I'd like to know how to hide a user from the OSX login screen. I'd like to have a hidden administrator account for using ARD, rather than the user's main account.

Any hints, tips and ideas?

I can hide users in question by doing the following:

sudo defaults write /Library/Preferences/com.apple.loginwindow HiddenUsersList -array-add 'newadmin'

You could enable root, which would give you admin rights and not create an account at the login screen.

  • That would work, I'm sure - but I'd like to not have an active root user on 200+ "linux" boxes – Mister IT Guru Jun 13 '12 at 11:03

    @Mister IT Guru, make up your mind. Is it OS X or Linux? Similar != the same. – John Gardeniers Jun 13 '12 at 12:00
  • I know, I know, apple fan boys hate OSX, which is a BSD derivative being called linux! :) – Mister IT Guru Jun 13 '12 at 12:23
  • @MisterITGuru: Nonsense. If you are looking for help, please be specific. As John said, OS X and Linux are somewhat similar, but not the same (by a long shot), so which one is it? – Sven Jun 13 '12 at 13:08
  • @SvenW Okay, keep calm here, please point out the nonsense? I think I was VERY clear in my question, OSX is the OS which I am asking about. I was also being jovial when I put LINUX, in " " - I was inferring, (as should be expected of every sysadmin with security in mind), that exposing the root user to active logins in A BAD IDEA. In this respect, the ENVIRONMENT EXPOSURE would be EXACTLY like linux, unix, and any other OS that uses similar architecture for authentication, and process control. I look forward to your followup comment. Thank You – Mister IT Guru Jun 13 '12 at 13:32
