If You Can't Upgrade To Monterey, Try This

I was hitting an annoying issue and it took me the whole night (went to sleep 5 AM...) to find a solution online...

I would run the Monterey installer, it would do its thing, and ask me to restart...

However once I selected the new "Macintosh HD" installer partition that was created, it would just load for a few seconds and reboot... So I was stuck on Big Sur 11.6.

I found this solution on both Tonymac and on Olarila...

You just have to edit the following settings in OpenCore's Config Plist:

  1. AllowRelocationBlock -> True;
  2. ProtectMemoryRegions -> True;
  3. SecureBootModel -> Disabled;

Save the file and unmount the EFI partition.

Clear the NVRAM, boot into your earlier macOS version, run the Monterey installer again (this cannot be skipped, you must run the installer again -- hopefully you didn't delete it as I stupidly did...)...

Now when you select the installer partition on OC's boot picker, it should run as intended.

Thanks to Shinji3rd which found this solution first!

Now running 21A5522h smoothly.

Note: It's weird that for some reason the Monterey installer that is in the "Applications" folder is not a full installer, it's just a 20MB stub. I don't know where the remaining 11+ GBs of data is stored in the disk... So I couldn't use "createinstallmedia"...
