Hey everyone,

I have a question. I think I once got myself into trouble because I accidentally synced my mum's contact - from her iMac - to my own iMac. Now, the contacts are not in the address book, but they are always available in Mail.app. What to do? Can I somehow erase the address book macOS uses? I'm on 10.12... Any help?

Greetings,

I think you may be seeing the auto complete list that Mail independently stores. From Mail Menu Bar: Window> Previous Recipients. Edit at will .... (?)

That's not bad, helped a lot - on the iMac.

Still having the same problems in iPhone and iPad. Can I somehow reset contacts there? It just synced all the contacts from the iMac, it seems...
