thanks ill try it
you need to add the --applicationpath command at the end and drag the system image itself)
I had the same problem when moving from el capitan to high sierra)
should come out like this
sudo Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Monterey.app
try it maybe it will help you

This comes right from apples site:

For

Monterey:​

sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

For

Ventura:​

sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

This is all you need.. I make USB installers all the time

Has anyone knowledge of this error ‘Bad CurrentVBLDelta for display 69673216 is zero. defaulting to 60Hz’.
it ‘s causing beachballing for 30’s at a time and several repeats of this error appear in Console when beachballing occurs. Running latest Monterey with OCLP 0.5.2 on MBP 5,1 late 2008.

  • Nvidia Kepler GPU drivers
    • Beta7 dropped Nvidia Kepler support. This is affecting all stock 2012/2013 Mac models with Nvidia GPU including iMacs and MacBookPro systems, MacPro3.1/4.1/5.1 with Nvidia PCI GPU cards, and all iMac Late 2009 - Mid 2011 which have been modded with a MXM Nvidia Kepler GPU.
    • OpenCore Legacy Patcher has re-added support for these systems in v0.2.5
  • Intel HD 4000 drivers
    • Compared to macOS Big Sur, macOS Monterey has dropped support for Intel's Ivy Bridge Graphics. This means laptops with Intel HD 4000 GPUs will no longer have graphics acceleration such as the Macmini6,x, MacBookAir5,x, MacBookPro9,x and MacBookPro10,x
    • OpenCore Legacy Patcher has re-added support for these GPUs in v0.1.7

        • MacBook5,x and older
        • MacBookAir2,1 and older
        • MacBookPro7,1 and older (6,x excluded)
        • MacPro5,1 and older
    • BCM943224, BCM94331, BCM94360 and BCM943602 still function correctly with OpenCore Legacy Patcher

  • Non Apple Software (like Word) and Apple software like Maps, Photos, FinalCut, etc rely on the so called metal framework introduced back with Mojave in 2018. This is a low level and high speed interface to modern graphics cards.
    Pre 2012 Apple Macs lack of any graphics acceleration in all macOS versions since Mojave. Patching those older systems with basic OpenGL graphics support becomes more and more difficult. And to make it worse, modern apps using more and more metal features. So expect even a patched old Mac will not be able to run this software without loss of partial or full functionality. This problem cannot be solved or patched.
    Some Macs can be upgraded with metal dGPU, all modular systems like the MacPro3,1 -4,1 -5,1 and iMacs built in 2009-2011.
  • AppleTV and watching 4K Netflix with Safari needs either a metal iGPU (Intel CPU 2012+) or a 2017+ dGPU.
  • AirDrop, HandOff, Continuity needs a BCM94360CD Bluetooth 4.0/WiFi N combo card available since 2013/2014 in Apple Macs. Some Macs can be upgraded with those modules.
  • SideCar needs Bluetooth 4.0/WiFi N and an metal iGPU or 2017+ dGPU
  • Universal Control needs Bluetooth 4.0/WiFi N for wireless

All hardware still supported with Big Sur but dropped from Monterey support will get Apple software and firmware updates until late summer 2023. To apply those (valuable and often necessary firmware) updates you need to install and update Big Sur on your system. All firmware upgrades are bundled into the macOS updates.

The most easy way to achieve this is having an APFS container (aka volume) in parallel with your new Monterey installation. No user data needs to be copied in there. Just boot Big Sur when you get an Big Sur update notification and apply all updates.

You may drop (delete) this basic Big Sur installation after Apple stopped delivering new updates. You will not get new firmware releases.

Another method to update the firmware has been described on this site. It requires some system admin technical skills.

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 prepare my Mac?
A:
Install the latest firmware release you can get for your Mac. All system pre 2012 do not receive any new updates. Install the lastest High Sierra or El Capitan (pre 2009) version to force your old Mac to get the firmware update.
All Macs 2012+ may still receive updates with Catalina until Summer 2022 and Big Sur until 2023. The most easy way to get this still upcoming updates is having a small Catalina/Big Sur installation on a separate APFS container on the internal disk and update this installation on a regular basis.

Q: How do I download macOS Monterey?
A:
One way is to use tools such as gibMacOS which can download macOS Monterey InstallAssistant packages directly from Apple. The latest version of the OCLP tools included a download functionality and can build an USB installer automatically.

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. The latest OCLP version can download and build an installer.

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 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 we recommend joining the OpenCore Patcher Paradise Discord.
Q: How can I update my unsupported macOS Monterey installation?
A:
Just use the standard apple software update as on supported system. But is is a good practice to update OCLP in advance. Check the OCLP docs how to do this and check out the change log of the new OCLP releases. Keep in mind most systems will need post install patching after each macOS update!

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.
Trying to install Monterrey (and previously Big Sur with same issue) and get stuck once in recovery mode - unresponsive mouse…. Any insight?

When using CCC for migration I was always successful with this opposite order:
- start with an erased APFS system
- migrate the desired data to it using CCC
- then install macOS with OCLP (and possibly post-installation system patches).
Actually I found this more reliable then using the Migration Assistant proper at the end of macOS installation, i.e. during setup. Using MA even later, i.e. after setup finished and being logged in after that, often (always?) failed in my case.
Thank you very much for posting this information. I was running into the same problem, but by following your steps, everything works fine, now.

I start with formating as HFS+... Its works great as well. When you install the OS it changes the Drive to APFS

Hi guys!
I have a Macbook Pro Unibody 2012. Previously, I put Big Sur on it without any problems.
I try to install Ventura, but during the installation process the message "an error occurred preparing the software update" appears. How to solve this problem?

1. Go to the thread, that deals with the OS you're trying to install. 😇
2. Search for the error message you got. Or click here: #2,567 😇
3. Since there wasn't really any other option (and I had a backup ready), I just restarted and found the installer still as an option in the OC bootlicker. I chose it and the process continued. One more error on my MPB 10,2, but the third attempt went well. The MBP 9,1 caused "only" one error.

Hello elder MacBook Pro users!

Can I install OCLP Monterey on a freshly erased external APFS formatted ssd drive?
Or do I need another OS like high Sierra installed first?
I did this 4 times last year but on a internal drive and do not want to waste time today, now.

thanks in advance, Oh, through a 2012 MacBook Pro

Question for the experts.
Got my mac on Monterey using OCLP v0.5.3. Struggling to get another card working (unflashed ASUS GT 730 2GB DDR5, GT730-4H-SL-2GD5). Plugged it into another PCI slot while running the OCLP installer. It's Kepler v2, no? Why won't it work? Didn't see it on the list.

Thoughts?

Successful upgrade installation from Catalina to patched Monterey on my iMac 14,1. Currently using OCLP 0.4.11 for Monterey stability per @ASentientNeon. Was given 12.6.3 via the patcher, am not being served 12.6.4 as an inline update option. Everything else appears buttery smooth and stable. (EDIT: No idea why I believed 12.6.4 was out there.)

Does anyone know which patcher version of OCLP works best? I have an early 2009 iMac (9,1) which is supported. I recently did install Montery over High Sierra (update) to test it out and it worked. However, upon trying a clean install, it didn't work despite creating the install file using different versions of Open Core Legacy Patcher. On the file created with version 0.3.0, the installation hangs on "Waiting For Remote Debugger Connection" before reaching Recovery. On the file created with 0.5.3, the installation breaks at the 12 minute mark with a loading update error (An error occurred loading the update). I have spend 3 full days trying to figure out the problem but i can't.

Any idea why this is happening?

Any feedback will be much appreciated...

I remember way back that I never got Monterey to install without a metal Card on my Mac Pro 2012 but on my Mac Book Pro with no metal card It installs fine.. I just did it 2 days ago with oclp v0.5.3

I tried again with no luck but this time round, i used a USB3.0 disk which was way faster in creating the file. It installed past the previous errors and got stuck trying to download the update files at the end and then you can't do much coz the only option you get is Target Disk Mode.
At it once more, removed the Disk, clean wiped and formatted it with Paragon Disk Manager on my laptop and will try version 4.1.1 and 0.4.7 of OCLP.

Will see after restoring the Recovery partition what happens!

You seem to experience success with upgrade install over HS.

Then why not do a 2-step?

1. Install native HS; do a very basic setup from clean install.

2. Upgrade to Monterey w/ OCLP. You can resume setup to get back all normal apps/files/data.


Edit: Personally, I have no issues when I did clean install Monterey to a 2010 MBP.

Hello all.

I have an iMac 8.1. It currently runs El Capitan with all the latest updates. I have downloaded and installed OCLP 0.5.3, installed it and built the EFI and also booted into the EFI using the boot picker no problem.

I have downloaded a full version of macOS Monterey and go to install it. The installer opens and I accept the license agreement. Upon selecting what Disk to install Monterey to, it’s greyed out and a message says “this update cannot be installed on this computer”. My disk is formatted to macOS extended journaled. Some advice would be great as I can’t find any reference to this error on Dortania’s site.

I have an iMac 8.1. It currently runs El Capitan with all the latest updates. I have downloaded and installed OCLP 0.5.3, installed it and built the EFI and also booted into the EFI using the boot picker no problem.

I have downloaded a full version of macOS Monterey and go to install it. The installer opens and I accept the license agreement. Upon selecting what Disk to install Monterey to, it’s greyed out and a message says “this update cannot be installed on this computer”. My disk is formatted to macOS extended journaled. Some advice would be great as I can’t find any reference to this error on Dortania’s site.
You didn't mention anything about booting from a flash drive made via OCLP. It sounds like you're trying to run the Monterey installer locally (?).

Hi, I haven’t used a flash drive at all. I just downloaded it directly from Apple locally onto my hard drive and then double click the “Install macOS Monterey.app” in the applications folder and do it that way. It loads and accept the license agreement and then fails on the “select hard disk” where to install.

Do I need to create a Monterey USB installer with OCLP and install that way? Other unsupported systems I’ve installed Monterey and Ventura on have been newer mind you, this one being 2008 is maybe different?

Your problem stems from this; "My disk is formatted to macOS extended journaled".
Monterey requires the use of APFS. The easiest way to switch over to that file system is to download Carbon Copy Cloner, you can use it free for a month on the trial system, and make a backup of your disk to an external USB drive. You do not need a bootable backup. Use the OCLP app to make a Monterey USB install disk, and be sure to have the OCLP write to the USB's EFI disk. Boot up from that USB drive using the boot picker (option key at boot), and erase the internal disk using APFS. Then run the OS install from the USB. You can use that CCC backup disk at the end of the installation to migrate your data. Read the OCLP instructions! https://dortania.github.io/OpenCore-Legacy-Patcher/
You must run the post install Root Patches on that old hardware. After you have made sure that the system works, install OCLP to the Monterey disk so you do not need to boot from the USB drive. Getting used to using the OCLP app is essential. Good luck!
