the developers that allow those of us with old macs to update to the last operating systems. I only saw this video after starting to update my iMac 10.1 and after the fiirst restart it failed to install Sonoma 14.1. Tried a second time to install and this second time everything worked as expected and I'm now on Sonoma 14.1 on a 14 year old iMac, upgraded last year with a 1TB SSD.

Really appreciate you producing these videos so promptly. I just upgraded my Mac Mini to Sonoma and went with first version. Was waiting for your video before proceeding 🙂 Many thanks for what you do. 🙏

Thank you. You always speak with clarity and in a practical thorough way. Just know we really appreciate you.

Many thanks for your advice and late night work. Certainly I can wait…and still no action without your assistance. Always good to wait a while before installing system updates.

Always the truth and a honest review or finding solutions for serious issues from Mr. Macintosh! Kudos 😎

I love you Mr. Macintosh. You saved me from having to reinstall the OS because when OS Sonoma was installed it would get stuck at that 25-30%. Your instructions helped me boot in and i was able to fix the issues that was causing the issues. Not only that, i was able to save all of the files that were on my computer. Well done. You are a life saver. I am subscribing and following you. Thank you again.

Just updated OpenCore Legacy Patcher 1.2.0 this morning and waiting for the results of your tests to upgrade to Sonoma 14.1 Refresh, Refresh, Refresh,… Thank you for your work!!!

And once again, you are the savior of the day! I encountered this issue with my late '12 mini while updating to 14.1. It got stuck, and even though I followed the steps you provided, the problem persisted until I tried starting in safe mode. Now, it's completing the update in that mode. 😅

Firstly, thank you once again for the detailed guide. I bit the bullet yesterday and ended up having the Apple logo + 1/3 stuck loading bar. Tried rebooting several times with no luck. Today saw this video and solved the stuck boot problem. 2012 15" Retina MacBook Pro, had to enter safe boot and reapply the Root Patches (luckily I have a Thunderbolt ethernet adapter so there were no major issues). So far it's all working ok. Thank you!

Your instructions corrected the no WiFi, max screen resolution and other issues with my 2015, MacBook Pro 11,4. Afterwards, I took the option to update to Open Core 1.2.0 with no issues. Thanks much for making this video.

Thank you for the solution! I was stuck on the boot screen after installing the root patches. I have the same 2017 model, and when I bought it 6 years ago, I also bought the USB-C to Ethernet adapter in case I might need it one day. Six years later, today was the day! :D

I really appreciate your detailed walk through it helped me rescue my wife's 2015 MBP. It got stuck at the login screen and had the same no wifi issue you showed so was not downloading the KDK. Used an ethernet dongle following your instructions and 👍

From today you are a hero 🎉 Worked. Not on the OCLP icon with the black flash symbol, but on the OCLP icon with two hdd symbols I could enter. Happy new year later 🤩

This is the second time i got caught updating too quickly and the KDK fixed the problem. 2013 Macbook Air. Thanks Mr. Macintosh. The 3rd option worked using a usb to install the kdk since wi-fi and ethernet did not work in safe mode and would freeze after i connected a usb hub. I swear i am going to wait 2 weeks to a month before updating going forward. I thought i was going to have to reload everything but i didn't lose any data. Awesome Assistance - never heard of Bless before but then again only used mac for 2 years so.......

You are amazing! Thanks for posting this wonderful video. Everything you said worked perfectly and now my 2008 MacBook Pro is up and running again on Sonoma 14.1 😊

GARY!!!!!!!!! You my friend YOU are a LIFE SAVER!!!!!!!!!!!!!! Thank you so much!!!!! Never had an issue on my mid 2011 27" Imac till this time and you save me an my beautiful Imac! Many thanks and keep your amazing work!!!!!

THIS WORKED!! Running a mid-2012 retina MBP. Kept getting stuck on login after updating to 14.1. I tried everything to fix it. This was the only thing that worked. Thank you thank you thank you.

I have an 2015 MBA and was thinking about updating from Ventura to 14.1 earlier but I guess I should wait for now. Thank you for the video

So I tried the fix and it appears that everything is working again! I’m on a MacBook Pro 15” Retina 2012 and running MacOS 14.1!!! Unbelievable but amazing! Thank you so much for the video and the fix! Between you and the awesome developers at OpenCore I think I can keep my Mac going for a couple more years and save some big money!

Mr. Macintosh ... you are a god (and all the other developers/contributors to Opencore as well 🙂. OCLP has allowed me to 'recover'/reuse multiple OSX machines over the last couple of years, including this MBAir 6,2 that I'm happy using right now that I had thought was wasted 4 years ago through a failing battery. OCLP worked wonders with it, and even with the MacMini 3,1 that I have just updated with an SSD and Sonoma (NB: anyone trying that would need to buy a USB 2.0 dongle to get around the USB 1.0 issue). This troubleshooting video has allowed me to just repair the 'bricked' iMac that is my main machine that just went haywire with the Sonoma 14.1 update. Keep up the AMAZING work. We will always be indebted to you all (round of applause 🙂.

Well, I just ran into the dreaded blackscreen at login with sonoma on a 2011 macbook pro... ur advice and steps saved me a reinstall and enabled me to login and reapply the correct root patches ...thanks!

Thank you. Truly 🙏🏼. So, I do not have an Ethernet dongle & I did not have functioning WiFi either of course. But I do have an iPhone with a hotspot & was able to plugin the iPhone & connect via USB to the hotspot which allowed me to perform this workaround. Just thought I’d share in hopes it helps anyone else! It’s been said before by many, but thank you, so so much. For this software & especially for this life saving video. I installed the latest update without even thinking & that’s not how I normally go about things but I could not boot up past the login screen & safe mode would not function either. THANK. YOU. for this quick workaround & clear explanation of the steps/code. I have the exact same model as you display in this example & everything went flawlessly. For now. Will be on the lookout for future patches as they come. Thank you again 🙌🏼

-You sir are the absolute best! Thank you so much for your time and effort by putting up this video and help those in need :)

Great Video and solution! I had exactly the problem with a MacBook Pro 8.1 Late 2011, no Network due to non working WiFi drivers which prevented the KDK to load during root patching. Mac would not boot and show Apple Logo and no progress bar. Followed your instruction and used Ethernet to get it back working 😀

As always, thank you very much Sir, for your support, I think I will wait until, the next OLCP will be released and fix the issue .

Thanks for this video! Three little notes: 1) I thought I'd prepared sufficiently by installing OpenCore Legacy Patcher 1.1.0 over Ethernet, and just in case I manually installed the KDK for 14.1 too, before upgrading from macOS 14.0 to 14.1. Still, I got the 30-40% progress bar issue while upgrading the OS, and had to boot to safe mode, which let the upgrade complete. I could then remove the root patches and reinstall them, and everything worked fine in the end. Note 2) The system is very slow at the login screen in safe mode on my unsupported MBP 15" late 2013 when entering my password. Might affect all older machines and not just mine. And note 3) If you run Boot Camp, the EFI partition might show up labeled as "Windows", but the icon is the same design as shown in the video.

Thanks for posting this Mr Mac. Although not a black screen, my 2016 Retina Macbook Pro would load to the login screen, let me login but then freeze with the backdrop photo and my user picture. No progress bar or anything. Followed your video on my phone (which I had to use as a wired access point) due to the Wifi issue and all worked out.

Wonderfull. Thank you very much. My MacBook Pro 2015 is now back to life.

I thought that officially your MBP Pro 2017 is not supporter, according to the list I saw. Something to be aware of. Thanks for making the video helping other fellow humans :)

Thanks for the heads up, I will hold the patch until the fix is available. Cheers.

I had the stuck at 30% screen while updating last night to 14.1, rebooted in safe mode, quick verification of my user, the machine took over and completed the install after that and all is well. thanks to Mr Mac for the safe boot tip in previous videos to get me out of a sticky situation! Cheers

MacBook Pro Late 2012 failed with the 14.1 update, I literally follow every step on this video and was unable to fix it, I made a fresh Sonoma installation and back to normal. Thanks for all the help Mr Macintosh, I'll be waiting for your updates! 🙂

I have MacBook Pro 15” mid2012 working on Sonoma 14.0 & OCLP 1.0, i had no issue with this so I’ll just stay put for now when everything is fix. Thanks man for the info.

I did the update last night on my 18,3 iMac. No issues whatsoever. Running great, knock on wood. Thanks for all your great videos.

My 2012 MBP was on 14.0 and I updated to 14.1 via the GUI and it wouldn’t get past the boot screen. I launched into safe mode with shift key, removed root patches, rebooted back into safe mode, applied root patches and solved! Now happily running Sonoma 14.1, 2.9GHz i7, 16GB RAM, 2TB 870 SSD 👌

i have not updated sonoma yet and will wait. i do have the oclp 1.1.0, but stiil it's working fine so i will stay put til that's ironed out....thanks for posting this as i was planning to update later today on my 2012 13" mbp.

Thank you! Had this problem on my iMac late 2015 and this saved my day

Thank you! Thank you! Thank you! You give so much of your time to help this community. I'm back in business thanks to you!

Thanks for a very fast helping video! ❤

I’ll wait until everything gets fixed. Thank You Mr. McIntosh for all you do

I always wait to update until I get the green light from you. Thanks for all you do. I enjoy the channel.

Worked for me after I made the mistake of installing 14.2, lol. That happens when you rush, but I loaded a snapshot and installed 14.1. It works like a charm. Thanks, brother

Thank you so much! You solved my problem! I were desperate

Thank you Mr Macintosh for the warnings. I upgraded anyway from Sonoma 14.0 to 14.1 with OCLP 1.1.0 on my MBP 8,1 13" 2011 using ethernet connection - without any problem - . Not much risk taken here as system is installed on separate SSD and data stored on second SSD replacing optical drive. Wifi and bluetooth working fine when switching from ethernet to wifi after install.

i had exactly this problem, it helped me a lot on my 2010 iMac 27". Thank u!

I have my Macbook Air 2017 and this happened to me, I tried holding the shift button after rebooting from stuck progress bar and luckily the login screen showed up and I was able to apply patches from there.

Thank you. My Mac back in business 🤝 Sonoma 14.1 on MB Pro 2015 early work well

I have a collection of 20 Pros, Airs, and iMacs 2009-2020. I updated them all to 14.1 last night and today. Some went smoothly and some were hard. All were successful in the end. Two suggestions that have helped me. 1. Keep an installation of a previously working system (like Ventura) on another volume so you can always boot back to that. 2. Download the installer and build an installer disk with OCLP and then boot with that and start an install to your current installation. 14.1 sees that you are installing to 14.0 and does an upgrade. Lastly, if it hangs you can sometimes power off and restart and hold down the shift key and limp up to safe mode, install patches and then reboot. I’m surprised by the amount of variations from one machine to the next but that’s the fun right! Sometimes you just have to tinker.

omg. thank you so much for this video. it was those damn kdks again!

Thanks for the headsup :)

Thank you so incredibly much for all your amazing tutorials. I’m trying to Lear about openCore and fixing errors etc for when I may need to use it. This may sound odd but is there any chance you have a video about what to do to avoid the black src teen and issues etc in the first place? Or are the people at open core doing something that will prevent this problem from occurring ( I really hope that makes sense!) thank you so incredibly much again

YOU ARE A LIFE SAVER. Many many thanks!

This guide saved my day! I was already reformatting mac trash can mac pro...

Thank you for rescueing my iMac 15,1!

Thank you for all you help

Glad I caught this video in time. So precautions can be taken. 😅 How can I troubleshoot or fix Bluetooth issues on 14.0? It's the only thing not working it's just perma toggled off. Root patches are installed too. I'm on a MBP 6,1 mid 2010 laptop.

Thank you so much, very helpful video 👍💯

My MBP 2012 already had Sonoma 14 and OCLP 1.1.0 and the 14.1 update kinda bricked my computer. I followed the Mr Mac's fix suggestion to no avail. Since I had a BOOTCAMP defunct partition wasting 400 GB of disk space I took the opportunity to do a fresh install of Sonoma 14.1, OCLP 1.1.0 and reclaim my bootcamp disk space. Everything worked perfectly. 👍👍👍👍

Thank you Mr Macintosh for saving me hours of stress.

Thanks for the big Help 😊you are the best Mac Hero

Thanks so much. Worked perfect on MacBook Pro 2017.

Having encountered a serious problem updating my M1 MBP in Monterey, which required the Genius Bar guys to “revive” it with a forced Sonoma install, I will definitely be avoiding this update. Hope this all gets sorted out soon.

Good to know, great video! ❤😊

Thank you very much!!!

Thank you!!

Thanks a lot. This one saved me

Your fix was amazing, the safe boot mode was enough to solve my problem. I've just noticed that my MacBooks wasn't able to connect to my iPhone's personal hotspot. So if you have any fix for that, it would be very appreciated. Thanks

First off, i have to say that this video and all your videos are absolutely awesome, and help a great deal! I have a strange issue that's very close to this one. I'm on a late 2013 iMac running Sonoma 14.4.1, using the OCLP 1.4.3. The computer was running laggy after reboot, so i ran the patcher and it would not let me in past the login screen in normal or Safe Mode. So i did the "bless to the last snapshot", now i don't even get to the login screen, i instead get the back screen when booting, but i can now get in Safe Mode. Really unsure what my next steps are from here? Would it be possible to run the bless to last snapshot again, or plug Ethernet into the iMac and run the patcher again, or is there a third option that i can try to resolve the issue?

Have both a 2014 i7 Mac mini and a 2015 i7 MBP running 14.1 .... both perform VERY well by the way.... the Mac mini had not issues using the OCLP 1.1 update but the 2015 MBP gave a black screen until I followed the instructions here to get it back and using ether net to get the required older file.

Great video. But why is the GPU in your 17“ 2011 not failed? Is it because the issue is only with the standard AMD GPUs and not with the high end chips back then?

Works. Thanks.

Good video. Can you make a video on using OpenCore to run old versions of Mac OS on newer Mac?

i will also say that i am just thankful to the oclp team for extending the life of my mac. i am in no rush for any update nor new os so they can take their time and it's fine with me.

Thnks bro it’s working

You're the greatest!

Good afternoon Mr. Macintosh, Thank you for the wonderful explanation. I work with a Macbook pro Mid 2015. I tried everything several times, as you explain it so professionally. But, if I start it up like you did, I get the same screen, but I only get the white bar that always stops in the middle! What else can I do? Thank you in advance for your help. Kind regards from Belgium

I got the “40%” lockup after leaving it to upgrade overnight. Had to hard switch it off. Ended up rebooting using the Sonoma installer USB drive. Booted using that stick’s OC EFI, but into the actual Sonoma volume. Redid the root patches while in there, shut down, and removed the USB. Start up again and things worked as intended-OC and a correctly patched internal installation.

Many many thanks!

How important is it to update the OC BootLoader from 0.93 to 0.95? I have successfully installed Sonoma 14.1 with OCLP 1.1.0, OC 0.93 BootLoader on my iMac (Model 15,1). It's a clean install on a 2nd internal drive on my 2014 iMac - so far no issues. The other internal drive has Ventura 13.6.1 w/OCLP 1.1.0 working without any problems. Thanks for the great help videos, Mr. Macintosh!

Hi! so I am in kind of a different issue... I have a 2016 MBP with TB and TouchID, version 1.1.0 of Opencore and 14.0 MacOS (even tried 14.1) and the patcher, when applying root patches, only detects and installs patches for: "Graphics: Intel Skylake" and "Networking: Modern Wireless" but nothing about T1 as I could see in your video. Have you ever seen this? My touch bar is blank, BTW. Thank you so much in advance. Thanks!

2013 iMac and 2015 MBP here, installed by downloading and creating a USB stick of 14.1. The new KDK was installed from there so no issues for me. Hope this helps.

I wish the next OCLP version also tackles iMac 2017 5K 27-inch with External SSD Startup Drive. I met all problems mentioned here on Sonoma 14.0 and 14.1.

saved me on an old mac pro 5,1. thanks!

Thank you Mr Mac! So this just affects Sonoma? I’ll hold on my current Ventura build till you give the “all clear” signal.

I've got five elderly machines with Sonoma 14.0 and OCLP 1.1.0. The two of them connected via ethernet (Mac Pro 5,1 & MacBook Pro 2010) worked fine upgrading to 14.1. The other three on wifi (MacBook Pro 2011 16Gb, MacBook Air 2012 16Gb, and MacBook Retina 2013 16Gb) all crash on boot after the update.

Works perfect! on MacBook Pro Retina 2015 15" with AMD Graphics

Thank you!

This happened to me last night, what I did was to use my working recovery drive's EFI to boot into the system. It gave me a message saying the root patches were wiped out and it needs to be reinstalled. I did that, restarted, and it worked fine 👍🏽 Edit* I'm using Early 2015 MBP 13" I updated to OCLP 1.1.0 and did bootloader and post installation BEFORE updating to 14.1

I just had issues, and I had to reboot my 2014 13" MacBook Pro into Safe Mode, in which I could log into macOS, and then the Post-Install progress startet. Past this, I was able to finish the process in a whole which includes the post-installation of OpenCore *.* ... be mentioned that I updated to OCLP 1.1.0 BEFORE I hit the update to Sonoma 14.1.

This didn't fix my issue. I am still stuck at about 25-30% status bar. Wifi isn't working. Will there be more direction for those with a macbook pro from 2013? Maybe my issue can be remedied with a wired dongle? Should this be ethernet to usb? Many thanks!!!

Thanks :)

Question, If we do the OCLP update first, will the 14.1 update go well, or will we have to go through this procedure?

I wish I could have seen this sooner, I already wiped out my 2015 MBP and back to older version

if you're like me and you reset the NVRAM as a part of the regular troubleshooting steps, i had to jump into internet recovery. internet on my 17,1 imac worked all good in recovery. it prompted me to reset my password, but i chose that my keyboard was having issues just to avoid messing with my user accounts, which told me to turn off filevault. i did this, and i stopped getting the prohibited 🚫 symbol, and i was able to get my EFI boot screen back, allowing me to then open 14.1 recovery.

because OCLP 1.1 forget include KDK 14.1 23b74. If you reboot error, update kdk to 14.1, then patch. That' s ok. Thx, mr.mactonish , you are my god.🎉

I see that you're having the exact same Boot Logo issue (missing/order reversed being displayed before the boot picker instead of after) with your MacBook Pro 2017. Did you manage to fix it somehow?

I had issues with 14.0 and was thinking of reverting to Ventura. However 14.1 is stable for me!

Hi Mr. Macintosh, I'm wondering if the suggested fix would work if upgrade from Ventura to 14.1 failed? I used to run Ventura (installed using OCLP 0.6.4 April this year) on my late 2012 iMac 27" prior to the upgrade. I built a Sonoma 14.1 installer on USB using OCLP 1.1.0. The portion of installing from USB seemed to work but I'm not able to start my iMac when I try to boot from the hard drive. The progress bar either gets stuck at 1/3 or 1/10. I'm wondering the suggested approach only fixes upgrade from 14.0 to 14.1 or would work in my scenario as well. I appreciate your reply or any other suggestion you may have.

Hi, great videos thanks so much for providing such great instruction. I followed one of your previous videos to install Sonoma on my iMac 2010 via USB, but when I clicked the EFI option in Recovery... the screen went black. I restarted but it seems that I cannot get into Recovery at all now. I've tried holding Option on restart multiple times, Option-R, resetting the PRAM, resetting the SMC, but no matter what I do it seems that I cannot get into Recovery at all. I have pulled the SSD and tried installing high Sierra onto it from a mac pro with Monterey but that was unsuccessful as Monterey is too new apparently (even with a patcher installing it direct to the SSD). I have also created a bootable USB with Monterey and also another with High Sierra, but it seems the problem is that I cannot get into Recovery or see anything on the screen when I restart, in order for me to do anything. I have even pulled both SSD and HDD, replacing the HDD with a drive I know has High Sierra on, but again, black screen no matter what I do. I have tested the keyboard, working OK, The screen does fire up as I can see LCD illumination but I do not get any options. Would you be able to suggest something else? Thank you! K
