Fixing Mountain Lion Runaway parentalcontrolsd

We upgraded a machine to Mountain Lion (10.8.2), but found that parentalcontrolsd was running constantly with high CPU usage. The steps to correct the problem were found on the Apple Support Forums.

  1. Disable parental controls on all users.
  2. Delete the folder /Library/Application Support/Apple/ParentalControls
    Please note that this command is a little dangerous.[code lang=”sh” light=”true”]$ sudo rm -rf "/Library/Application Support/Apple/ParentalControls"[/code]
  3. Restart Mac.
  4. Enable parental controls again.

    Same here. My iMac 27″ late 2009 model became so slow after the upgrade. This post saved me. Thank you so much!

    There is no parentalcontrols file in /Library/Application Support/Apple/ParentalControls there is only the Airport folder

    If you miss the first ‘/’ off that path you will get to the local user ParentalControls folder which only contains Airport folder. The root /Library/Application Support/Apple folder should contain the ParentalControls folder.

    There’s no need to restart the Mac. You can open the Activity Monitor and quit the parentalcontrolsd process from there. I did that and my CPU utilization dropped down to 2-3% immediately.

    Thanks for the tip!
