I could, but if it fails, then that's a half a day wasted on a failed migration.

Hence, I asked for verification. Where did you get the information, btw?

By actual testing on more than one unsupported Mac. As @******* posts Migration Assistant functions with a fresh install, only. This can be easily confirmed. Ahem, being willing to experiment is part of the unsupp culture, tbh. And giving a native app which accesses an entire volume in a controlling mode full permissions seemed logical? 🤷‍♂️

I can't do that, because I only have ONE Mac, which I have to be sure is working after migration, hence, I have to be sure of the veracity of the information that someone has actually done it repetitively.

I've done several fresh Monterey installs then Migration, Monterey upgrade from a fresh install of Big Sur then Migration, and a Big Sur then Migration then Montereyall of which failed, which lost me a lot of time just tinkering, so, if I can avoid that with a verified solution, then by golly, I'd go for that verified, repeatable solution.

The thing about what's happening so far when it comes to OCLP and upgrading unsupported systems is that there's no consistency. So, whereas what you did worked for you and others, the same process might not work for me or others, because we all have different setups regardless of the similarities of system specs.

That's why I'm asking for verification. Otherwise, it's something I might try later, when I have time to waste to test it.

Thanks anyway.

Find someone with your exact Mac to verify? Since it works for others your issue may be OCLP machine or user specific. Verified here on three different unsupp Mac models and a fully supported Mac, as well. But not that particular MacbookPro. 🤷‍♂️

I have done it in a Macbook Pro 17" 2011, Mac Pro 4,1->5,1, Mac Pro 5,1, Mac Pro 3,1 and Mac Mini 2012.

I installed the update on my 2012 MacBook Air, and after seeing the login screen for a few seconds, the screen turned blank, and only a frozen mouse cursor is visible.

Edit: Alright, that was only a broken screen saver due to missing GPU acceleration. 🤷‍♂️

Yep, saw the same thing on my own 2012 MBA, post install patch made it normal again!

On 12.3.1 I still can't use VMware Fusion (or Parallels). VMware fails to start my VM with "error -14: Pipe connection has been broken".
This was no issue with Big Sur, and the VMware forums mention this is an issue with Intel GPUs. Is this an OCLP related issue or just some Monterey problem?
Headless VMs like with Docker Desktop still seem to work.

Hail LordDeath, I haven't updated to 12.3.1 from current 12.3 on MBP mid-2012 (9,1). I am successfully running Parallels Desktop Parallels 17.1.2.51548 without a hitch. I don't use VMWare however. I did do a clean install to 13.2.1

Me too with my 2012 Mac mini. With patches reinstalled everything is running nicely. Today I also installed the latest firmware for my machine that came with the latest Catalina update a couple of weeks ago.

MBP5,2: installed 12.3.1 over 12.3 OTA, using OCLP 0.4.3 including for post-install volume patches.
Smooth updating, result looks fine.

Can you elaborate on that, please?
Did you boot into a separate Catalina installation, or can this be done directly from Monterey? Also, how would someone check whether there is a new firmware available for a particular device?

You need an external USB drive or external SSD drive, install Catalina 10.15.7 on that. It will update the firmware on your m/c; on mine it took me from f/w version 425.0.0.0.0 up to 426.0.0.0.0

To find out what firmware you should be running on your m/c search for 'SilentKnight', read all about it, download, install and run it. Highly recommended, screenshot below.

I am on EFI 421.0.0.0.0 and a version 426.0.0.0.0 is available as well. Time to update!

If you can, try to maintain a bare bones install of the last supported macOS version for your m/c. For me, that was Catalina, I guess we're in the same boat.

That way, if a security update to Catalina hits which contains a firmware update you can install it and keep your firmware up to date. You're probably thinking it's weird I totally agree with you. But that's what I had to do, and it does work, strangely enough.

Dude, don't assume it's THAT easy for anyone or everyone. If I had access to other Macs, I wouldn't have done it already myself. I don't post or comment here if I don't have to, and when I do, it's either to confirm, verify or add information, not grovel.

Again, thank you, but, you have not added any new or useful information I do not already know.
