Q: How does iMessage sync conversation history across devices?
I am running El Capitan (upgraded a week ago from Yosemite) on my Mac laptop and running iOS 9.3.5 on my iphone 5s.
I recently turned on iMessage on the laptop and set up the contacts to sync from my iphone to my laptop via iCloud. I am seeing the contact names properly and all messages that I am sending/receiving from my iphone or laptop are properly showing up the the other device. So it appears to working properly now.
I am also seeing some of the history of conversations, but for some reason, I am not seeing on the laptop any conversations or parts of conversations after 7/31/16 which are stored on my iphone. There are also parts of conversations missings from before then although it is clear from the iphone history that they were sent via iMessage.
I have not found solutions that would sync all of the history, most recent and older. But this brings up the question - how does iMessage actually do this sync? What source of imessage history does it use for the syncing? Why would there be such temporal gaps for whole conversations as well as for within conversations?
Answers to the above questions might make it easier to solve the problem or determine that it is not solvable.
Thanks.
Mac Pro, OS X El Capitan (10.11.6)
