Apple just released Monterey 12.7.2, build is 21G1974.
Thanks, I did already add the kexts you mentioned, but wasn't able to make the changes to config.plist. No matter what I change in the plist, booting is broken afterwards.here are some observations:
- To boot Monterey, you need to at least include the ASPP-Override kext (see Complete your setup>Power management override).
- Make sure to also add the other basic kexts and device properties (see Complete your setup>Spoofing and enabling missing features).
- FirmwareFeatures and FirmwareFeaturesMask should only be added to PlatformNVRAM.

Thanks. It's a single 6-Core. Genuine 5,1 Mid-2012Post your new config with the required changes and I'll take a look. Also, if your Mac Pro has two processors, you'll need to make sure to add AppleMCEReporterDisabler (as mentioned in the guide).
I’ll set the VMM flag tomorrow and give it a go. Graphics card is indeed in slot #2.@crjackson2134 your config looks good. I'm really surprised your Monterey installation isn't booting. Can you confirm that if you add the VMM flag to this very config, your installation will boot. Also, just to make sure: It looks like your graphics card is installed in Slot 2. Is that right?
I’ve tried it with GopBurstMode disabled (didn’t help) I’ll try the SetTrimTimeout tomorrow as well.The only possibility I see config-wise is disabling GopBurstMode and setting SetApfsTrimTimeout to 0. These settings have caused booting issues in the past. Failing that, I would try creating a bootable Monterey installer and verify that booting it through OC with your config is possible.
Also - just to confirm - you only have one install of OpenCore?I’ll set the VMM flag tomorrow and give it a go. Graphics card is indeed in slot #2.

I’ll try each one at a time again to see what results I get.
CorrectAlso - just to confirm - you only have one install of OpenCore?
Yes, absolutely! If I could use Apple Services with the VMM flag enabled, I'd stop right here. As compared to Catalina, I like the fresher look of Monterey, but it's looking like that's not going to work for me.Can you confirm that if you add the VMM flag to this very config, your installation will boot.
These settings make no difference at all.The only possibility I see config-wise is disabling GopBurstMode and setting SetApfsTrimTimeout to 0. These settings have caused booting issues in the past.
I'm about to dive into OC for the first time
As compared to Catalina
No, I started with a fresh Mojave install on an unused drive (NVMe).Given that this is your first foray into OC, did you by any chance update a patched (dosdude1) installation of Catalina to Monterey? This can be problematic.
No, I started with a fresh Mojave install on an unused drive (NVMe).
I'm trying how to figure out how to do an OC install of Monterey on an empty drive. Is that even possible with a USB thumbdrive, order I need to make another clean install of Mojave and build there again? I don't see that as being productive really, since that's what I did to begin with.
Doing that now...First, create a USB installer from a full installer.
Okay, OC boot picker currently doesn't appear on my screen. Do I hold the esc-key as it's booting to get the OC boot-picker, or should I change some settings 1st?Boot the installer through OC by selecting it in the OC boot picker.
I'll review that section again.I would suggest adopting method 2 in the guide (see macOS) to avoid having to play with the VMM flag. Good luck!
You can do that. You can also keep ShowPicker=true and Timeout=10.Do I hold the esc-key as it's booting to get the OC boot-picker, or should I change some settings 1st?
Yes. You want those “updated” firmware features in NVRAM. And in addition to hybridization (changed board ID, which you already have), you also want SecureBootModel=Default.Currently, FirmwareFeatures has a data string entered. So leave that there and set UpdateNVRAM <true/>?
Well, this didn't workout so well. Totally unbootable drive after install. Even turning on VMM doesn't help. It's looking more & more like this isn't doable at all on my system.You can do that. You can also keep ShowPicker=true and Timeout=10.
Yes. You want those “updated” firmware features in NVRAM. And in addition to hybridization (changed board ID, which you already have), you also want SecureBootModel=Default.
Yes & no. I tried again and again. No warnings about firmware being unable to update anymore.@crjackson2134 were you able to boot the installer and proceed with the installation through reboots, though?
The firmware update notification is not normal. It indicates an OC setup problem or an unhealthy firmware chip.
Hi. Does someone use a WD Black SN770 NVMe SSD on his cMP here? I got one to replace my Samsung 970 EVO plus that seems to be disliked in Monterey. With SSN some issues seems to be disappeared, but speed measured by Blackmagic Disk Speed Test are really worse. Even I measure it in Monterey booting from SN770, even I measure it from Mojave (booted from another device). About half of the speeds measured with Samsung 970 EVO plus.
