Well, I have some troubles. First I did update from big sur to monterey pretty flawless and system ran ok but after minutes I’ve got black screen with fans on. Restart after restart nothing change. I did connect with external monitor and hangs gone. When I did disconnect external monitor hangs back after minute. Then I did clean install but with same problem! I confused and not sure what reason is it but seems related with some gpu issue which stock CPU’s iris pro without dedicated card. MBP 15 mid 2014 model 11.2. 
Do you think it could work on a macpro 3.1 ?? I could risk it but I wouldn't want to find myself with a blocked system
On a sidenote and just in case this is helpful to someone around here.
I always tried to get Virtualbox to work in BigSur and Monterey in regards the “kernel driver not installed (rc=-1908)” Error. Never succeeded until I stumbled across this tip:
Step 1 - Open Terminal, input
"sudo kextload -b org.virtualbox.kext.VBoxDrv"
Step 2 - Go into System Preferences->Security & Privacy
Step 3 - Unlock the security center
Step 4 - Approve the software by Oracle
Step 5 - Open Terminal, input
"sudo kextload -b org.virtualbox.kext.VBoxNetFlt"
"sudo kextload -b org.virtualbox.kext.VBoxNetAdp"
"sudo kextload -b org.virtualbox.kext.VBoxUSB"
Step 6 - Reboot!
Virtualbox and Windows11 run just fine ever since on this 9,2 MBP. I tried numerous other tips, but the ones above did in fact solve the issue in my case.

Installed macOS Monterey 12.0.1 with Open-Core 0.3.1 on my mid-2010 27" iMac (iMac 11,3) with upgraded metal-compatible GPU (GeForce GTX 780M) and I have two problems:
1) Wi-fi does not work. The computer cannot see any wireless network. (Firmware version Atheros 9280: 4.0.74.0-P2P)
2) The graphics is slow and glitchy and the dock is black. Seems like the graphics acceleration does not work even thought I have metal-capable GPU installed.
Any help? Please.

Yes, but without wi-fi, it does not connect to Github to download the kexts... Now trying to download the wifi kext from another computer and trying to install it via Hackintool and Kext Utility. I will let you know if it works.
get an Ethernet cable, or download the offline TUI so that you can apply the Post-Install Volume Patch without wifi. Use another one to download and transfer to the one in question via an external USB/SSD.
There's an offline release of OCLP https://github.com/dortania/OpenCore-Legacy-Patcher/releases/tag/0.3.1 . (Failing that, it's definitely worth having a dongle and ethernet cable around for situations like this.)
Hello. I installed Monterrey a few days ago on my iMac 14.1 and everything works perfect iguan than in Big Sur, except for an external monitor that I have connected by HDMI, which before worked perfect, but now it's like it doesn't send a signal .. I know that has been talked about before the topic but it is not clear to me. Is it a known problem or is it just me? I have installed formatting ssd and restarting NVRAM, any help? Thanks!!!
I have the same problem, see

I'll give it a try. So holding the shift key, get's you into save mode from the EFI boot?
1. Hold down Alt/option key and turn on your Mac, select the EFI then hit enter;
2. Select your macOS (Monterey in this case), tap the Shift key once, then hit enter.

You are using a USB hub to connect the HDMI, correct? There was an article about this on the front page of Mac rumors very recently. Even supported devices are having trouble connecting to HDMI with Monterey through USB hubs. For some users it’s just USB hub USB port trouble , but some are having trouble with HDMI port too… on supported devices…… This was a f#€k!ng nightmare when going from Catalina to Big Sur on a supported device, so that’s why I didn’t jump on the upgrade train immediately this time. Better to wait until the OS is more stable around 12.3ish…..

Ok, I was able to apply post-install volume patch via ethernet, however now I cannot boot into macOS. It gets stuck like 1/3 through the progress bar. (I unfortunatelly previously disabled verbose mode but maybe I could try booting from USB drive once again)
Edit: I tried booting from USB drive and it gets stuck here (see image).

Not sure the problem. Why not try the OCLP 0.3.2 nightly built TUI? Just wonder if you have Big Sur working in the same Mac? If so, you can boot up to Big Sur, download the latest OCLP 0.3.2 and build the EFI ...
A NVRAM reset may also help?
Big Sur ran like a charm with OCLP. Reseting NVRAM is a good idea; will try. If it does not work, I may try the Big Sur thing you proposed.
Or maybe - do you think it is a good idea trying to once again (re)install Monterey?
Thank you for your help!!
It would be my last choice to reinstall Monterey ?
Make sure the Post-Install Volume Patch is actually applied correctly.
Looking at the debug info, it seems the wifi is not properly patched so that it's not recognised by the system.

I tried to update my Mac Pro 5,1 running 11.6.1 to 12.0.1. I'm using Martin Lo's customised OpenCore 0.7.4 package with VMM flag set for installation. Unfortunately it didn't work. The new Monterey installation wouldn't boot and I had to restore 11.6.1 from backup.
Wow! I tried booting up with OCLP 0.3.2 and it worked! And wi-fi and graphics is back! Everything seems to be working right now...
Thank you really, really much. You helped me a lot.
