After updating the OpenCore Patcher from 2.2 to 2.3, I rebooted my iMac and it got stuck on the Apple Logo. I have no idea what I did wrong (I can only imagine having selected the wrong disk to update).

Any steps I can take to revive my Mac?

I'm now preparing a USB-stick with the latest Sequoia installer, hoping that will fix the issue.

A couple years ago, I resurrected an old MBP 2011 with a failing Radeon GPU by applying a well-known EFI mod that bypasses the Radeon and forces it to always use the onboard Intel GPU. I also did a couple logic board mods, as recommended (removed resistor, added jumper). Worked great.

I'd like to try using OCLP to update the OS to Monterey or Ventura, but I'm concerned that it may not work on this particular machine. From what I understand, OCLP doesn't modify the stock EFI. Rather, it uses its own custom boot manager to act as middleware between the EFI and the OS.

Any advice? I certainly don't want to risk bricking this machine.

Thanks.

Trying to encrypt SSD but not working on 2017 iMac and 2015 MBP (Sequoia latest update). I get to the point where it asks me to use icloud account or generate a Text-password and I'm trying to use iCloud. However I always end up getting "error occurred try again later." I don't have any non OCLP Macs to test this on so I'm not sure if this is an iCloud issue, OCLP issue or something else. Anyone run into this issue? I could do a Text based key...but I worry I'll lose it.

Good day, I would like to ask, I installed MacOS Sequoia using OpenCore on a MacBook Pro 15” 2015, and everything works as expected, however, I cannot boot Windows from an external SSD after installing MacOS Sequoia. Using the “Alt” (option) key, I don’t see the option to select the Windows system. I can see it directly in MacOS, I try to set Windows as the boot disk, but it doesn’t work. After restarting the MacBook, it still boots MacOS. Can you help me? Thx

I have currently running my MacBook Pro 12,1 (13“ Retina early 2015) with Ventura and everything is running smooth, all hardware devices are supported. However I‘m thrilled to try Sequoia but I‘m afraid that the hardware support will be lacking. Any thoughts?

My iMac14,2 (27", late 2013) with 16GB RAM, 1TB SSD currently runs OCLP2.2.0/15.3.2) ... Now I would like to upgrade to 32 GB RAM. Is/how this possible within the existing installation, or do I need to go back to Catalina, upgrade RAM and then reinstall & restore Sequoia? Any advice greatly appreciated.

I had some issues where my WiFi kept disconnecting, at first I though it was just the Mac OS kinks until I decided to install windows on a second drive on my dell latitude 5491 laptop , however I noticed that even on windows I still had the same issue where the WiFi kept disconnecting after swapping the WiFi card I noticed that it fixed the issue on windows however now when I boot into macOS and I try to launch heliport it tells me itlwm is not running , previously when I had this issue I had just updated opencore but that does not seem to be the issue here for obvious reasons, help ? Also ps funny enough the computer now boots much faster on this new WiFi card

My 256GB SSD on my hackintosh boot drive/main SSD is nearly full. I got a 512G SSD. What is the easiest way to make the 512GB SSD now my main SSD?

I have run OCLP before, going from Monterey to Ventura on my Macbook Pro Retina 2015. I upgraded the SSD, installed Monterey, then run OCLP to upgrade to Sonoma to give it a try. The install went fine, and I was running Sonoma with no problems. A day or so later, my macbook froze up so I turned it off & on again. It would not boot up. I rebooted with the OCLP USB, went into disk utility and thought I'd wipe it all and start again, but the whole drive would not show up, only a drive of about 13gb. I tried booting back into OCLP EFI, but still nothing, just a black screen. I tried going to the Mac OS installer drive, but I got the no start up disk with a question mark. I then even tried using the Monterey install USB, but Disk Utility wouldn't show the whole drive, same as last time. I feel I've now wasted a new SSD and cannot recover it. I can't find an enclosure for a decent price that fits the Mac proprietary drive to try and wipe it. Anyone got any ideas or suggestions what I can do?

I have a 2012 MBP that I had recently updated to Monterey, and its been flickering while waking up from sleep after a certain period of time, and then going back to working like normal. Other times it takes an abnormal amount of time to turn back on and I have to force it on myself by pressing the power button. Is this something that I should expect with the update or is there any way to fix it?

Hey everyone! I recently purchased Macbook Pro Mid 2012 (i5, 16Gb RAM, 2x512Gb SSD). I moved from Air M1 to this Macbook and made TM backup. I've read on Reddit that I can't use Sonoma backup on older versions of MacOS, so I used OCLP to install Sonoma on this machine and transfered profile, files, settings and passwords to this Macbook. The thing is... The graphics and performance are kinda bad and some apps are crashing (I know it was mentioned on website, but I didn't think it was that disturbing). So I thought that maybe I need to downgrade to Monterey or Ventura to have better performance and system stability. But how can I transfer all of that to older MacOS? And will it work better on older OS or I'm wrong?

I've got Sequoia running fine on my 2017 iMac, very happy with it. However, when I turn it on it pauses on that harddrive logo at startup for around 5-10 seconds. Is there any way I can get rid of this?

A few years ago I managed to get an x1 nvidia gpu working with ventura and OCLP but for the life of me can't remember what gpu it was (maybe GT710). I just need gfx acceleration to work so is there a recommended GPU i should buy what will work with Sonoma/Sequoia and OCLP?

hay alguna manera de desactivar el turbo boost en mi mac mini 2012, no me gusta usar la app de tubo boost switcher ya que cada vez que uso la compu tengo que introducir mi contraseña y desactivarlo. hay alguna alternativa permanente? estoy en macos Monterey

I got help from here when I was installing Ventura on my Pro earlier this month, so I figured I should return an input. After installing, my macbook with 8 GB of RAM and 2.7 GHz Intel Core i5 got too slow, although it could now install many softwares that only supported newer mac os's. I tried booting in safe mode, resetting NVMe, etc., but the Activity Monitor showed that WindowServer was using too much CPU whatever I do. So I just erased the disk again and installed High Ventura (OS 10.13) via internet recovery. Now, it's fast and I am only installing softwares that support my OS. I'm much happier about it than when I had Ventura. I might have done something wrong but I failed to debug and I could not stand the slow-down. Hope this helps anyone who is looking to use OpenCore Legacy Patcher to install later OS's.

Which is better macos big sur or macos Monterey on MAC MINI MID 2011 WITH 8GB RAM, INTEL HD GRAPHICS 3000 512 MB,1TB SSD?? PLEASE TELL ME PERFORMANCE WISE???

I'm trying to install macOS Sonoma on an unsupported MacBook using OpenCore. Everything seemed to be going fine during the installation, but when the progress bar reached the end, the screen went black for a moment, then came back, and the Mac restarted itself.

Now, every time it reboots, the progress bar moves just a tiny bit before freezing. If I force a restart, I get an error message on the screen.

Do you have any idea what might be causing this issue?

I can't find any recent info on what cpus are possible to upgrade with. In 6-7 year old posts there are talks about attempting to get ivy bridge cpus to work, and I find a very generic looking page dated in 2025 claiming ivy bridge is working, but it looks very "generated" and with no sources. Supposedly there needs to be changes done to nvram to support ivy bridge, and that was what was being attempted to do many years back. Is it still sandy bridge only, or did anyone crack the ivy bridge problem? Does OCLP address this issue in any way?

I can’t seem to find it.

Any suggestions?

Hi! I've updated my late-2015 iMac OS from High Sierra to Monterey, but it's been stuck on 'Less than a minute remaining..." for 12 hours. Do you know if this is normal? Any suggestions on how to move on?

Thanks

I have a mid 2012 MacBook pro running 15.0 via oclp Computer had major issues so i ported my ram, hard disk and motherboard onto a donor MBP( same mid 2012) however now laptop is super slow and laggy Im thinking of updating to 15.3.2, however, i do not know if this will solve my issue What do you guys think?

I am trying to download macOS Sonoma on my 2015 Macbook Air. I’ve gotten to the boot screen where I can begin to install MacOS Sonoma, and it lets me agree to the terms and then it begins installing. However, when the progress bar reaches 10 minutes left, the screen goes black and I am sent back to the boot screen, where if I try it all over again, it just does the same thing. How do I install it fully and fix this? Nowhere online has given any advice that has helped so far

So I purchased the OWC kit to upgrade my iMac with a new internal SSD my question for the group is should I take it a step further and upgrade the ram as well since I’m going to have the case open anyways if so, does anybody have recommendations for which ram I should purchase? I think I have eight gigs right now, whatever came factory installed.

I just got this 17" MacBook Pro with the high res anti-glare display. It's replacing my 2013" 15" retina MacBook Pro for sure. I opted for a 2010 because I don't feel like dealing with the ATI time bomb in 2011 models, and the GT330M significantly out preforms the HD Graphics 3000 that I would've been left with.

I'm running Sequoia on it, and so far so good, gonna test chrome and proctorio, etc, but I'm sure it'll have the same issues that other non-metal Macs have...

Big Sur uniquely runs perfectly on my non-metal Macs; save for some anomalies with chrome browser.

Is Monterey similar in that regard? What are you guys running on your 2010 17"'s?

Hello... I don't know if anyone here is up for this, but I'm at the end of my rope. I have a Mid 2012 Mac Book Pro that has stopped updating past Catalina and it's unable to run Chrome. I one use this for the internet and websites are hit and miss - some will load, some won't.

I don't want to get rid of this computer! I love it! I don't want a new one and it annoys me that I would have to buy a new laptop just for the internet. That's silly. It runs perfectly well otherwise.

Can some nice person please direct me to the basics of updating this to a newer iOS? I tried digging through the sub, but y'all are light years ahead of me in terms of computer know-how and I couldn't find a post about how to start the process. I'm not super computer savvy, BUT I am spiteful enough that I will give it my best shot.

Any advice would be greatly appreciated. Thank you!

Hi all, looking to buy a 2016 Macbook Pro since I have some programs i need to use that only work with Windows. I read that Windows only uses the dGPU so temperatures are always hot no matter what you do. I'd like to enable the iGPU / dual gpu functionality in Windows and someone said if you use Opencore Legacy it will work.

Can anyone confirm this is possible? In Windows I need to use the iGPU 90% of the time, and the dGPU maybe 10% of the time. I have an old Dell Precision and this works perfectly, windows uses iGPU and some apps can use dGPU

I'm currently running macOS Ventura on i7-7500U, Intel HD 620 using OpenCore. My SMBIOS is set to MacBookPro14,1. I’d like to update to macOS Sequoia, but I’m not sure how to do it correctly. Any advice on the process?

i am having trouble getting macOS ventura to run on my msi katana 15 after i had created an efi that should have worked, but did not. the error that i had got was "OCB: LoadImage failed - Unsuported" and when i tried a prebuilt EFI for my CPU, it installed, but kept rebooting every time the loading bar got halfway. my efi that i made is here and the logs here

the cpu is a raptor lake-h cpu

This has never been a problem, and it only recently started happening after I wiped my mac for a fresh install. I have a late 2013 mac, I tried this with Monterey before hand and it said the same thing.

I followed the site in attempt to install OpenCore on My 2013 Mac Pro for Sonoma. But I failed it twice. It always comes back with a circle with cross, and that’s it for the OS boot.

I suspect I didn’t install the patcher properly. I need a quick tip instruction outlining the steps to be more clear.

Can someone please help?

Thanks
