Hide a user account in the macOS login window
1. Log in with an administrator account.
2. Use this Terminal command. Substitute the short name of the user that you want to hide for hiddenuser:
sudo dscl . create /Users/hiddenuser IsHidden 1
The user account will also be hidden in System Settings (or System Preferences) the next time it's opened. This command can't be used with the Guest user account. Find out how to manage the Guest user account.
If FileVault is enabled, a hidden user may still appear in the first login window when you turn on or restart your computer.
Show a hidden user account
If you want the hidden user to appear again in the login window, set the user's IsHidden attribute to 0:
sudo dscl . create /Users/hiddenuser IsHidden 0
If you want to, you can delete the IsHidden attribute instead.
Hide the home directory and share point
This command will hide the "/Users/hiddenuser" home directory:
sudo chflags hidden /Users/hiddenuser
These commands will remove the Public Folder share point for the user with the long name "Hidden User":
sudo dscl delete Local/Defaults/SharePoints/Hidden\ User’s\ Public\ Folder/ exit
