Changing the admin name on a Mac is a common query among users who want to personalize their device or maintain better control over their digital identity. The admin name, also known as the account name or username, plays a crucial role in how the system identifies you and manages permissions.
While it might seem straightforward to update the admin name, the process involves a few technical steps that require caution to avoid disrupting your Mac’s functionality. Whether you’re looking to tweak your profile for privacy reasons or simply want a fresh start, understanding the nuances of changing the admin name is essential.
MacOS organizes users and their privileges through these admin accounts, and changing the admin name is not just about altering the display name; it also involves changing the underlying folder and permissions.
Many users confuse the full name (the display name) with the account name, but they are distinct, and altering one doesn’t automatically change the other. This distinction often leads to confusion during the process.
Before diving into the steps, it’s important to back up your data, as any misstep could lead to access issues. With the right precautions and knowledge, you can effectively change your Mac’s admin name and enjoy a smoother, more customized user experience.
Understanding the Difference Between Admin Name and Full Name
Before attempting to change any name on your Mac, it’s crucial to understand the difference between the admin name and the full name. These terms are often used interchangeably, but they refer to different elements within your Mac’s user account system.
The full name is the user-friendly display name that appears on the login screen and in the system preferences. It’s what you see when you invite someone to use your Mac or when you view the user list.
On the other hand, the admin name, also known as the account name or short name, is the key identifier for your user account inside the system. This name is tied to your home folder and system permissions.
Why Does This Matter?
Changing the full name is simple and safe, but changing the admin name requires more care because it involves renaming your home folder and adjusting system references.
- Full Name: Display name, can be changed easily in System Preferences
- Admin Name: Account/short name, tied to system files and home directory
- Home Folder: Located in /Users, named after the admin name
“The admin name is more than just a label; it’s integrated deeply into the system’s architecture.”
Understanding these differences helps you decide the level of change you want to make and the risks involved.
Changing the Full Name (Display Name) on Mac
If you only want to change the name that appears on the login screen or in the user list, you can easily update the full name without touching the admin name.
This process is straightforward and safe as it does not alter any system permissions or folder structures. It simply changes the way your name appears visually.
Steps to Change the Full Name
First, open System Preferences and navigate to Users & Groups. Click the lock icon to authenticate with your current admin password.
Then select your user account from the list.
Right-click or control-click your user and select Advanced Options. Here, you will see the “Full Name” field, which you can edit to your preferred display name.
- Open System Preferences > Users & Groups
- Unlock settings with admin password
- Right-click user > Advanced Options
- Edit the “Full Name” field
After changing the full name, click OK and restart your Mac to see the changes. This method is ideal for users who want a fresh name without complicated technical adjustments.
Changing the Admin Name Safely
Changing the admin name (or account short name) is more complex because it involves renaming your home folder and updating system settings to reflect the new name. Doing this incorrectly can lock you out of your account or cause system errors.
Thankfully, with careful steps, you can rename your admin account safely, but it requires administrator privileges or access to another admin account.
Step-by-Step Guide to Rename Admin Name
First, log out of the user account you want to rename. Then log in to another admin account.
If you don’t have another admin user, you’ll need to create one temporarily.
Navigate to the Users folder in Finder (/Users) and rename the home folder of the account you want to change to the new admin name. The new folder name must exactly match the new admin name you plan to use.
Next, open System Preferences > Users & Groups, unlock with an admin password, right-click the user and select Advanced Options. Change the “Account name” field to match the new folder name.
- Log in to a different admin account
- Rename the home folder in /Users
- Update “Account name” in Advanced Options
- Restart and log in with new admin name
“Renaming your admin account is a delicate process that should not be rushed or done without backup.”
This process ensures your Mac recognizes the new admin name and links it correctly to the home folder.
Potential Risks and How to Avoid Them
Changing the admin name incorrectly can lead to file permission issues, loss of access to your account, or even data loss. It’s important to proceed with caution and understand the risks involved.
One common problem arises when the home folder name doesn’t match the account name, causing the system to create a new temporary home folder on login.
Precautions to Take
- Always back up your data using Time Machine or another backup method before attempting any changes.
- Use a separate admin account to make changes to avoid being locked out.
- Ensure folder names and account names match exactly including capitalization.
- Be patient and double-check each step to prevent mistakes.
If you encounter issues after renaming, you might need to reset permissions or restore from backup. For more tips on managing user accounts, consider exploring how to handle multiple accounts with different names.
Using Terminal to Change Admin Name
Advanced users might prefer using Terminal commands to change the admin name. This approach offers more control but requires familiarity with command-line operations.
Using Terminal, you can rename the home folder, update the user record, and fix permissions all in one place. However, incorrect commands can cause permanent damage.
Key Terminal Commands
| Command | Purpose |
| mv /Users/oldname /Users/newname | Rename home folder |
| sudo dscl . -change /Users/oldname RecordName oldname newname | Change account short name |
| sudo chown -R newname /Users/newname | Fix folder permissions |
After executing these commands, reboot your Mac and log in with the new admin name. Always verify each step, and consider consulting detailed resources or professional help if unsure.
“Terminal offers great power but also great responsibility when it comes to system modifications.”
How Changing Admin Name Affects Your Mac Experience
Changing your Mac’s admin name impacts several system areas, including file permissions, login credentials, and even app configurations. Understanding these effects helps you prepare for any adjustments you may need to make afterward.
For example, applications that store settings in your home directory will continue functioning normally if the home folder is renamed correctly. However, shortcuts or scripts referencing your old admin name may break.
File sharing services and network connections might require reconfiguration if they rely on your previous account name. Additionally, some third-party apps may cache your old username and need manual updates.
- File permissions must be updated to match the new admin name
- Network shares and services may require re-authentication
- Scripts and shortcuts might need editing to reflect the new path

When to Consider Creating a New Admin Account Instead
Sometimes, changing the admin name is more trouble than it’s worth, especially if you want a completely fresh start. In such cases, creating a new admin account might be a better solution.
This approach lets you set up a new profile with your desired admin name from scratch while keeping the old account intact for backup or reference.
Once the new account is created and verified, you can transfer important files and preferences and then delete the old account if desired.
- Create new admin user in System Preferences > Users & Groups
- Transfer essential files manually or via Migration Assistant
- Delete old admin account if no longer needed
This method eliminates the risks of renaming system folders and account names. However, it requires some time for setup and data transfer.

By understanding the difference between the full name and admin name, you can decide the best route to achieve your desired outcome.
