UGH! Help...Admin User converted to Parental Controls now Admin Password doesn't work
Ok, so my wife asked me to put Parental Controls on our iMac so my son only has a certain amount of time on the iMac. Unfortunately I did have a lot of time and I tried to do it quickly by converting my login to a PC login account. It is the only login on the iMac and now I am locked out. I tried unlocking the PC settings and it asks for an Admin and Password. I put the original Admin and Password and it won't accept it obviously since I am no longer and Admin. I am running Mountain Lion.
Please help!!!
iMac, iOS 7.1.1
