MP 1,1-5,1 5,1 Monterey OCLP Migration Boot Loop

[monteallums]

I have installed Monterey successfully on my 5,1 using OCLP. It was quite the adventure, even thought I bricked it once. After much frustration everything is up and running great! I use the 5,1 with a Thunderbolt Apollo VIA a Titan Ridge PCI Card in a recording studio environment.

I’ve used Carbon Copy Cloner for years to make clones of all my disks. But as you know with Monterey Apple made things a lot more complicated when cloning. I’ve tried a myriad of usual apps, CCC, Super Duper, etc. and nothing is working. Yes I have tried the CCC Legacy Backup feature with no success.

I finally decided to do a fresh install of Monterey on a 1T SATA SSD. The SSD boots fine with no issues. I have tried to use the Apple Migration Assistant to migrate my apps, etc to the SSD with Monterey installed and the migration completes fine. But when I try to boot from the SSD with Monterey that I have migrated my data to I get caught in a dreadful boot loop!

It’s maddening! I saw someone on Youtube suggest doing a fresh install of Monterey using Recovery Mode. In the YT vid when the OP did the install it retained all his data. But when I did the install it erased all my data and just reinstalled Monterey? The OP was using a MacBook Pro so I have no clue why Recovery Mode would be different on a laptop than it is on my 5,1.

So my dilemma is I have yet to come up with a viable solution to backup my disks with Monterey? There’s got to be a solution. Anyone have any success cloning in Monterey? Any help and advice would be greatly appreciated. I work in IT so I am fairly computer savvy. But this one has me stumped.

Have you installed the OCLP to this 1TB SSD, and set the startup disk to the corresponding EFI partition (instead of Macintosh HD) using the option key?

Time Machine, rsync or other file-level operations all worked for me. Maybe avoid using block-level things like dd?

Could you elaborate the "boot from the SSD" part? like how/where you installed the OCLP and how did you select the startup disk.

Also add -v to NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args to see what's wrong before the reboot. Better post your /Volumes/EFI/EFI/OC/config.plist file to troubleshoot.

First, thank you for the reply! Yes, I installed OCLP to the SSD and set the startup to that EFI Partition using option key.

OCLP is installed to the newly installed Monterey 1TB SSD that I Migrated my Data to. I select that disc by holding down option on reboot.

Could you elaborate on the last part? No sure how to accomplish this:

you can also hold cmd and v when selecting your disk with OpenCore to get a verbose text.

It's the "verbose" boot argument so you can see the boot info like dmesg instead of the Apple logo.

This is achieved by editing the config.plist file which is located in your EFI partition. You will need to mount the partition first.

Okay, finally success!. I had tried the free Super Duper download with no success. But decided to give the paid app a try. It was worth a $28 gamble. And it worked! I also tried CCC but had zero success with it. Super Duper is the ticket! Well worth the $28! Thank God! I was beginning to believe there wasn't a solution. BTW, this old cheese grater is rocking fast with the Thunderbolt Titan Ridge Card! My Apollo Interface is working flawlessly! But I've got a feeling Monterey will be the end of the line for this 5,1. Time will tell. Huge kudos to the Opencore team of programmers! Please everyone, support their work! They are doing the Apple community a real service.
