AddressBookManager consuming high cpu after upgrade to Sierra 10.12.1
After upgrading to MacOS Sierra 10.12.2 (the most recent version as of this posting) on a MacBook Air (13-inch, mid-2012) I am continually having a problem with the AddressBookManager process consistently consuming 90-95% of CPU in regular bursts. This causes the fan to run almost continuously and degrades OS performance to some degree (although the biggest issue is the screaming fan). I didn't have this problem on any of the previous versions of Sierra or prior MacOS versions.
After trying multiple troubleshooting options -- including rebooting the machine (only helps for a few minutes), closing all apps (AddressBookManager still runs aggressively), and manually killing the AddressBookManager process (it comes back) -- the only "fix" I've found is to stop syncing contacts from my Google account. These are the only contacts that I'm syncing to my machine, and it has undesired side effects like removing the names shown in the Messages app. As soon as I stop syncing Google contacts, AddressBookManager goes back to its quiet corner; when I start syncing the Google contacts again, AddressBookManager comes out of the corner and starts throwing tantrums.
I haven't found any postings online that are recent and have to do with this particular behavior specifically with the AddressBookManager process. Other posts reference other processes, but I'm not having problems with any of them. Anyone have ideas?
