SecurityAgent needs to make a change
Every time i reboot my MacBook Pro and login to my Standard account. I get the above message and it prompts me for the Admin account and password.
Has anybody else seen this?
Does the screen/window indicate what that change is? Does it happen if you login to an admin account?
I'm currently getting this exact same message. Have you found a solution yet?
Try booting into safe mode, log into the problem account, then restart and the popup should go away. At least, it worked for me!
