Well, lo and behold, I actually fixed it. This is what I did:
- Turn off parental controls for all accounts
- Make a new user account
- turn on parental controls only for the new account, set web browsing to unrestricted
- log in to the new account
- log out of the new account
- delete the new account
- Turn parental controls back on for the accounts that needed them
- Log in to the managed accounts and see if browsing now works
Voila! It works! Hopefully it will work for some of you too.
You rock! Just updated to the new OS and discovered the same problem everyone else has stated. Thank you for the work around - saved major homework headaches to night. Now, if Apple would just fix the bug parents everywhere would be much happier.
I wonder if we would have had the same problems if we had turned off parental controls before the update?
My problems started with ML 10.8. I upgraded to 10.8.1 a few weeks ago, hoping the problem had been addressed, but I still lacked access to certain sites when PC was enabled. I decided not to upgrade to 10.8.2 after I read all the problems encountered with that version.
I don't want some quick fix, I want an operating system that has working parental controls! Is that too much to ask?
I've tried a number of work-arounds as suggested on this thread but none work. The only thing that stops the security warnings is deleting the account, creating it again and allowing unrestricted web access in parental controls.
The main problem for me comes from url references that are hidden from the user. For instance http://www.google.co.uk pops up a security warning for multiple https urls that I've not tried to get to - they are linked to in the site code. The the amount of similar hidden links (trackers, advertisers, facebook 'like' button links ......) makes the whole thing unusable.
Here's a screenshot example (even opening the Skitch application to take the screenshot caused two https warnings!):
Here is the solution that worked for me. I have done it on 4 different Macs and it has worked everytime. The problem appears to have been around for several years and keeps popping back up with various updates to OS/X. There seems to be some issue created when you turn on Time Limits under the Bedtime section which creates the problem. You need remove those settings and then disable the logging that is done for the family controls. Here is how to do it:
1: Logon as a user with administrator permissions.
2: Open the Parental Controls settings for the user. Go to the Time Limits section. Remove any check boxes and settings under the Bedtime section such as School Nights or Weekends.
3: Run the Terminal app. Enter the following line in the terminal app. Make sure you replace username with the actual username of the user you are trying to fix. It will probably ask you for a password which is your password as administrator.
/usr/bin/sudo /usr/bin/dscl . -mcxset /users/username com.apple.familycontrols.logging web always -bool false
4: Logout and test the user
MaxPowerBE I have tried your SOLUTION on numerous macs and I'm sorry but it doesn't really fix anything.
There are at least 7 documented bugs for parental controls in this thread and all of them return after a reboot.
