My macbook pro running OSX 10.7.3 will fire up the heavy fans even if left idle with all major apps closed. In Activity Monitor, AddressBookManager is shown as taking 110% CPU, even though I have only two address in my address book (mine and apple's) and I never open the application.

I can kill AddressBookManager from Activity Monitor, but it comes back again in a few minutes.

I still have loads of free memory, and the disk doesn't seem to be being thrashed, it's just the CPU usage. I probably wouldn't even notice if it wasn't for the fans.

Suggested from the comments, here's the accounts in my address book preferences:

As you can see, nothing there untoward.

Thanks in advance and for the help already.

Do you have iCloud enabled? – Richard Apr 21 '12 at 11:28
No. Every time I open settings it prompts me to set it up and I ignore it. :) – tenpn Apr 21 '12 at 11:31
In your address book prefs, look under Accounts. Is there anything more listed there than "on my mace" local? I'm sure there are other things address book manager does like allow the address book information to be inherited by other applications on your Mac but given that you're not actively using it I'm stumped as to why there's activity. – Richard Apr 22 '12 at 3:01
@Richard Good suggestion as I haven't actually looked in that window, but as you can see, no luck. – tenpn Apr 22 '12 at 8:52
Two years later, and I never solved this problem. It was a work laptop and I changed it for another one six months later. Haven't had the problem re-appear on the new one. – tenpn May 19 '14 at 8:30
