Cannot disable user as administrator
Hi Apple community,
I have the computer set up using a standard account, however this morning I logged in as admin and clicked the box for the standard account that allows the user to 'administer this computer'. I needed to do this temporarily, or so I thought at the time, and planned to disable/ uncheck this box after I was finished. However now, the 'allow user to administer this computer' is greyed out and despite my best efforts I cannot uncheck it. Now I have an admin account and my normal user account with admin privileges which I do not want. I thought if I logged in to the true Admin account I could resolve it, but to no avail. Any help appreciated.
Jeff
