The built-in administrator account is created when your Mac starts up for the very first time, and it’s automatically protected by a password. If you’re using FileVault encryption (a feature you should), this means that no one can log in to the computer without knowing the admin password, even if they manage to reset or remove your user account. This also means that you can assume an Apple Genius won’t be able to assist you with anything related to FileVault—it’s simply not something they deal with, since there is no way (that we know of) to change or remove the admin password from another Mac.
If you want to try uninstalling the admin account, here are the steps to do it:
Go to System Preferences > Accounts and click the lock at the lower left corner of the window. Enter your password when prompted, then unlock by clicking on the “unlock” icon.
Click on Administrator in the list below (yep, that’s what we said: You have to select this account before you can delete it!)
Backup up or export all of your documents, photos and movies onto an external hard drive or online storage service like Dropbox as a precautionary measure. Then click on the – sign next to Administrator’s name.
You have now successfully deleted your admin account from macOS! If you want to use FileVault again, you will either need to re-enable an existing admin account or create a new one. Once you’ve done that, just go through these steps again and follow the prompts to enable FileVault when prompted. You can also find instructions here if this is your primary Mac: How To Turn On FileVault Encryption for your Mac.
Note: If you choose to delete the administrator account by navigating directly to System Preferences > Users & Groups, there is no way (that we know of) to get it back afterwards! Anytime you log in with a non-administrator account on macOS Sierra or later, you will see that the “root” user has been created—this means that Apple has already taken steps to recover the admin account for you.
How do I remove hidden administrator accounts?
Apple recommends that you don’t delete the root or guest user—even though they’re listed in your Users & Groups preferences window, deleting them will cause issues with future OS X updates and system configuration changes. If you want to create a new admin account without losing additional functionality, here are the steps:
Go to System Preferences > Users & Groups > Click on Guest User (or select “root” if you prefer) and click on the – sign next to their name. After confirming the action by clicking on Remove User, you should be able to create a new admin account as normal.
If the removal of an account using the above steps doesn’t work, you may need to completely erase your Mac. To do this, go to Apple Menu > Restart and hold Option + Command + R until Recovery Mode loads.
Note: If your hard drive is encrypted with FileVault 2, you will first need to log in using an existing admin user before entering recovery mode.
How do I remove a non-administrator from my Mac?
The easiest way to remove a non-admin user from macOS is by deleting their Home folder. Here are the steps for doing so:
Select the Finder (or use Spotlight) to search for all items that belong to the user whose documents you want to delete. Open the folder and select all of their files.
Once you’ve done that, you can either drag and drop them to the trash or right click on them in Finder and then press Move To Trash. After
you’ve deleted all of their files, don’t forget to empty the trash as soon as possible so you can prevent anyone else from accidentally recovering the user account and documents.
Note: If you want to delete an admin user who is no longer using your Mac, you will have to log in with a non-admin user first and then launch Terminal. Once there find out the full file path to that user’s home folder by using this command: `dscl . list /Users` (The “.” is actually two periods back-to-back). Next, run this command followed by the filepath: dscl . -delete /Users/oldusername, then finally enter rmdir /Users/oldusername to remove the folder. If you are still having issues, try this: PowerPC Instructions or Intel Mac Instructions.
Can I use Terminal Commands To Manage User Accounts?
Absolutely! There are a few ways to change account ownership. First, you can use the dscl tool that comes pre-installed with OS X. If you want to run it manually, here’s how:
Open Terminal (found in /Applications/Utilities). Enter `dscl .` and browse through the list for accounts by pressing Spacebar. When you find an account that you like, just enter your admin username and hit Return to assign it as Owner of that document or folder.
If this command isn’t working for some reason, there is another way to manage ownerships using chown and sudo commands only: Here are step-by-step instructions on how to do so: 1. Open a new Terminal window. 2. Enter `sudo chown -R username filepath` (Replace “username” with the name of the user you want to assign ownership). 3. Press Return to confirm any warnings that may appear on your screen and, if prompted, enter your admin password.
Note: If you get asked by an App Store program about making changes to core system files or using sudo command, click on [Continue Anyway] button below these alerts. This will just let OS X know that yes, you are allowed to use such commands because you are an administrator!
How do I set passwords for my Mac?
Setting a strong password is one of the most important security measures that we can do to protect our Mac. If you haven’t set a password yet, take the time to learn how to do so now because it’s really easy and free!
1. Open System Preferences > Users & Groups 2. Click on your account 3. In the Password field, enter a new password 4. Confirm your new password by re-entering it in both fields 5. Click OK
Here are some tips for creating a strong password:
To make a stronger password, try using at least one special character ( [email protected] [email protected] or #) and at least eight characters even if you only need to type it once every few weeks.
Try not to use dictionary words or commonly used passphrases.
Note: If you are worried about weak or strong passwords for some reason, there is a macOS app called Keychain Access that can help you manage your stored usernames and passwords in a secure way. It keeps them encrypted with one master password that you should only need to enter every few weeks when it prompts; this helps prevent hackers from stealing your data easily.

Do I Really Need A Password & What About Touch ID?
Touch ID is just an added convenience feature for ease of use (and because Apple really wants everyone upgrading to iOS 9 and OS X El Capitan). If someone manages to get physical access to your Mac, they can easily bypass the touch security mechanism to get inside without having a registered fingerprint. In addition, attacks to circumvent this are likely on the rise so if you have set up a password with your administrator account, it is very unwise not to use it.
