Hello. I received a macbook and am currently the administrator on it. Or at least I was until recently. You see, my macbook air is continuously changing my status from an administrator to a standard user. This has happened twice and I don't know how to prevent this from happening again. I've tried to use single user mode, terminal, and the entire internet. The only thing that works is when I remove the setup file and set the mac back to factory settings. It works but the status changes in minutes to all of my administrative accounts. However, it may be doing this after I conduct an action permitted only to administrators. Either way I don't know what causing this or how to prevent this from happening again. Please help!
