macOS 12 Monterey on Unsupported Macs Thread

Status
The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. Your edits will be public.
Macmini6,2 (2012 model with quad-core i7), 16GB RAM.

Followed the steps in the instructions. Using a 32GB SD card. Downloaded Monterey v12.0.1 installer; did "createinstallmedia" to the SD card; built OpenCore; installed OpenCore to the SD card; rebooted Mac, holding down the Option key; in native boot-picker, select "EFI boot" and proceed; get to OpenCore boot-picker, select "Install macOS Monterey" and proceed. Startup begins, progress bar gets to about 30%, and suddenly I slam into the "[Prohibited] support.apple.com/mac/startup/" screen. Can go no further; can only force-restart. Repeated attempts yield the same result. What's going on? Thanks.

EDIT 1: Tried the same procedure on a Macmini5,1 (2011 model); got exactly the same result.

— — — — —

EDIT 2: Back on the 2012, I rebooted and cleared NVRAM (Cmd+Opt+P+R) immediately before booting as described above. This time, I didn't get the "[Prohibited]" screen, but once the progress bar advanced to around 50%, it got stuck there indefinitely (for hours).

— — — — —

EDIT 3: I eventually got the install to work on the 2012 Mini. Whenever boot would freeze or stall, I would force-restart and just let it go without further intervention. After three or four cycles of this, somehow it worked. Freakin' bizarre, but all is peachy now. (At least on the 2012; the 2011 is still a hard "no".)

The Black A1181 Frankenbook Lives again....

A Sucsesfull OCLP install to a A1181 5.2 MacBook

I really do have better things to be doing, but it is now running Monterey with a MacBook 5.2 2.13Ghz logicboard and a ac WiFi and BT 4.0 from a BCM94360CS2 WiFi upgrade along with an SSD.

It froze 3 times on the progress bar each time I waited an hr then rebooted and it finally installed !

Actually surprisingly usable will quite happily play a YouTube video or browse the web, and idles with not a lot of fan noise !

Not working is right clicking but I know there's a Prefpane to fix that somewhere no backlight control and the function keys don’t work with their shortcuts…. everything else including airdrop etc works great.

So much for Apples planned obsolescence, a perfectly capable machine for simple necessities….. and they look so much better in black.

hi, did you get an error while installing? after i pass the language select on install process i always get an error. made the usb 3 times...

After rebooting several times, the only downside I've noticed is that boot times have more than doubled from Big Sur.

On Big Sur my boot time was around one minute.
On Monterey, I just clocked it at 3 minutes 40 seconds.

I tried to look at verbose mode, but I didn't notice any warnings or errors at the pinch points, though I may not know what to look for.

In any case, once the system does boot up, it's fast and responsive (even more so than Big Sur).
I'll just need to turn the system on in the morning before I make breakfast ?

I'm using Monterey since beta1 on a Retina late 2013 (2TB NVME) and i got no issues at all. Except that strange behaviour when booting into Sierra to make a backup of the Monterey partition (using dd in Terminal) and rebooting into Monterey, it takes 3-4 minutes to boot. But if i first boot into the Monterey installer after the backup to check Monterey's filesystem using Diskutility, it boots in about 30-45 seconds. So i would check the filesystem using the Monterey installer/recovery, maybe it's the same kind of strange thing.

Edit: Since it takes longer to boot into Sierra, i disabled automount of my APFS partitions using /etc/fstab (which is also kind of strange).

Honestly I can’t remember I’m sure it black screened and got stuck a few times and I just restarted ….
 
Before attempting patching on an unpatched unsupported Mac, booting onto any macOS Recovery on the Mac and entering csrutil disable in the Terminal and confirming the command executed csrutil status s/b now false. Clears up a lot of issues in advance, yall. :cool:

Yesterday, did a clean install on my late 2013 MBP 15". Had an issue with the final step after installing Monterey (progress bar stalling), but found a solution on a website. So far everything is running fine.

Thanks. I've never used recovery to check the file system before, is it similar to using Disk Utility in the normal system?
I'm a bit squeamish about screwing something up in my ignorance since I'm terribly new at this.
 
for those with problems with hd3000 the same in real macbook or hackintosh with these kexts and framework you can get 80 percent acceleration just running the script and installing all the kexts together is something to solve

I'd like to call everyone's attention to the fact that, as of Dec 1, macOS Monterey v12.0.1 now appears as one of the available installers to download by way of the "installinstallmacos" tool…

Code: 
[ ! -d ~/macOS-installer/ ] && mkdir ~/macOS-installer; cd ~/macOS-installer; [ ! -f ~/macOS-installer/installinstallmacos.py ] && curl -O https://raw.githubusercontent.com/munki/macadmin-scripts/main/installinstallmacos.py ; sudo python installinstallmacos.py

…which yields the following list of options (with minor variations):

Code:

Choose a product to download (1-17):

So with OpenCore Legacy Patcher, you can now install Monterey directly (it usually appears as option 4 or 5), rather than needing to install Big Sur first and then upgrading from there.

Just ran First Aid on the entire disk without any change; boot still takes around 4 minutes. It's so strange.
When the system reaches the login screen it's perfectly fine, no lag or anything, just the boot up is excruciatingly slow.

This must be used together the post patches in OCLP? Thanks.

I have tried but it´s really confusing the instructions.

Sure. I was following the Monterey installation steps from this website: https://jensd.be/1589/apple/install-macos-monterey-on-unsupported-models, but as mentioned got stuck. After installation I heard the voice over even though I was still in the startup screen. So, started up in safe mode, was able to boot into Monterey and ran the patcher, but that didn’t do it. On the website I started to scroll down to see if there was a comment section and even a mention about the problem I ran into. There was! All I needed to do was to copy OCLP to the USB stick and ran the patcher from there. Reboot and problem solved. Hope this helps anybody.

You only run the script you select option A then identify your partition monterey exemplo disk2s5 then return select option B install franework do not install privateframwork do not install kexts if you select all the kexts and let it install rebuild kernelcahe then reboot

gibMacOS-master is far more expansive and builds earlier macOS installers if necessary. However, the script works fine but there is a better way? :rolleyes:
