Changing the administration name on a MacBook can be a crucial step for users who want to personalize their device or reflect new ownership. The administrator account controls key aspects of the system, including software installations, settings changes, and user management.
Whether you’ve purchased a second-hand MacBook or simply want to update your name for clarity, understanding how to change the admin name safely is important. This process varies slightly depending on whether you want to change the full name displayed or the actual account name used by macOS internally.
Unlike simply changing your user profile’s display name, modifying the administrator account name involves a few more steps to avoid system conflicts. If done incorrectly, it could lead to login issues or loss of access to files.
That’s why it’s essential to carefully follow the right procedure and back up your data before attempting any changes. By doing so, you’ll keep your MacBook running smoothly while updating your personal information.
In the following sections, we’ll explore several methods to change your MacBook’s administrator name, including how to update the full name, the home folder name, and what precautions to take. We’ll also discuss what to do if you want to create a new admin account entirely.
Along the way, we’ll share insights and tips to make this a straightforward experience.
Understanding the MacBook Administrator Account
Before changing the administrator name, it’s important to understand what the admin account represents on macOS. The administrator has elevated permissions that allow changes affecting all users and the system itself.
The administrator account is different from a standard user account in that it can install software, modify system settings, and manage other user accounts. This elevated access is why caution is necessary when changing anything related to the admin account.
One key point is that the “Full Name” displayed on the login screen and in System Preferences is different from the actual short username used by macOS internally. Changing the displayed name is simple, but altering the short username requires more steps.
“The administrator account is the gateway to your Mac’s control panel; treat changes to it with care to avoid unintended lockouts.”
Full Name vs. Account Name
The Full Name is what appears on the login screen and in the user list under System Preferences. It’s mostly cosmetic and can be changed easily without affecting the system.
The Account Name (or short name) is the actual username folder name in the system’s Users directory. This is tied to your home folder and system permissions, so changing it improperly can cause issues.
Understanding this distinction helps you decide which name you want to change and how to do it safely.
How to Change the Displayed Administrator Name
Changing the displayed administrator name is the simplest way to update how your MacBook shows your name without touching the system’s internal username. This method impacts only what you see on the login screen and in the Users & Groups preferences.
To do this, you need to access the Users & Groups section in System Preferences, where you can update your full name with ease. This approach does not affect your home directory or account permissions.
Here are the basic steps:
- Open System Preferences from the Apple menu.
- Select Users & Groups.
- Click the lock icon and enter your administrator password to make changes.
- Right-click your administrator account and select Advanced Options.
- Update the Full Name field to your desired name.
- Click OK and restart your Mac to see the changes.
Because this change is purely cosmetic, you won’t risk system instability or loss of access to files. This makes it ideal for users who simply want to refresh their MacBook’s welcoming screen.
“Changing your Full Name is a quick way to personalize your Mac without digging into complex system settings.”
Changing the Account Short Name (Username) Safely
Altering the short username—the actual account name macOS uses—requires more care. This name corresponds to your home folder and is used by the system to identify your files and permissions.
Changing the short name incorrectly could cause your MacBook to fail to log in or lose access to important files. Therefore, it’s essential to follow a safe process that includes creating a backup and renaming the home folder properly.
To change the short name, follow these steps:
- Create a full backup of your Mac using Time Machine or another backup solution.
- Log out of your administrator account and log in with a different administrator account. If you don’t have one, create a new temporary admin account.
- Rename the home folder in the /Users directory to the new short name.
- Go to System Preferences, then Users & Groups, and open Advanced Options for your original admin account.
- Change the Account Name and Home Directory fields to match the new folder name.
- Restart your Mac and log in with the updated account name.
Why Backup Is Crucial
Backing up is essential because you risk losing access to your files if the renaming process is interrupted or incorrectly performed. Time Machine is a reliable option that saves a snapshot of your entire system.
If you encounter any issues, you can restore your Mac to its previous state without data loss. This safeguard ensures peace of mind as you change core system elements.
Important: Always make sure you have at least one active administrator account before modifying usernames to avoid being locked out of your Mac.
Creating a New Administrator Account and Deleting the Old One
Sometimes, the easiest way to change the administrator name is to create a new administrator account with the desired name and then remove the old one. This method avoids the complexity of renaming the account and home folder.
This approach is particularly useful when transferring a MacBook to a new user or when the old admin account is no longer needed.
Steps to create a new admin account:
- Open System Preferences and navigate to Users & Groups.
- Click the lock icon and authenticate to allow changes.
- Click the plus (+) button to add a new user.
- Select Administrator from the dropdown menu and enter the new user details.
- Log out of your current account and log in to the new admin account.
- Return to Users & Groups and delete the old admin account if desired.
What Happens to Your Data?
When deleting an old admin account, macOS gives you options to save or delete the user’s home folder. If you want to keep your data, choose to save the home folder as a disk image.
This process ensures you don’t lose important files while transitioning to a new administrator account.
| Option | Effect |
| Save the home folder as disk image | Preserves user data in a compressed file for later access |
| Delete the home folder | Removes all user data permanently from the system |
| Keep the home folder | Keeps user data in the /Users folder accessible to other accounts |
Potential Issues and How to Avoid Them
Changing your MacBook administrator name is generally straightforward if you follow the right steps, but some issues can arise during the process. Awareness of common pitfalls will help you avoid them.
One common problem is losing access to files because the home folder name no longer matches the account name. This leads to permission errors and login failure.
Another issue is accidentally deleting the only administrator account, which can prevent you from making system changes or installing software.
- Always back up your data before making any changes.
- Make sure you have at least one active admin account at all times.
- Rename your home folder and account name simultaneously to keep them synced.
“Taking your time and double-checking each step can save you hours of troubleshooting later.”
Changing Administrator Name on macOS Ventura and Later
With the release of macOS Ventura and later versions, some system settings have shifted locations, and security features have tightened. This affects how you change your administrator name.
While the basic principles remain the same, the interface for accessing user accounts and advanced options has been updated for improved security and clarity.
To change names on macOS Ventura or later:
- Open System Settings instead of System Preferences.
- Navigate to Users & Groups, which may be nested under Privacy & Security.
- Authenticate and select your admin account, then choose Advanced Options.
- Make your changes carefully and restart your Mac.
Because macOS now includes enhanced security protocols, you might be prompted to enter your Apple ID or perform two-factor authentication during these changes.
Additional Tips for Managing User Names on Mac
Besides changing the admin name, you can improve your MacBook experience by managing user accounts strategically. This includes assigning clear names, setting appropriate permissions, and organizing profiles.
Consider these tips to optimize user management:
- Use descriptive full names for easier identification on login screens.
- Assign administrator privileges only to trusted users to maintain security.
- Regularly review and remove unused accounts to free up space and reduce clutter.
Effective user management complements your efforts to personalize your MacBook and maintain a secure environment.

Troubleshooting Common Problems After Changing Admin Name
Even when following instructions closely, you might encounter unexpected issues after changing your MacBook’s administrator name. Knowing how to resolve these problems quickly is essential.
Common problems include login failures, missing files, and permission errors. These typically stem from mismatches between the account name and home folder or incorrect permissions.
To troubleshoot:
