Mid 2012 MacBook Pro Sequoia

Was having some random graphic issues today, squares of missing colors and logos just transparent, so went to update root patches and it said I was good. So I clicked on build and install opencore and let it do its thing, typically when I run into issues with laggy running or graphics stuff this fixes it. Well, now I’m stuck in a boot loop and I don’t know how to get out of it.

I’ve tried booting into recovery mode and do an internet recovery but says no internet, even with Ethernet plugged in. Tried booting in safe mode with no luck, reset nvram and SMC. At a complete loss here on what to do, this is my only computer and has all of our data on it. I do have an older back up from a year or two ago but that’s a lot of stuff lost.

I do not know what to do

My MacBook Pro mid 2010 it’s screen suddenly shuts down and he restarts I thought that would be the macOS I removed it and installed the latest supported macOS and it still restarts then I thought of the rams I changed the ram modules and still it restarts by itself but when I am at the login page it doesn’t restart and when I login and lunch safari or Google Chrome it restarts

I have 2 partitions on my mac, one for monterey (native) and other for sequoia (oclp), the "show opencore boot picker" option is checked but the mac is still booting directly to monterey

Bit of a noob question, but I'm not 100% familiar with how OCLP will affect this...

For my workflow I will likely need Tahoe sooner rather than later and will require macOS 27 and up as well, therefore I think the time has come in the new year to upgrade my main machine to Apple Silicon.

However, my current machine (Mac Pro 2013 running Sequoia) is backed up once a day to a external HD using Time Machine - will I be able to restore a newer Apple Silicon Mac using this backup, or will the OCLP install cause issues?

Thanks!

I’m on macOS Sequoia 15.7.3 with a MacBook Pro Retina (Mid 2015) and using OCLP 2.4.1. After a recent brew upgrade (likely including MacFUSE), I suddenly can’t log in with the correct password.

I can unlock the vault and turn it off in Recovery to be able to log in, so the password itself is correct.

Enabling the vault again afterwards makes me unable to log in, and I have to unlock/disable it via Recovery each time (tried a few times already).

I’ve tried several steps, including manually installing older versions of MacFUSE and other fixes suggested by AI to address password desync, but the problem persists.

Has anyone had FileVault stop accepting the correct password after a system or driver update (possibly related to MacFUSE)? Could this be a password desync issue, and is there a way to fix it without a full macOS reinstall?

Hi everyone,

I’m looking for advice on which operating system would be best for my iMac 27” Late 2012.

Right now I’m running macOS Sonoma using OpenCore Legacy Patcher, and it works decently, but I’m wondering if switching to Windows or Linux would give me better performance or stability.

Here are the specs:

• iMac 27” Late 2012
• Intel i5
• 24 GB RAM
• 500 GB SSD
• NVIDIA GTX 660M

I mainly use it for everyday tasks, browsing, some light productivity, and occasional tinkering. I don’t need it for heavy gaming, but I do care about smooth performance and long-term usability.

In your opinion, what would be the best choice for this machine today:

Windows, Linux, or staying on macOS with OCLP?

And if Linux, which distro would you recommend?

Thanks in advance!

Are they still in a development? Or it's already ended? Curious cuz I'm gonna install 26.2 on my hacks

my macbook model is A1708, and i’m using sierra. how do i upgrade it using OCLP?

All done and computer starts up to file folder with ? mark. Likely had snow leopard originally how can I get back up and running?

Help would be greatly appreciated!!!

Why would this be happening? I've reapplied OpenCore many times; I've booted from an OCLP USB and this has still happened; yes I've made sure I'm first selecting the OpenCore EFI on the initial boot and then selecting the installed drive.

The thing is, I have a few other MBP7,1 models and none of them have had this issue with the exact same process. So I'm both confused by that and by the fact that this is not happening either all of the time or none of the time, but seemingly I can only properly boot without that error if I first do a PRAM reset.

Edit to add: after selecting EFI > Macintosh HD > the black background with the white Apple logo and progress bar will load to about halfway, and then the prohibited symbol appears. So it's not just immediately showing that symbol.

Any ideas?

I was going to post about how tahoe is working on the new v3.0.0 nightly on my macbookpro10,2. And then it proceeded to freeze mid install.

when i install OpenCore Legacy Patcher done and reboot my monitor show no signal how to fix it
i use
intel i5 9400F
nvidia GeForce gtx 1050ti
Asrock b365 pro4
csm cant Disabled (when i Disabled my monitor show no signal but can boot to my windows )

Not ready to throw the towel just yet (although it's been multiple days of trying). It started with trying to install Sequoia 15.6.1 on my:

• iMac 27" Mid-2011 (iMac 12,2)
• 16GB RAM DDR3 1333Mhz
• NVIDIA Quadro K2000M flashed for boot screen
• OEM LCD Display
• 256GB SSD, 2TB HDD

Sequoia 15.6.1 installed just fine and I read somewhere that this version needs an additional pkg for my GPU called MetallibSupportPkg which I downloaded, and installed (matching the OS and build version) from Dortania's github. However, once I installed the post-installation patches via OCPL, the iMac gets to the login screen but freezes after the password is entered. Booting in safemode or booting having previously reverted the patches (which allows me to get past the login screen) reveals that the pc encountered a problem (and in short): Kernel panic due to division by 0 in windowsServer task traced back to the driver AppleBacklightExpert.

So far, i've tried:

• Resetting NVRAM via opencore bootloader
• Resetting SMC by powercycling
• Installed Sonoma 14.8.1 (same issue with same driver)
• Removing two sticks of RAM
• Opening the iMac and re-seating the LCD cables
• Reverting the patches and installing again (many many times)

IMPORTANT:

I did not do the GPU installation myself, nor do i know the implications of this. I just know that I do not have brightness control and the screen is always on full brightness. I also do not have any color profiles available in display settings, nor is the LCD recognized (just says "Unknown Display").

During my troubleshoot with ChatGPT, it mentioned that the display is not sending EDID which could interfere with the backlight driver not sending any data and causing a division by zero error.

Any and all help is appreciated if you've seen this issue before. My deepest thanks in advance!

hello, need some help here. i got 2 2015 retina macbook pros from an ewaste bin last week, both with the dual iris pro / radeon r9 gpu and 16gb ram. i installed MacOS Sequoia on it using OCLP, now im having a problem.

Specifically with audio, i have no bass, ZERO AT ALL. in settings and audio midi settings it shows only a 2 channel high output, no subs. thing is i know the subs work because i installed the default supported macos on the other laptop and it has bass, and then when i put sequoia on it i encountered the same issue. i had also ran the last supported macos on this macbook too and it had bass. its pointing at a firmware or driver issue.

problem is, i have tried EVERYTHING, ive tried all known fixes and nothing has worked, ive tried post root patches several times but it doesnt show any audio patches. and ive also tried the following:

NVRAM Reset
killall coreaudiod
VoodooHDA
Direct Driver injection from a supported os.
EFI Config Plist DeviceProperties Change
CorePKG Driver injection
Boot arguements
Layout ID Spoof
ALC Injection

NOTHING has worked, still no bass or 4ch output detected.

im at a loss here, i cant think of any other way to fix this, i had the same problem in ventura aswell so my only option is to downgrade to Big Sur which i really dont want to do. i also like desktop widgets and the new lock screen on Sequoia which is why i would ideally want to keep it on sequoia.

If you have anymore ideas, please feel free to help. i need it. thank you!

I own the 2020 Intel-based MacBook Pro with 4 TB ports.

This model is still supported by Tahoe. But since the next macOS version is rumoured to drop support for Intel, my MacBook will never have a chance to use OCLP.

Sadly.

• MacBook Pro (Retina, 13-inch, Mid 2014)
• 2,6 GHz Dual-Core Intel Core i5
• 8 GB 1600 MHz DDR3
• Intel Iris 1536MB
• Flash storage?

Recently got a 2012 MacBook Pro from a yard sale, and looks like the previous owner did do a factory reset on it and it booted up with Mac OS X (Mountain Lion) the App store and Safari can't connect due to the os being pretty old.

How should I proceed to get Catalina running on this?

I've encountered this bug on a 2010 13" MacBook Pro running Monterey via OCLP—after a reboot, sometimes the computer will not detect any wifi networks despite wifi being on. It's only after I go to Advanced… and delete ALL saved wifi networks that I'm able to see available wifi signals again.

Is there any way to fix this? I don't want to (and shouldn't have to) delete saved networks in order to connect to wifi.

I'm running 15.6.1 smoothly but lets say I want to go to 15.7.3.

Does it matter that there are a couple of versions in between or can I just upgrade via system settings?

I'll obvs avoid Tahoe and uncheck that in the install section.

Hi!

I installed macOS Sequoia 15.7.3 on an old 2013 Macbook Air (macbook air 6,2) using OCLP. I’d like to understand the correct update process when new minor releases come out.

What’s the recommended way to update the system on OCLP?

Should automatic security updates be left enabled?

Is it safe to install updates directly from System Settings, or is a different procedure required?

Thank you

On the above MBA with 4 GB RAM, I have High Sierra installed, a Catalina Dosdude version, and recently put Monterey on it with OCLP.

I thought everything went OK, but whenever I download a file with Firefox or Librewolf, the computer becomes (almost) unresponsive.

It won't freeze completely, the cursor still moves, but I can't click on other programs anymore to put them in the foreground (command + tab won't work either), the Dock won't change shape, the clock stays where it is even if I let the process take some minutes (i. e. the taskbar won't change), the fans go up high. I have to shut the MacBook down by holding the power button.

It's no use waiting for the file to download. Whether large or small files, the computer won't become responsive again after that file should have been downloaded.

This does NOT happen when I download the same file with Safari or Chrome Canary. So I thought it was a thing that affects all Firefox-based browsers. However, no problem downloading with Mullvad browser.

I did of course install all root patches after installing with OCLP. I even did it again just not to make sure. Nothing changed.

What could the problem be? This has never happened on any other OCLP install on other machines and I couldn't find this problem in forums.

Hi everyone, I’m really hoping someone here can help me. My father has a 2010 Mac with OpenCore Legacy Patcher, installed back in May. Without telling me, he recently updated to the latest macOS Sequoia, and now the Mac won’t accept any keyboard or mouse input. Built-in keyboard and mouse: not working External USB keyboard and mouse: not working Tried a USB hub: no luck The Mac does power on, but we’re completely stuck at this point. The biggest issue is that the Mac contains family photos with no backup. My father is 70 years old and unfortunately doesn’t really understand backups, so these files are extremely important to us. Please, if anyone has any suggestion on how to regain input control, access the data, or safely recover the files, I would be incredibly grateful. Thank you so much in advance 🙏

Hello,
I upgraded a 27-inch iMac (2010) with a GTX 780M (vBIOS mod) and attempted to run macOS Ventura. After installation, I am able to boot into the system. OpenCore then prompts me to install it on the internal drive, which completes successfully, including the root patches.

However, the system gets stuck on the boot screen when the USB installer is not connected. macOS only boots correctly when the USB drive is plugged in.

What would be the solution to this issue?

I have a late 2013 iMac 21.5 inch and I’ve been trying to download the patch to see if it will help me to keep this computer. Has anyone run into this problem and is there a way to fix it because I’m out of ideas and I’ve been trying to download different files to see if it would work.

Im running out of places to look for an answer for this, and it may not even be related to OCP but I thought I would ask.

After my last updated, both of the OS and OCP I can no longer sign into the machine from the login screen. I could after the initial update of the OS, but after updating OCP and committing the boot loader now when I get to the login screen, my password doesn't work. However, the strange issue is it does work from the recovery mode. I even used resetPassword utility to reset the password a few times, no change. I have also tried two different keyboard, both apple branded. I have also been trying to enable the virtual keyboard for the login screen with no luck there as well just in case its just some mapping issue where the keys im pressing are not what is being inputed, but I have no way to tell.

anyway, again, not sure this is an OCP issue directly but I thought this maybe a good place to ask. please let me know if you have any ideas, I would prefer not to start from scratch. TIA.
