Hi guys! On December 20,2022, I bought a new MacBook Pro 14 inch 1TB, because my MacBook Pro 2020 256GB has no more storage.
I have transferred all my information through migration assistant, and the only thing that was weird was the iMessages not syncing up, like the contact pictures and name was no up to date besides the messages…
What fixed my problem was adding my GMAIL email accounts, in my settings. and it synced! I hope this helps.
