UNSUPPORTED MAC stuck after Root Patch? Here is a solution! 

I didn't upgrade to Sonoma, just to Catalina. After updating Open Core patcher and "rooting", my progress bar would get stuck at around 15%-20%. Your procedure worked flawlessly. Thank you so much!

I have to say, between you and Mr. Mac, I give you guys a 10 out of 10 for knowledge and know-how. When a new ver of everything comes out I usually go ahead with the upgrade even if it trashes my system. I actually enjoy going through the repair procedure. My 2012 MBP is not my only MAC and I love keeping it "on the bleeding edge" 👍👍👍👍👍👍

Simply the best. Full of knowledge. Thanks for sharing.

Thanks a lot for the detailed step by step explanation… really great! 👍

Thank you! I was completely lost until I watched your video. You gave every detail and talked me right through it.

Commands used in this video totally saved my rest of the year. Thank you!

Wow, this works great on OCLP 1.4.3 that bricked my MacBook Pro and wouldn't log in afterward. Thank you for saving me a couple hours and reinstallation of osx :)

Thank you so much! Managed to get my MB Pro 2012 working again with the help of your video!

Great video Thank You Jessie, I always wait on this updates due to this kind of things, thank you for being on top of the situation and helping everyone out.

Help me a lot! Thank you from Brazil

Thank you so much this video just saved me, ran into the issue updating to Sonoma 14.4.

Thank you so much!!! I was stuck on apple logo 14.3.1 iMac 27" mid 2011. You are the one! Awesome work.

JESSIE FOR THE WINNNNNNNNNN. had this issue on my 5,1.. its fixed now thanks to this video😃

Your channel deserves a million subscribers. Thank you for all you do.

Thanks for the help... much more comfortable with the system... 5 thumbs up👍👍👍👍👍

Thank you so much👑very helpful information🎉

Thank you so much for this tutorial!!

I’ve spent this last week trying to recover my 2014 iMac 27 “ after latest Sonoma update. Screen went white lost WiFi and second monitor. Have not tried this fix yet but this video gives me hope.

Thanks! You saved me! Great job!

You are great at this! Thank you for sharing your knowledge and help in such an understandable and easy-to-follow manner. Kudos to you!

I would like thank you for this solutions and pointing the problem. I have 2013 iMac 27”, and two times updated with IOS Sonoma 14.3 after restart got the black screen with apple support text even wouldn’t go to recovery mode.lib was very disappointed because spent so much time to bring the iMac to iOS Ventura. Thank you so Much now I can try again and follow your instructions. Second comment: Finally after watching your videos I was able to install Sonoma 14.3 to my 2013 iMac 27” and learned why the installation was unsuccessful. Thanks to you, Mr. Macintosh and the OCL developers to keep our unsupported Mac a live and running.

Well Done! Thanks for sharing.

Thank you very much. Your video will help me to solve my problem, hopefully. Best regards

Thank you so much for this great tutorial

Hi, really good explanation, many thanks! Just one point to mention - when you were working in Terminal you called the quotation-mark “ a parenthesis, which is incorrect. A parenthesis is a curved bracket, like ( or ) .

Hi, you are really wonderful person indeed and you explained the all the procedure, installation procedure very in detail and I am very surprised. Its really wonderful and informative for me. Thank you very much. So nice of you.

8:13 I have multiple users on the iMac 5K 2017 and selectively boot from the Fusion drive for Sonoma 14.0 on EFI OCLP 1.0.1, or external T7 SSD for Sonoma 14.1. The Sonoma 14.1 on EFI OCLP 1.1.0 has not been stable after boot up, sometimes, it just stuck and t 8:13 he cursor didn’t move (with or without lightning cable), and/or the keyboard LED didn’t respond, a power button restart would be needed. A réinstallation of OCLP from the Installer or from the internal Fusion drive can solve the problem while burning my life for another half-an-hour. Eventually, it looks stabilised but every cold boot takes at least 15~20 minutes to successful logged-in to a user with admin rights. It’s so unstable and I’m not sure the imac will work after the next power off. So, I’ve decided to wait for OCLP 1.1.x or 1.2.x for Sonoma 14.1.x for other unsupported Macs.😅

Great video again that helps to understand the whole background better...thanks for your time and awesome support, Jessie. Is there a simple way to check what's the latest KDKs on a machine?

Thanks for the video, to add, I need to use 1 additional command to fix the issue: ------launch recovery------- mount -uw "/Volumes/Macintosh HD" bless --mount "/Volumes/Macintosh HD" --bootefi --last-sealed-snapshot cd "/Volumes/Macintosh HD/Library/Extensions" && ls | grep -v "HighPoint*\|SoftRAID*" | xargs rm -rf reboot plug in a USB ethernet adapter, and run OCLP to install everything again. work like a charm.

This is an example of parentheses ( ). This is an example of quotation marks ". Good show thank you for the information.

Hi again! Quick update I got in to the OS after looking at the dortania page it has two dashes on the Terminal command at this place “-bootefi” not one dash as on here, but it worked for your demo I have no idea why it made a difference for me!! So now I’m back in and just have the rest of your instructions to follow to hopefully get WiFi back👍 (Opencore version 1.4.2)

Great Tech Support Help!!! 👍👍👍👍👍 & Subscribed!

Awesome as always JEssie. right now i am battling my mac pro 3.1 and sonoma 14 beta. and i have at least two problem children; I have both Asus GTX 1060 AND ATI Radeon HD 5770 installed in this mac. and its boots. but the GPU acceleration is bad as hell atm… I suspect the nvidia web drivers root patched ASWELL as Terascale drivers in the same operation (oclp 1.1.0. having anoither crack at it tomorrow

​ @JessiesFlying YOU ARE GREAT!!!! I followed mr macintosh tutorial 1..2..3..40 times but always failed. maybe it bothered him to do things DONE RIGHT like you did. thanks man!

Like always you are the best !, thank you 🙏

I only have greetings for this highly usefull video. Many many many thanks, you've saved my Old Friend form 2012.

thank you for the video! Question: for every update, it seems that a manual udpate and download of the corresponding KDK is a must. However which should be done first, download to one's computer the KDK or the apple software update? THANKS!

This video just rescued me and my stuck Mac... Thanks!!!!!

Another great video, Tks a lot Jessie, and what do u think about go to sonoma in mac pro 5.1 (now I use Monterey), regards from Brazil.....

Great video, thanks. I acted accordingly and it works. One remark about those Mac which do not have an ethernet connector. I used a USB-Ethernet adapter for my MBA13 2015 and everything went smoothly.

You saved my day twice sir! Good details for the explanation and the logic flow is like the old days, no watering words and waste of time. Thank you and your work is much appreciated.

Job well done and thank you

You are genius! 👏

Hi Jessie: just found your channel! Great vids! So, if you maybe looking for video topics… I have a MacPro 3,1 running DosDude1 Catalina. I’m thinking to move to OpenCore and a newer OS. So one video of interest would be exploring just how old one can go with OpenCore. But another question and idea relates to getting many multi monitors working on an old MacPro. One of the reasons I bought this MacPro back in the day was the advertisement that it could host up to 8 monitors with the then decent ATI Radion cards that came with it. 4 cards, 2 DVI ports each 4 PCI slots, 8 monitors. My question is how to do that today with a new OS in these old MacPros. I have a GTX680 that has 2 DVI, 1 HDMI, 1 Display Port. In my DosDude1 Catalina 3,1 MacPro I have not been able to more than 1 DVI and 1 HDMI working. Nothing I do seems to bring either the 2nd DVI or the Display Port to life (even if I don’t connect the first DVI or HDMI). Maybe those two latter 2 ports are broken? I have no way to tell. Are the PCI slots limited to 2 monitors? Reason I ask is that one of the Apple approved Metal cards is a single width board with 4 ports (don’t recall which kind they are, maybe Display Port), but if the PCI slot only allows 2 monitors, that would not help. So bottom line, the idea for the video would be how to connect 8 monitors up to an old Mac Pro with a new OS using OpenCore. ;-). Thanks!

FYI: rest in the comments: The OCLP 1.2.0 release a few days ago fixes this. this hack/trick is not needed any longer ;) The patcher now detects if you update your macOS via OTA update, and ask to download the correct KDK for your version

Thank you very much, after Update issues to 14.4.1 my mac stuck on the loading Progress bar. With your Help i'm back on my mac

Got the invite for upgrade to OCLP 1.2.0 this morning and went for it. Roulette style as no videos out yet about that new version of OLCP. Black screen after patching. Was running Sonoma 14.1 on midyear 2011 i mac before. Plugged in the ethernet cable, restarted and boom, no problem booting. All functions came back and could unplug the ethernet.

First of all, I want to thank you. I'm hardly a tech guy but your videos have helped me massively with updating my old macs including my 2010 Mac Pro 5,1 cheesgrater and all has been working well until last week with the Mac Pro. I saw this video months ago and then had this problem happen after a PRAM reset last week and it's been driving me nuts. Here's what happened: The problem started after I was prompted to install OCLP update 1.4.3 (from 1.4.1). It wouldn't start up so I reset the PRAM. Then I got the “no entry sign” on my OCLP Monterey 12.7.3 drive (NVMe) so I switched out my RX580 for the mac 5770 graphics card [so I could use the option key] and I removed all hard drives and connections. I did all the steps in this video and all seemed to be going well until it restarted. The progress bar appeared for a second and then said 'your computer restarted because of a problem. Press a key or wait a few seconds to continue starting up” and then it showed a progress bar but not moving. I shut it down after a few min, tried again and I got a gray screen with a flashing “?" (and shut itself off). Then I rebooted again holding option and selected EFI and I got the "your computer restarted because of a problem. Press a key or wait a few seconds to continue starting up." error again. Holding Shfit would not let it boot into Safe Mode either. Sounds like a Mac kernel panic issue like you said here, but I cannot find the KDK version for Monterey on GitHub to do the manual install. Maybe the EFI is corrupted? Maybe it’s an NVMe issue and I should try the repair on the backup SSD in a sled on bay 1 (although everything was working perfectly with the NVMe on a sonnet pci-e card)? I use this computer for music production and was able to go back and use Mojave (NVMe on sonnet card) for now to transfer old sessions to my laptop but I really love using Monterey on the Mac Pro because it has been very fast and stable and I can use the latest plugins and programs. Any advice on what I should do to fix this? I’ll keep searching through your video library for an answer. Thank you! 🙏🏼

Great video, as always! However, I encountered an issue at 4:03 where I couldn't access the recovery screen. Instead, I was stuck on a black screen. I'm really debating whether or not to consider it for my primary work computer. For recreational use, it's alright. Or is it?

Firstly, thanks for the video. These kind of videos explaining things are invaluable. My issue, the latest OCLP 1.3.0, made my previously working MacBook Air on Venture (OPLC 1.2.1) hang on the progress bar, never finishing to boot. I could get into it Mac again with booting from Ventura install, and opening terminal. If I delete the kexts in /Volume//Library/Extensions (apart from Raid and HighPoint ones), I can get it to boot without root patches. I then re-downloaded the OCLP 1.2.1, and re-applied the patches. Still hangs on boot progress bar. So then tried your KDK download for 13.3.1 and re-applied root patch. Still hangs on boot progress bar. (I have internet access via wifi even without root patch btw). I cannot boot safe mode (holding shift), hangs in same place. So it seems that 1.3.0 OCLP breaks something, which I am sure will impact many others quickly. Still working on fixing it myself somehow, but looks like you may need to prep another video soon!! Any tips welcome.

This channel is incredible. I have an iMac mid 2011. I am stuck on high sierra. Will open core work for my iMac?

I really need help. I’m on 14.2.1 . All of a sudden my 2013 iMac has been acting up. I cannot find a kernel for 14.2.1. . It’s been stuck on the boot load screen. I have tried everything. I tried using 14.3 kernel still nothing

Thank you for making my macbook alive again!!!

Thank You!!!

Hi, I recently upgraded to OpenCore Legacy Patcher 1.0.2 on Sonoma 14.0. However, after rebooting, I see the Macintosh HD logo, but then the screen stays black without any further actions. Do you have any solutions or suggestions? I would greatly appreciate your help.

@JessiesFlying Great advice/video, as always. BTW: do you have a list of your Apple/Mac hardware collection?

Hi, first I would like to thank you for all the tips that helped me a lot to install Sonoma on my iMac 2011 12.2, I followed all the steps and the wifi worked but unfortunately the bluetooth is still disabled and I already installed the patch 1.2 and the KDK 14.2 but it was not enabled the bluetooth. If you have any tips that could help me I would appreciate it. Congratulations for your work.

hey there, when i get to the stage where i input the text into the terminal to bless the mount, i get the message “volume could not be mounted: No such file or directory /sbin/mount_apfs returned non-0 exit status Couldn’t bless the APFS pre boot volume for volume mounted at /Volumes/Mac HD: No such process”. I have checked that the commands i entered are the ones in your video with my own directory and they definitely are. What can I do?

Thank you. You are a GREAT teacher and I RESPECT your intelligence! Wow!

hi, there was oclp 1.2 released this morning ... do you have time to take a look at 1.2? ... is oclp 1.2 make it a direct upgrade to sonoma 14.1?... cheers,

You are Awesome :)

Hi. I'm using MBP 11,2, Mac OS 12.7 with Opencore. After updating the opencore, booting stops in 1/3 apple logo. Following your video, pressed spacebar and selected the recovery icon, only gives me a black screen. (After long wait, it boots again btw) My questions are: 1) I didn't tried NVRAM reset or safe mode. What should I do with them? I assume NVRAM reset -> safe mode -> terminal input just as the video? 2) (Maybe dumb question) I can see UEFI Shell icon when I press spacebar. Can I use those 2 line command here too? 3) What if all above won't work? Create OpenCore USB and recovery from it? Thanks in advance!

hi, will there be a new OCLP 1.1.x or 1.x.x to have all these issues resolved? so there is no need to go through all these copying and update... cheers,

NOW I updated my iMac 27' end 2015 and MBP mid 2015 with the yesterday evening published OCLP 1.2.0 to Sonoma 14.1. After installation I was not able to login because the system was very, very slow. On both machines..I can't type in my password. This was possible after a switch off/on restart and installation of the OCLP root patches from OCLP 1.2.0. Now all is fine. Many thanks to all developers.

Big thx❤

hi, first of all thank you for the tutorial, I had the same problem as you updating my 2012 MacBook Pro from sonoma 14.1 to sonoma 14.2, when I updated it as usual it had the root patches to download, when I downloaded them it was presented your problem. I tried your solution but by clicking on recovery 14.2 the Mac freezes on a black screen and after a long time it restarts to the previous problem, how can I solve it? Thank you.

Hey Jessie do know if the HP Radeon 5700 can work in our Mac Pro?? Guy selling one for 100. Also have 14 running great on my 17” MacBook Pro 2011 with out problems now. Backlit lights work. No sluggish

Whenever I try going into the 14.1 recovery from the boot screen, I get a black screen and nothing loads. Any fixes for this?

I have Sonoma in my Mac book air 2017 and my Mac Pro 2010 no issue for now, everything working good thanks for OCPL Pro. next is my Mac mini 2010. saludes ciao,

My experience with an iMac 12.1 is that only a clean install (of Big Sur in my case ) works well with Open Core Patcher Post Install Root patches! But it won't Boot normally. Always starts with the Big Sur install....

After installing root patches after installing 14.1.1 through settings, I get the stuck loading bar issue. I tried the strategy to press space but mine said 14.0 instead of 14.1 like yours, or 14.1.1 that I had installed. Now I’m on a black screen. I’m so confused and worried.

is it possible to install the KDK to the Internal NVME from another MAC-OS booting via USB ? because booting the internal OS stucks.

Hi - I have followed these steps but my problem is slightly different. I get to the boot screen, it starts booting but progress bar makes it only to about half of the way, where it then stalls. Any advice as to what I can do here?

Thank you Jessie for this channel! Some instructions have worked for me. Others not. I had been using Sonoma successfully until yesterday and I’m not sure what action I took (maybe tried a root patch update but not sure). Anyways, I’m still running Sonoma 14.0, and I have external usb with Sonoma installer, opencore patcher, and the last build of the kdk for Sonoma 14.0. I’ve tried doing your “last snapshot” step and I can get back into EFI/Sonoma but the drivers aren’t working (internet) like it was after my original root patch when I first installed it on 2017 iMac. I’ve tried installing the newest root patch, and I’ve tried installing the original root patch again. Still can’t get past the 1/3 complete progress bar after the root patch + reboot. Any help would be appreciated!!😊

Jessie, I came to the "No Boot" video when applying the Sonoma 14.1.1 update and it "stuck" rebooted into "Safe Mode" successful... but than an "anomaly" my machine is a 2012 QuadCore i7 - 2 SSD's "Boot & Media" drives (macSSD & mediaSSD) apparently the 14.1.1 was successful, BUT in the "System information" window and "Startup/Boot" the macSSD appears as "Untitled-Data" not "macSSD" can I correct this?

a very good video to explain the steps, but it seems there is some issue with my mac, it keeps on going to the recovery screen, can you please guide me through how to create a bootable usb disk with the sonoma installer from windows please

Hello Jessie, can you please help me? I’m running OCLP 1.4.3 and MacOS Sonoma 14.3.1 I have successfully fixed the boot problem on my Macbook Pro Mid 2012 and installed the KDK for 14.3.1. However, when applying the root patch after that, the boot problem comes back… Also, the root patch install log shows no line mentioning KDK as shown in the video. What can I do?

So referring to this video, could the new kdk be downloaded (but not installed as I presume its tailored to a specific kernel not backwards compatible) before doing tge update? Given this, could oclp not be designed to look for a “pre-install-kdk-dowload” instead of going out to wifi to fetch it ? In fact going further - could oclp not do this (putting it somewhere safe in user-data-space) with a “pre-update” action or now with semantic versioning matching MacOS could the same thing (download kdk but not install it, put it sonewhere safe) not happen automatically at oclp update? Presumably the ethernet drivers for older machines will also at some point be removed from MacOS updates, creating another obstacle for some. Of course we dont know at oclp update that a user will install some specific MacOS but in many cases they will.

Great video. My question though, I downloaded Sonoma 14.1 through OPLP 1.1 my MacBook Air 2014 model and everything went well. The problem starts when it goes to Lock Screen , to unlock it I have to restart the Mac as it keeps going black and not allowing me to type the password, what can I do to fix that problem

Mine freeze after the reboot with the status bar. I even can’t switch it off with on/off button holded for few seconds. Im on macbook pro 2015. My idea is to wait for the battery to die and try to boot after that. Any other solution?

Hi there! I’ve pressed option, pressed control and selected EFI and pressed enter and then it shows a progress bar with no Apple logo and stays stuck without showing the boot selector. I tried running in standard recovery mode and that doesn’t work either. Not sure what to do.

Does it matter which version of open core I have? I have 14.1.1 software and the same KDK but the patcher doesn't seem to do the patching properly for me.

always rock star

Hello Jessie, unfortunately i saw you video too late 😢. When i'm in de apple boot menu and press de control key. the icon changes, but after clicking on the efi logo the imac restarts and i do not get in the next menu as seen in your video. Any tips?

A couple of times now my working patched system has a meltdown and shows a white background and/or runs really slowly. I tried to update/reapply patches to fix the graphics drivers (thinking that is the issue) but next reboot it hangs after the login screen (progress bar just whirls). I've resorted to wiping the hard drive and starting over from the usb installer. That works for a while and then gives up. Might there be some auto update that needs disabling?

Mac 2015 with Sonoma 14.2 Installing KDK 14.2 and 14.4 manually didn't work, even resetting NVRAM. I did my research and I noticed that while doing the root patch, is not fetching any KDK thats already installed. Actually, when you install a KDK it should be placed on Library/Developer/KDKs, but that folder is not even created on my Mac. It's worth to mention that have to boot on Safe mode. Any idea?

When downloading the kdk, how do i know which build to install? theres a bunch, can u please help?

so i have to be very sure 14.1 KDK will work? my 2011 iMac 27" with Sonoma 14.3, wifi and blueteeth are broken .

My attempt at OCLP on my 21.5" 2011 iMac got all the way to "less than one minute remaining" then hung there for over 90 minutes b/f I pulled the plug. Any thoughts on this hiccup?

Hi, i just updated my iMac late 2013 to Sonoma 14.1.1 but now it has no WiFi connection and the background is just blank screen. What would be my recourse?

Is there a way to reinstall OCLP using Terminal that could prevent the system from freezing and ensure that it is recognized by the system for a proper startup?

hello, is there any chance you can help me please?. I made a really bad mistake. I panicked once I did the 14.1 Sonoma update and I thought the only way to sort it out was to try and wipe the hard drive via windows and now im trying to reinstall a copy of Sonoma via open core usb and it won't let me, how can I do this 😞

I had Ventura running on my MacBook and the Open Core Legacy Patcher said it had an update. After the update I reset the mac and it’s now stuck on the loading bar with apple logo. Will these steps shown it the video work in my case?

Every time I hold control and select EFI boot, it just sends me to a screen where the boot logo appears and the bar will go about halfway and stop. Any tips?

Hello, I’m experiencing some issues with my MacBook Pro (Early 2015, 13-inch) running Sonoma 14.3.1. Here’s what’s happening: I need to press Option + R to access the screen where I can view the EFI and SSD. To access the Sonoma Recovery, I have to press CTRL + Space. I follow the provided steps until I need to restart the system. Upon restarting, I press the Option key to view the icon. However, my MacBook only starts up to one-third of the way on the progress bar and then hangs. Unfortunately, these steps aren’t working for me. Any assistance would be greatly appreciated.

I LITERALLY LOVE Y

Crazy thing is that the very same thing happened to my fully supported MBP 16 M1 Pro…updated from 13.6.0 to 13.6.1 and boom!….bricked. You need another Mac (that I didn’t have) to revive the SMC and have the Recovery partition re-installed from another Mac with Apple Configurator open (Genius Bar stuff)….basically…wiping the old partition schema and re-initialising my Mac. Hence, you have more options on a Hackintosh and unsupported Macs rather than a fully supported Mac! That’s been too much even for an Apple fanboy like me: I’ve traded-in my Mac, got some good cash for future iPhone upgrades and now I’m finally out of this madness. Linux forever.

my brain start blame me when my MacBook stuck after update but this man save my MacBook Air thank u r guides

Thanks a lot Jessie. Cheers from Indonesia 😉🙏🏼
