Recently I had to remove users from a Mac that was on a network only with SSH available.
In this document I use the user name “administrator” as the account that I do the work in and would like to keep, your user name may be different.
First we need to enable root
This will ask for a user name and password of an admin user then ask to create a root password and have you confirm it.
When done correctly you will see “dsenableroot:: ***Successfully enabled root user.”
Next we want to remove the users, note this will only remove the user access and not the files for that user.
sudo dscl . delete /users/Guest sudo dscl . delete /users/jdoe1 sudo dscl . delete /users/jdoe2 sudo dscl . delete /users/marketing
OPTIONAL: Force the startup video to play again for the first login
sudo rm -r /var/db/.AppleSetupDone
Now we will move, not delete, all of the previous user files into a directory we can easily access should we need them later. This is important if you don’t really know what people were storing.
mkdir /users/administrator/Desktop/OldUserFiles/ sudo mv /users/Guest /users/administrator/Desktop/OldUserFiles/ sudo mv /users/jdoe1 /users/administrator/Desktop/OldUserFiles/ sudo mv /users/jdoe2 /users/administrator/Desktop/OldUserFiles/ sudo mv /users/marketing /users/administrator/Desktop/OldUserFiles/
When done disable root
This will ask for a user name and password of an admin user.
When done correctly you will see “dsenableroot:: ***Successfully disabled root user.”
