I noticed that anything before near the beginning of this month all the way to the end of June last year is just gone. There are plenty of messages before all that, but the parts of conversations during that period simply no longer exist.
One problem is that I can't find the chat.db file, Attachments folder or other stuff in Library/Messages from shortly before that period. (I had to head to work, so I didn't get much of a chance to look at even earlier periods.)
I don't necessarily need it in iMessage format, if the SMS messages with attachments are available through an iPhone backup. I do not need the stuff to be re-inserted into iMessages necessarily and I don't want to lose the messages that have happened since the beginning of this month either; I just want be able to keep the old ones.
Normally, I'd have waited until I got home and to mess with it, but I guess I'm just a bit panicked; there's a lot of stuff that gets talked about over a year and I very much want it back.
(There is a Time Capsule, but honestly, I have never actively used it so I'm not sure how to work it.)
