OS X Yosemite Messages database merger

OS X Yosemite Messages database merger

Early betas of OS X Yosemite had a bug where the library of old messages wasn't migrated. Instead a new library was created and all old messages were gone.

This is what your ~/Library/Messages folder will look like if you're affected:
