Unfortunately, no! You cannot alter the system volume without disabling SIP. Welcome to the world of unsupported legacy Macs!
Okay! So to clarify about HD4000 acceleration, if I want to stay on Big Sur, do I need to change patch settings somewhere in OCLP 0.3.0 to disable the HD4000 acceleration root volume patch or do I use OCLP 0.1.6 instead?

I don't understand where or how OCLP does the root volume patch, so since the latest 0.3.0 is geared towards Monterey, how will it know not to patch the root volume for graphics acceleration since I'll install Big Sur after?

Hi, everyone!
Wanted to thank You all for keeping older systems up to date!
Installed Monterey (12.0.1) on a mid-2014 MacBook Pro, 13in, Retina. (Macbook Pro 11,1)
All seems fine with one minor annoyance - often (but not always) weird graphics artefacts/glitches in Finder under list view (uneven, coloured stripes; pic attached).
To recreate - with everything closed, open something using Finder from menu bar, like Finder-Go-Computer (or other folders, ex. Documents, Applications etc.)
Happens in light mode, dark mode seems unaffected. Glitch goes away while scrolling or by moving window. Also, I can't get a system screenshot, because, as soon as I press Cmd+Shift+4, glitch disappears or becomes less visible (second pic.).

Am I the only one with such glitch or did I do something wrong? And is there anything to do to get rid of this (tried NVRAM reset to no avail).

EDIT: I'm using the latest OCLP (0.3.1)

Monterey: latest OCLP and SIP disabled and post install patches required
Big Sur: latest OCLP optional, SIP can be enabled and no patches necessary (as before)
There is a section about OCLP update in the docs - please check it!

I had kept some Geekbench 5 tests results done in my cMPro 4,1>5,1 and Opencore running Mojave 10.14.6 and BigSur 11.0.2.
Today I have done the test running Monterey 12.0.1.
The scores are similar in Multi-Core and better in Single-Core

My feeling after some hours of use is Monterey runs even smoother than Big Sur in my computer.

Tonight I'm going to attempt this install on my mid-2012 15" unibody MacBook Pro. I know I'm going to use the latest patch that'll support the Intel HD Graphics 4000 chip, but anyone else have any more advice/recommendations? (I've already made a Time Machine backup of the system, just in case something goes wrong.)
 
Yes, but I don’t know what selection is necessary prior to build oclp. Do I build I oclp, run patch and restart?
You would build OC first.

Then you would install OC to your boot drive, either internal or external.

Reboot.

Run Post-install patch.

Reboot again.

if you're getting a boot loop, I suggest taking a look in Patcher settings before building. Try 4 and 5 especially as these sections deal with boot and GPU settings.

Ah so Post Install Volume Patch is what applies the root volume patch...

Are you referring to this doc?:
If not, could you provide the link please.

Sorry I've scoured the documentation and couldn't quite connect the dots on that.

Installing macOS Monterey on an unsupported Mac
Q: How do I determine what Mac model I have?
A:
To determine your Mac's SMBIOS model identifier, simply run the below command in Terminal:
Code:
system_profiler SPHardwareDataType | grep 'Model Identifier'

Q: How do I download macOS Monterey?
A:
The easiest way is to use tools such as gibMacOS which can download macOS Monterey InstallAssistant packages directly from Apple.


Q: How to create a USB installer after downloading the InstallAssistant package?
A:
Install the package, it creates an app named Install macOS Monterey in your applications folder. Create the USB installer following this official Apple guide.

Q: How can I use this installer on my unsupported Mac?
A:
Before hitting the download button of the patcher tool (see below) please check OpenCore legacy Patcher's documentation. It contains a support statement about unsupported Macs running Monterey, too.

Q: Where/how can I download a patcher tool?
A:
Currently there is only one patcher that will soon be supporting macOS 12, Monterey being OpenCore Legacy Patcher. As time goes on, we expect many more developers to join in with their own implementations of the patching process:

  1. OpenCore Legacy Patcher by @khronokernel and @dhinakg is a completely different approach compared to older patcher methods based on OpenCore. This is currently the only option offering system updates via Apple software update like all supported Macs as well as Intel HD4000 iGPU and NVIDIA Kepler acceleration. While the preparation uses a simple GUI the Monterey installation and updating happens in the same way as on supported systems via System Preferences.
    • Supports macOS 10.9, Mavericks and later to run.
      • Supports macOS 10.7, Lion and later if Python3 is installed manually.
    • For easy troubleshooting and discussion with developers, we recommend joining the OpenCore Patcher Paradise Discord.
Q: How can I enable acceleration on my newly unsupported metal GPU?
A:
Currently one can regain acceleration for both the Intel's HD4000 iGPUs and the NVIDIA Kepler dGPU via OpenCore Legacy Patcher. For users who wish to install the HD4000/Kepler acceleration patches on non-OpenCore Legacy Patcher machines see here: How to Root Patch with non-OpenCore Legacy Patcher Macs/Hackintoshes

Q: When can we expect OpenGL/non-Metal GPU Acceleration?
A:
Starting with OCLP version 0.2.5 legacy OpenGL/non-Metal acceleration for Monterey has been implemented.

Please understand no one can predict when there will be patch sets ready or if current glitches can or will ever be resolved. Remember that it took over 300 days from Big Sur's unveiling to achieve public acceleration for non-Metal GPUs. And with TeraScale 2 acceleration, this took almost 3 years to achieve public acceleration. So be patient as developers are hard at work, however expect no error free support in Monterey. Additionally most applications rely more and more on Metal GPU features. Such apps may cause just a feature loss or will completely fail on non-Metal system. This will never change and the only way out is changing the GPU (iMac Late 2009-Mid 2011 and MacPro systems) with a Metal compatible one or buying a new Mac.

Please remember it is highly suggested that you have a backup in place before installing new system software on your main devices, overwriting any stable releases.

Apple and all patch developers are not responsible for any potential damage or data loss caused by using pre-release software or unofficial support patches. Please use at your own risk.
does this tutorial work with the release build for the macbook pro retina late 2013 13"? I'm seeing a lot of things in this thread but not this information and how to properly do it. Do I just download the latest version and do everything else as posted? Thanks in advance!

Hi guys, I have an iMac 21.5 mid 2011, can it be updated to Monterey without any issue? Or do i need to update hardware (i already put an ssd inside and more ram ) ?
 
Trying to install Monterey with the latest open core and release build on a MacBook Pro 11,3 Mid 2014 15 inch...I have gotten it to install, however on boot, the machine tries to boot up, it gets to a point where the voice assistant starts talking about voice over, which signals that its at the initial setup screen, however the screen on display is still the apple logo with a stuck progress bar, I tried to hit escape and it said more voice over stuff but again its just stuck on the apple logo and loading bar, I've tried restarting to no avail...also I noticed that the text is very tiny compared to how it should normally be, I installed open core on the installer usb via open core gui, will try with there terminal version to see if I get any different results, but according to documentation everything should be natively supported by open core on a 11,3 MacBook Pro, if it doesn't work with terminal building, not sure what I could be doin wrong, only thing I can think of that I may need to change is the Metal GPU settings in open core when I goto copy/build it on the USB, my 11,3 has both a Nvidia gpu and Intel. Any help or suggestions from anyone thats used open core on a 11,3 15 inch would be much appreciated.

Advice needed for MacbookPro11,3, A1398, from you wonderful people. Failed twice at installing Monterey.
I've tried Beta10 with OCLP 3.0, and
RC2 with Nightly OCLP 3.1.
Both get to a certain point and hang at the same progress bar after rebooting a few times.

Any other combinations of beta and OCLP I should try?

I should probably mention my SSD is a Samsung NVME SSD, this is the only thing different from the original spec. I'm wondering of this would affect it?

I'm having the same issues, the interface shrinks so the text is tiny but I can't get past the third progress bar so back to Big Sur for now

Same issue on 15” Late 2013 + OC terminal ver
You need to boot to safe mode and install the post-install root volume patches for Nvidia Kepler. Power off the machine. Hold shift during boot. This should get you past the boot screen hang and to desktop. Using the OCLP TUI version, select option 3 from the main menu (the one that says "post-install root volume patch" or similar) and follow the prompts.

Edit: And keep in mind you will need to do this every update. Since it's kind of a pain in the butt, I would recommend discontinuing the beta/dev track now that Monterey is GA :) So that you don't have to do it as often.

Can you go into more detail about that? I've heard about this but I'm afraid of the 'side effects' so to speak. Is there a good installation guide for the Mac Mini and Monterey or do I just use the official docments?
I don't know any more details besides the fact, that with Monterey (unlike Big Sur) the HD4000 needs to be patched, and to make that possible SIP and SBM must be disabled. Sorry, I'm not at all an expert, all I know I got from the OCLP guide where all questions should be answered (well, reading this thread could also help ;-) )

I'd rather keep SIP enabled, but that's the price HD4000 user have to pay from now on (just like any older GPU user)
 
You would build OC first.

Then you would install OC to your boot drive, either internal or external.

Yes I have the Early 2011 MBP 15 inch with the dGPU ATI 6970M 1GB card and it still works well. I see in the settings it has a caption to turn off Terascale 2 but it states it automatically installs it. Should it say FALSE or TRUE? Its confusing.

Take a look here:

 
Upgraded my Big Sur installation via software update and OCLP 0.3.1 to Monterey on my mid-2012 cMBP.

Seems to run mostly fine, but there is something weird about the graphics, it feels like it crashes to frame buffer when the HD4000 is put under any kind of strain. The graphics parts of geekbench locked up the computer completely, forcing a hard reboot, but basically, any kind of heavy load on the gpu will randomly make it run like an unpatched system until i reboot.

Dunno, I'll run it a while, maybe do a fresh reinstall instead, but I have a feeling I'll be back to Big Sur soon. That ran beautifully, felt like a native install too.

I'm lost as well
what the helk' is going on?
i have no idea what the 2021 computer terms mean or what to click on that github.....
and i even watch Linus tech tips occasionally, mostly for entertainment tho
maybe i should pay more attention?

installing Monterey was just for fun and to see if i can
now im realizing going from Catalina to BigSur was performed by apple
yes 
who let me install BigSur via software update in September without a patch or USB drive.
but BigSur really sucked so i went back to catalina was is spinning on an 2GB MBA

somehow the whirlpool washer machine accepted Monterey and is washing those in my iclouds circle dishes.
so i guess this was no tin vain.

i needa nap!
 
Much thanks again for the magic.
Screenshots from 3 of 6 all current and working well.

Did you try to patch the HD4000 support back?
Yes, even tried the nightly (0.3.2). It has full graphics acceleration, the HD4000 is recognised correctly too.

Except when you push it, it definitely crashes back to framebuffer. Acts exactly like it does before you run the post install patches.

A reboot fixes it until the next time it happens. Its wierd. I'm gonna try a clean install tomorrow maybe something interferes with the patch since i upgraded from Big Sur, which has native HD4000 support.
