Does anyone know a Time Machine expert?

I just upgraded from Mojave to Monterey and I cannot see my previous backup points in Time Machine. They are all on the drive but Time Machine doesn't recognize them.


Is there any way to recover the old backup points?

Boot Mojave (installed temporarily on external storage or otherwise), and check the Time Machine backups from there.


Back in the Big Sur and Monterey era, Time Machine got updates including APFS support, and removed the backup of the system volume.


Internally, Big Sur and Monterey are very different from earlier, as well—that’s when the signed system volume was introduced.


Pragmatically, I’d retire these backups and quite possibly also the HDDs they rode in on, and start with new APFS-based backups as needed.

Thanks for the suggestion, but all those solutions have been examined and are not relevant. I'm trying to find someone who understands some of the internals of Time Machine enough to possibly suggest how to reconstitute the backup to allow time machine too work properly. All the restore points are there, but not accessible in time machine. Apple support won't even talk to me because of the age of the OS. I suspect in dog years or cowputer years its pretty old...I guess.
