AddressBookManager using 100% CPU
I solved this issue:


Export your AddressBook information if necessary.(I did not, because I have no import information in AddressBook)
Go to this directory /Users/luowensheng/Library/Application\ Support/
Delete the AddressBook directory, if there is synchronization, it may come back, do not care of that.
So, you can see the Activity monitor, does the AddressBookManager still high? if still high,  delete the AddressBook directory more times.
