macOS 12 Monterey on Unsupported Macs Thread

Why not a final release?
First make a backup with Time Machine;So, without looking at all the latest messages; considering all factors such as HD4000 graphics card compatibility, among other drivers on an unsupported machine; if I'm running Big Sur 11.6.1 perfectly fine, is there any reason to switch my unsupported mid 2012 A1278 Macbook Pro with 16gb RAM, a 500gb SSD drive and HD4000 graphics card to macOS Monterey? Every-time I've gone to install the post volume patch so far, it says my machine doesn't require it. I know Apple dropped support for the HD4000 graphics card in Monterey, but has there been a fix for that that makes the entire OS worth upgrading to? My concern is only that I have everything "configured"just the way I want, and if I were to install Monterey and didn't like it, the only way I know to downgrade is to wipe my OS from Recovery mode and reinstall the OS. Or, Is this where a Time Machine Backup would come into play?
macOS Monterey requires disabled SIP and post volume patch
(post volume patch only macOS Monterey)
Yes, it is much smoother than Big Sur in all aspects, yes it is worth the upgrade.
MacBook Air 11" 2012 i5 1.7GHz 4GB RAM

I got my sorted after 3 failed attempts, watched this video:
When the install just hangs on the black screen with white progress bar, manually reboot. Hold Alt, Select EFi again, then The HD BUT holding shift. Boot in safe mode, it will let you log in, use opencore to install the post volume patch. Then go back to Mr Macintosh video and carry on the post installation actions. I used open core 3.1 but since updated and 3.2 has resolved some safari issues and cascading crash.
Will have to use versions of the applications prior to API Metal.
I finally was able to install Monterey on my 2011 MBP 15" (disabled dGPU and removed resistor) after a few hiccups using OPLP 0.3.1. Initially, I tried making the installer on a FW800 HDD, using a partition on it, but couldn't make it to the setup screen. Then I made one on a USB stick... got stuck on the black verbose screen, but finally got to the setup after a few tries. The install seemed to be going ok, but then got stuck. After a restart, it took some time, but it finally finished installing. Then I applied the patches.
Doesn't seem usable enough as a daily driver atm. There's some graphics artifacts in the Finder drop down menus, side bar and Safari. Vertical scrolling in Messages is slow. I can't get past the, "What's new" dialog in Maps. Clicking on "Done" doesn't advance. Widgets are wonky... can't edit them. A few other things that I can't remember. Bluetooth is working.
I'll keep an eye on things to see how it progresses, but I'll stick with my Mojave boot SSD for now I guess.
Edit: A couple other things I noticed. Utilities like Lab Tick and Macs Fan Control don't start at login, even though they're selected too.
OCLP 0.3.2 doesn't work for me. Gets stuck on the Apple logo screen.

macOS 12.1b runs way better than the early betas, even b6.

I fixed this issue and feel the need to post as it was very weird. I ran the upgrade which duplicated the drive names on boot in oc, and it just kept rebooting after 50% then back into big sur. tried lots of different installs of it.
Then I had enough and wanted to factory reset, I did an sec reset and one of the partitions (in the Mac boot loader) was called Monterey installer. I selected that it went all the way to the end of the progress bar took around 30 mins. then it had a circle with a line through. I rebooted and back in open core I only had one entry now. I ran this, it rebooted once, did it again and I was in all upgraded!
You have to enable Firewire booting in the OCLP settings in order to be able to boot Catalina or later from a Firewire drive.
The installer will then boot from the Firewire drive and you should be able to install to a non-Firewire drive - but it will refuse to install to a Firewire drive.
Thanks. Yeah I figured that that was the problem, after stumbling on the boot volume settings. First time using this, so trying to figure it out as I go along. Any idea why Monterey with OCLP 0.3.2 isn't booting for me?
Relying to tripmusic - It does that if OCLP re-installs are not made from a cold-boot in every instance.?

Is it me
or this upgrade a nosebleed:
with open cores,
trying to find the right link on that website
GUI is dGPU or vise versa
and terminal 2 spaces or you are toast?
Mojave and Catalina was strait to the point and just simply-worked!
dosdude for president!

Hmm... Command-Control-Power? I tried that and it still hangs. I tried Safe-Boot as well, but apparently the patcher fails to copy. EFI must not be present in this mode? I'm able to re-patch with 0.3.1 without a cold-boot though and when I revert to that version it boots up fine. Any other suggestions?
Edit: I sorted it

I’ve installed Monterey successfully on my iMac14,2, but the graphics looked a little funny so I did the patch system volume to fix my Nvidia Graphics card and it looked like everything patched correctly, but when I reboot it froze about on the apple logo with the loading bar for over an hour.
I tired a force reboot and it froze again on the apple logo with loading bar. So I had to reinstall Monterey. Any ideas how to fix the graphics without it freezing and make my system not bootable? Thanks for any help.

I am in the same boat. I decided not to go past 11.6.1 on either of my 2012's. You can always dual boot and try it out and see if its worth it to deal with the system patch at every update. For me the ease of OCLP and 11.x was just the auto update and its like a supported Mac. I found 11.x to be very stable and fast on both machines. Apple should have supported the 2012's one more OS. Alas, they didn't and here we are tho..So, without looking at all the latest messages; considering all factors such as HD4000 graphics card compatibility, among other drivers on an unsupported machine; if I'm running Big Sur 11.6.1 perfectly fine, is there any reason to switch my unsupported mid 2012 A1278 Macbook Pro with 16gb RAM, a 500gb SSD drive and HD4000 graphics card to macOS Monterey?

This is to invite Apple to break the Big Sur auto update arrangement for some unsupported Macs ? However Monterey has been released to the public now and we are going to see less and less for the Big Sur updates.
did you have to do anything special to get 12.1b installed.macOS 12.1b runs way better than the early betas, even b6.
I have MBP 8,1 and once 12.1b is downloaded, computer reboots starts install. reboots and gets stuck on black screen with apple logo and doesn't load.
I have attempted to download the beta twice with the same results.
running latest GitHub OCLP CLI and it appears to work fine in 12.01
I was finally able to install OCLP 0.3.2. For HD3000 Macs, you have to unpatch the the root volume first, update OC and patch again.

Doesn't seem to improve anything for me. Maps is still completely unusable. Can't advance past the first prompt for what's new. Have to Force-Quit out of it. Just noticed that YouTube videos sent through Messages plays audio, but not video.
That said, it's not all that bad and cool to tinker with a much newer OS than I've been using. Hopefully it gets better.
