To prevent booting to alternative boot modes (e.g., Single User Mode), you simply have to enable a firmware password on your system. By default OS X does allow for this however, there is a quick security measure you can take to prevent it and ensure that only you can perform these actions. This method can be used to reset any administrative account status on any Mac system, and as a result you might be concerned that anyone can make these changes to your system. You can then set the account to access this one so all of the previous accounts' settings and data are applied to the new account. When you do this, the system will detect the old abandoned home folder of the previously deleted account and inform you that a home folder already exists.
The last step is to go back to the Users & Groups system preferences and create a new account but use the same user name as the previous account (ensure that the "short" name of the account matches the abandoned home folder in the /Users directory). To allow writing to the drive, run the following command: This is a very powerful mode to work in, but is very convenient for troubleshooting.īy default, when booting to Single User Mode the hard drive is set to a read-only state, which ensures that you do not make changes unless you explicitly tell the system to do so.

When your computer boots it will check for the presence of this file, and then bypass the setup assistant if the file is found.

This assistant is generally only used once when you install OS X, where it shows a basic interface while running with root privileges to set some core system features, including the first administrator account. This occurs quite rarely, but if it does happen, one quick but well-known and convenient trick for recovering administrative status on a system is to activate Apple's OS X setup assistant again.

However, there may be times, when after an OS upgrade or other major system configuration change, that the administrator privileges of an account might get stripped, leaving you with no way to change a number of system settings.
