My Address Book went from over 2,000 entries to 347. Then last week it appeared with over 68,000 entries, of course, so many of them being duplicates. I am trying to clean up so I can then sync my iPhone and iPad.
It had happened with the 10.6.6 upgrade as well. Thankfully I had a recent backup/archive of my AB, so I was able to start over. A lot changed for me since then and I am looking to ensure I have no problems.
Any suggestions as to how this can be avoided in the future will be greatly appreciated.
