I have a minimac and recently added my grandchildren as users. I used the parental control options when setting their own log ins but need to make some changes. This is where all my dramas began. I have tried every which way to gain access to their account but am blocked out. I even set up a root administrator account and still cannot gain access. Hopefully there is someone out there who has done the same thing and found a way around it. If so please help me. Thankyou.
