Backup and Restore Apple Messages on macOS

Is there some means of saving your Messages history on OS X and copying it to a new system without doing a full restore from a Time Machine back up?

Doing some searching, I found the below and tried this approach in a virtual machine copy of Mavericks without much luck.

Despite copying the files to their respective locations on the fresh install and adjusting permissions, the new installation version of Messages never seems to import/recognize the history from my current system.

To ensure my permissions were okay, I also found

Mavericks Mail will not save preferences

which was linked to by

Fixing broken Messages on OS X Mavericks

but this also did not result in Messages importing/using the copied history. Both instances of Mavericks are using Messages 8.0


Yes, it is possible to import message history from a Time Machine backup onto a new machine without a full restore from a Time Machine backup. This was tested on 10.10 but should work for at least 10.9 as well.

  1. Take a full Time Machine backup of the new system.
  2. Quit Messages.app.
  3. Remove all of the following files and directories on the new system:
    • ~/Library/Caches/com.apple.iChat/
    • ~/Library/Containers/com.apple.iChat/
    • ~/Library/Messages/
    • ~/Library/Preferences/com.apple.imessage.bag.plist ~/Library/Preferences/com.apple.imservice.FaceTime.plist ~/Library/Preferences/com.apple.imservice.iMessage.plist ~/Library/Preferences/com.apple.imservice.ids.FaceTime.plist ~/Library/Preferences/com.apple.imservice.ids.iMessage.plist ~/Library/Preferences/com.apple.iChat.AIM.plist ~/Library/Preferences/com.apple.iChat.Jabber.plist ~/Library/Preferences/com.apple.iChat.LSSharedFileList.plist ~/Library/Preferences/com.apple.iChat.StatusMessages.plist ~/Library/Preferences/com.apple.iChat.Yahoo.plist ~/Library/Preferences/com.apple.iChat.plist
  4. Copy the following files and directories from your Time Machine backup to their respective locations on your new system:
    • ~/Library/Containers/com.apple.iChat/
    • ~/Library/Messages/
    • ~/Library/Preferences/com.apple.imessage.bag.plist ~/Library/Preferences/com.apple.imservice.FaceTime.plist ~/Library/Preferences/com.apple.imservice.iMessage.plist ~/Library/Preferences/com.apple.imservice.ids.FaceTime.plist ~/Library/Preferences/com.apple.imservice.ids.iMessage.plist ~/Library/Preferences/com.apple.iChat.AIM.plist ~/Library/Preferences/com.apple.iChat.Jabber.plist ~/Library/Preferences/com.apple.iChat.LSSharedFileList.plist ~/Library/Preferences/com.apple.iChat.StatusMessages.plist ~/Library/Preferences/com.apple.iChat.Yahoo.plist ~/Library/Preferences/com.apple.iChat.plist
  5. Restart your system
