This thread will be dedicated to the discussion of running macOS 12.0 on unsupported Macs



At the time of writing, WWDC has wrapped up and Developer Seeds have been sent out. We're eagerly awaiting for all our community developers and enthusiasts to test out the new version of macOS

We will be expanding this thread with much more information as the day goes by including known issues as well as patcher support

    • OpenCore Legacy Patcher has re-added support for these GPUs in v0.1.7

    • BCM943224, BCM94331, BCM94360 and BCM943602 still function correctly with OpenCore Legacy Patcher

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.

VersionBuildLinkMirror
12.0 Beta 121A5248pInstallAssistant (Direct)InstallAssistant (archive.org)
12.0 Beta 221A5268hInstallAssistant (Direct)InstallAssistant (archive.org)
12.0 Beta 321A5284eInstallAssistant (Direct)InstallAssistant (archive.org)
12.0 Beta 421A5294gNot available currently Not available currently

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.

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 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 unsupported GPU
A:
Currently the only unsupported GPU that could regain acceleration is with Intel's HD4000 iGPUs via OpenCore Legacy Patcher. Legacy OpenGL cards (ie. non-Metal) currently have no acceleration at all in Monterey. Please stay on macOS Big Sur or older until acceleration has been achieved. For users who wish to install the HD4000 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:
With macOS Monterey, there is no working legacy acceleration patch sets. As of right now, only basic framebuffer and brightness control may be achieved, however proper animations and hardware acceleration is not available.

Understand no one can predict when there will be patch sets ready. 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 acceleration support in Monterey until next year at the minimum.

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.

What about 2013/2014 MacBooks Airs and Pros with Intel Integrated graphics?
No MBAs or MBPs before 2015, think as generous as they have been with iOS and iPad OS they've been quite harsh with Monterey, especially given Big Sur dropped a lot of macs last year too. OTOH I can see they probably want to move forward quite quickly due to the complexity of the situation?

yeah they want to drop intel macs ASAP. We have seen this before with PPC->Intel transition
