MacOS – Parental Controls flooded system.log with errors

logsmacosparental-controls

I was digging around for fun, and found that my system.log was flooded with errors. Here is the output of sudo cat system.log | tail -8:

These seem to be messages from Parental Controls, but what do they mean? Also, they are going on all the time. Could anyone shed some light??

Best Answer

I had to remove the account with Parental Controls and stop using that feature. It became a CPU melter in my case. You may also want to upgrade to Mac OS X 10.6.8.
