We recently upgraded the OSX on one of our mac computers from 10.8 to 10.9.2. It was a clean install, we erased everything and then installed the Mavericks on it. I backed up this file "~/Library/Application Support/AddressBook/MailRecents-v4.abcdmr" as we wanted the existing autocomplete list to work with new mail on OSX Mavericks.
After setting up the apple mail on OSX mavericks, I copied that file to the same location. But, the autocomplete doesnt seem to work. It will not auto populate the list of email addresses once we start typing names in the 'To' field.
Also, this user doesnt maintain an address book and she completely relied on auto-complete feature for populating email addresses. Can you please help?
