In activity monitor, AddressBookSourceSync is using between 5 and 100% of my CPU and masses of RAM. If I quit it, it comes straight back.

What is it and how can I make it go away?

You should probably read that whole discussion thread, so you're aware of potential problems others have seen, as well as other possible solutions.


Found by googling AddressBookSourceSync, clicking on the top hit (which is the Apple Discussions thread), then reading back through the thread to find the solution different posters were saying worked.
