I had that issue as well with my mid-2012 MacBook Air. Everything went fine when upgrading to Monterey via OpenCore Patcher using 0.4.3, however the keyboard backlight didn't work at all and showed blanked out in System Preferences. Rebooting fixed that. Rebooting also got rid of the 'Volume Hash Mismatch' error, so that was neat as well.

All in all, its been a pretty rock solid experience. I'm glad people are keeping these old Macs updated.
My guess it would have to do with the new way they're implementing SIP and the Root Patch.

anyone able to get Universal control working? Like between 2 Macs. I have a 5,1 Mac Pro and a 2011 iMac running the same latest beta 4 and I turned on universal control on both but the mouse won't move to the other screen.

Thanks

UC needs BT 4.0 + WiFi N on both machines. Check out either the first post or the FeatureUnlock GitHub page.

There are more and more features depending on real hardware upgrades.

P.S.
Works on all of my iMacs 2010/2011 with BT4/WiFi upgrade and 12.3.1

Yep. Iv had those upgrades for awhile. Back when handoff and continuity were released.
Iv gone over setting it up on both machines a few times now. I have to be missing something somewhere.
Thanks for the info

I’ll have to check and make sure the latest OCLP 0.4.4 has that lilu kernel extension

A little further reading and it appears I may need to spoof my 5,1 Mac Pro and my 12,2 iMac to something different. Does that sound right?
Thanks again for any help.

I've re-built OpenCore, now at 0.4.3, and Universal Control… I'm not sure. The Universal Control… button shows up, as it did before, so I'm assuming part of macOS thinks it should work? But it doesn't seem to.

(Maybe the release notes are saying "if your Mac natively supports Monterey, but not Universal Control, we're patching it to add UC". Mine doesn't natively support Monterey. But it does have Haswell…)
Just wondering if you ever figured anything out with Universal Control? I got it now where the Universal Control (3 options to checkmark) show up and I can select all 3. But under "Add Display" I can only mirror. There is no option to select keyboard and mouse.
If you have any idea that would be great

Both machines are on the latest macOS Monterey beta using OCLP 0.4.4n

Well, this doesn't perfectly fit the theme of this thread but I don't know where else to put it, and I thought it might give others a chuckle or two.

My trusty late-2014 iMac is one of the models not upgradeable to Monterey (without taking the path others here have taken, I know).

And yet, I am regularly receiving notifications to 'Upgrade to Monterey!', after which I dutifully click on the notification which takes me to Software Update which thinks about it a few seconds and then tells me 'Your Mac is up to date - macOS Big Sur 11.6.5'.

No big deal but surely Apple is capable of telling its software update programming to leave us unsupported Macs alone and not keep rubbing it in that we can't install Monterey (directly via Apple, at least)?!?!

(I keep thinking that maybe I can fool the software update into giving me Monterey if I continue to be obedient in responding to the reminders, but so far no such luck . . . )

great post!
well written, on topic-ish
oh
Apple PROBABLY has analytics on how many users buy new macs over this procedure.
My MOjave OS did the same thing today on a MBAir 2010.

I installed macOS 12.3.1 on my MacBook Pro 13-inch (MacBookPro 7,1) Mid 2010 with SSD, 16GB RAM, nVidia 320.
I would say that everything you need in daily office use works.
Faults: the Wi-Fi takes a few minutes to see the connections and I found that if I open System Information -> WiFi it unlocks immediately ...
iMovie opens and crashes when I start creating a movie; but it also happened if I installed Catalina with the dosdude1 patch. Anyone know how to fix this iMovie issue?

Here is how I installed:
- I started from macOS High Sierra
- I downloaded OCLP 0.4.4 Night Build GUI and started it
- I selected SMBIOS "Minimal", created the EFI Boot build and installed it in the internal SSD
- I restarted the Mac by pressing ALT on boot and selecting EFI Boot
- I downloaded the Monterey Installer from the App Store, started it and waited for the installation to finish.
- After Login I restarted OCLP 0.4.4 Night, applied the Post Install Patch and restarted.
Initially the Mac was running very slow, the fan was running and the screen had glitches but the transparency of the menu bar, the Dock etc are very perfect!

Everything then improved:
- after waiting for Spotlight to finish indexing e
- after restarting OCLP 0.4.4N and selecting the options to remove "non-Metal" video card artifacts.

Ah! ... Obviously, in the end, I created an EFI Boot with SMBIOS "None" option instead of "Minimal" and I preferred to use this, as suggested.

In conclusion:
is it worth installing macOS Monterey in these MBPs?
It depends on the use you want to do and if you have an SSD and a lot of RAM.
Great, for example, with Apple Photos or Affinity Photo, with Pages, Numbers and Keynote, with MS Office 365, etc.
As I said before, so far only iMovie opens but then it doesn't work.
Obviously forget about AirPlay (at least for now) but using Reflector 4 or other AirPlay substitutes it works, albeit with some video glitches at the edge of the window.

Both machines are on the latest macOS Monterey beta using OCLP 0.4.4n

It did eventually work for me, but not entirely reliably. I think it simply took a while (a minute or two) until both Sidecar and UC showed up.

(My main problem was something entirely different: my user account is in a different Apple ID. I had to switch to a use account that matches the iPad's Apple ID.)

(edit) Just to clarify, I think the reliability issues have nothing to do with OCLP and are simply because UC is still in beta, and/or because all those Continuity features have a habit of only working ~80% of the time.

OCLP 0.4.4 and manually disabling TRIM (SetApfsTrimTimeout=0) fixed my boot issues. There's an issue with Samsung NVMe drives.

OCLP 0.4.4 links are here:
Can someone please assist on how to disable TRIM using OCLP. I downloaded v0.4.4 but I don't see the "SetApfsTrimTimeout" anywhere in the settings. I've also tried the sudo trimforce disable command but it doesn't work since moving over to OCLP. TRIM is definitely the cause of my long boot times which is now sitting at almost 20 minutes: kernel: (apfs) spaceman_scan_free_blocks:3154: disk4 scan took 1124.366080 s, trims took 1124.027802 s.
 
- I selected SMBIOS "Minimal", created the EFI Boot build and installed it in the internal SSD.

from the Open Core patcher GUI menu, or from a GitHub download link?

my hurdle is formatting the USB to "EFI"
i can't "for the life of me" get beyond that step.

First, mount your EFI partition. Easier way is using this script: https://github.com/corpnewt/MountEFI

Navigate to your EFI folder and then the OC folder. Edit the config.plist file.

Modify these lines:

From:
<key>SetApfsTrimTimeout</key>
<integer>-1</integer>
To:
<key>SetApfsTrimTimeout</key>
<integer>0</integer>

Save config.plist. Reboot.

With OpenCore Legacy Patcher 0.4.4 Night, of course ...
However I want to rectify the enthusiasm of my previous post.

In the end I preferred to remove Monterey and through Time Machine I reinstalled "High Sierra" on the fly.
With Monterey, in fact, in addition to the iMovie crash, the Apple TV movies did not work and to start the Wi-Fi connection you had to open System Information -> WiFi every time (and this is a nice mystery ...)

After that, with the dosdude1 patch for Catalina, I installed Catalina and as soon as the installation is finished I will use:
- the "CatalinaOTAswufix.app" patch to update Catalina in OTA mode to the latest security update 2022-004, otherwise it is impossible to update [see: https://forums.macrumors.com/threads/macos-10-15-catalina-on-unsupported-macs.2183772/post-28320558 that include the "CatalinaOTAswufix.app" download]
- the command from Terminal to NVRAM
Code:
sudo nvram boot-args=amfi_get_out_of_my_way=0x1
to prevent repeated crashes of many applications on startup. Without this command some applications, especially those of MS Office, start and function correctly, but only after several crashes and restarts.
In the end, if iMovie doesn't work in Catalina too ... it will mean that I will resign myself to reinstalling "High Sierra" and patience ...

My 27-inch late 2013 iMac, on the other hand, continues to work wonderfully with Monterey.
 
my failures were not clicking install on the USB, i ignored that blue lighted wand.
and now installing.
is 4GB ram enough?

4 hours plus (1hr 45 mins at "less than a minute") ha! and one cold boot towards the end and Build 21A5522h is installed,
Thanks, the MBAir 2010 is show "less than one minute"30 minutes ago, after about an hour of install.
we will be patient!

Thanks for the detailed instructions. I set it to 0 but for some reason TRIM is still occurring during boot up. Maybe OCLP or Monterey just doesn't play nice with a Western Digital SSD

Might ask over on Discord to see if someone can help. Or dig into the general OpenCore forums. My understanding is that setting it to zero should disable TRIM during boot. You sure you're running OCLP 0.4.4?

The fix didn't work for me when running 0.4.3.

This post helps explain what OC is doing. The setting only affects TRIM usage during boot.

Yes, iMovie, Final Cut Pro X and Logic Pro fully on MacBook Air/Pro 2010 GeForce 320m

Use last version non-metal
