Apple - Remove "Other..." from Login screen
I finally found a solution!
After some more search I found this command:
sudo defaults write /Library/Preferences/com.apple.loginwindow SHOWOTHERUSERS_MANAGED -bool FALSE
..and it did the trick!
I solved this a different way, a better way in my opinion, in my case the root user was active so I turned it off following Apple's instructions.
Just in case the above link stops working, these are the steps:
- System Preferences
- Users & Groups
- Unlock (bottom left)
- Login Options
- Join
- Open Directory Utility
- in Directory Utility Unlock (bottom left)
- In Edit Menu, select Disable Root User
Note: I don't know why the root user was active. It might have something to do with the Guest User or with Find My Mac.
It can be changed by using Terminal command:
sudo defaults write /Library/Preferences/com.apple.loginwindow SHOWOTHERUSERS_MANAGED -bool FALSE
One can also revert back:
sudo defaults write /Library/Preferences/com.apple.loginwindow SHOWOTHERUSERS_MANAGED -bool TRUE
