what if the parental control is eabled for administrator, how to disable the parental control?

1st option

Try to log on on an another admin account on your Machine and change that.

2nd option

if there is no other admin you have to create a new user as an admin.

Reboot. When the screen goes black hold "command- s" to enter in Single user mode

type /sbin mount -uw /

its /sbin(space)mount(space)-uw(space)/

then enter

type rm /var/db/.AppleSetupDone

its rm(space)/var/db/.AppleSetupDone

enter

Type Reboot

enter

The system, will restart with like setting up a new machine (dont worry your user files are not deleted)

set up a new account. then after that check teh user accounts on system prefrences. remove managed and boot on to your pervious user.

After managing to make your Previous usre an admin delete the other extra user that you created

Try to enable firmware password so that you can only do that to your machine. http://support.apple.com/kb/HT1352

When you first installed OS X, an administrator account was created. Its like deleting the .applesetupdone. The New account that you created should always be the Admin. I dont know what happened there.

Login to the newly created User (that yousaid is anon admin). Open Terminal App

type this

sudo dscl . -append /Groups/admin GroupMembership RealName "<

Your USER ACCOUNT NAME>

"

it will ask you for password. Type the password of your newly created account. If it does not work use the password of your previous admin account. If not we are going to reset the "root admin" password for this to work. You will need the Snow Leopard DVD to do that.

Reset the password with the Installer Disk.

Boot from DVD and use the Password Reset program

I tried it and the new user is "Admin, Managed". I uncheck the "Enbale Parental controls " and left the "allow User to administer" checked.
