I am new to Mac OS (using Mojave on a MacBook Air 2017) and am running into an issue. I want to create a hidden local admin account that only I know exists. I followed a guide and enabled users under ID 500 to be hidden and got that to work. I then changed login options to "display name and password". When I logged out it seemed everything was fine. But after a reboot, both accounts showed up with their name. Is there anyway to prevent the admin account from showing up after a reboot?
Thanks all ~
