The process tccd is consuming a lot of CPU

A week or so ago, I receive a new 2013 MacBook Air, to which I cloned my 2012 MacBook Air, and started using. Then I discovered a display issue, and Apple sent out a second unit, to which I cloned the defective one, and started using.

On this unit, I've noticed a continuous CPU profile that looks like this:

The process tccd frequently jumps from nothing to 50%.

Any ideas what the problem could be, and/or how I could fix this?

Thanks so much in advance!

MacBook Air, Mac OS X (10.7.4)

Ok I just solved this — The underlying problem turned out to be related to broken rules in Hazel. I documented it here:

From another Forum entry:

It looks like it is responsible for managing which applications have access to your contacts. The similarly named tccutil is a command line tool to manage your privacy database. tccd has a database file in each user's home directory ~/Library/Application Support/come.apple.TCC/TCC.db that appears to store which apps you have allowed and denied access to for your contacts.

I noticed this process using more CPU than I'd think would be necessary (5-13%), but it seemed to drop down after 10-20% minutes of being like that. Certainly seems like it might be a little buggy.

For some reason, the post indicates I'm running OS X 10.7.4, and won't allow me to change that to 10.9.1.
