What I Think

When troubleshooting your Mac, it helps if you can log in as a different user. Instead of creating a new user, you can enable Root. Here’s how:

1. Open Finder,
2. Browse to Applications -> Utilities,
3. Open Directory Utility,
4. Click the lock to make changes,
5. Enter your password when prompted,
6. From the Taskbar go to Edit -> Enable Root User,
7. Enter a new password for Root,
8. Confirm the password and click OK,
9. Close Directory Utility, and log out of your Mac,
10. At the login screen, click the picture for Other…,
11. Type the username root, with the password you previously set.

The root account should only be used when absolutely necessary, and when you know what you’re doing.
