How to restore all deleted text messages into Messages of Macbook running Mojave?

Hello drffc,

We would suggest working through these steps on how to retrieve items found at Restore items backed up with Time Machine on Mac:

1. On your Mac, open a window for the item you want to restore.

For example, to recover a file you accidentally deleted from your Documents folder, open the Documents folder.

If you’re missing an item from the desktop, you don’t need to open a window.

2. Use Launchpad to view and open apps on Mac and open Time Machine (in the Other folder). A message may appear while your Mac connects to the backup disk.

3. Use the arrows and timeline to browse the local snapshots and backups.

If you see a pulsing light to semi-dark gray tick mark, it represents a backup that’s still loading or validating on the backup disk.

4. Select one or more items you want to restore (these can include folders or your entire disk), then click Restore.

Restored items return to their original location. For example, if an item was in the Documents folder, it’s returned to the Documents folder.

Be sure to go back far enough to ensure that the messages would be there.

Have a good day.
