Read through the steps mentioned in this post to learn all possible reasons but the major reason why I was unable to delete managed user account was related to directory Utility. There could be multiple reasons of user account not being deleted.
#Remove redhand from system preferences mac mac#
Unable to delete managed user account from Mac Initially I tried to delete it in safe mode and also from terminal but that did not help and the managed user account could not be deleted. I was not able to delete the managed user account from my Mac until I did some research and found a solution. However, sometimes if you try to delete an account, the system may become so stubborn and refuses to allow this action, so the account reappears when you next launch the system preferences or it does not allow you to delete one of the accounts at all because the delete button ( a minus sign ) at the bottom of the list of Users stays grayed out even after opening the security lock.One of the such incidents happened to me when I tried to delete one of the managed accounts (Account with parental controls) on my Mac. You can add or remove a user from Users and Groups under system preferences. If you are the primary user who manages the computer then you should be an administrator on your Mac.Users are further divided into multiple categories ( Standard, Admin, Managed and Sharing only ) depending upon the rights and privileges assigned to them which are managed from Users and Groups option under System Preferences. If you have multiple users for your Mac, you should set up an account for each person so that each can personalize their settings and options without affecting the others.

Users are like different accounts with their own settings and privileges in OS X system.

Unable to delete one of the user accounts from system preferences? Strange ?!!! isn’t it?
