The good news is that Apple provides built-in options to make this adjustment accessible to users of all levels.

In the following sections, we’ll explore the different ways you can change your MacBook’s name, what each name represents, and some helpful tips to keep in mind during the process. Whether you’re a casual user or a tech enthusiast, this guide will equip you with the knowledge to

Changing Your MacBook Account Name and Home Folder

Changing the account name and home folder on a MacBook is a more involved process than simply changing the display name. The account name corresponds to the short name or username used by the system, while the home folder contains all the user’s personal files and settings. It is crucial to proceed carefully, as improper changes can lead to account access issues or data loss.

Before beginning, ensure you have a complete backup of your data using Time Machine or another backup method. You will need administrator access and another admin account to make these changes.

To change the account name and home folder:

  • Log out of the account you want to rename.
  • Log in with a different administrator account.
  • Open the Finder and navigate to the `/Users` folder.
  • Rename the home folder of the account to the new desired name.
  • Open System Preferences and go to Users & Groups.
  • Unlock the pane by clicking the padlock and entering the administrator password.
  • Right-click (or Control-click) the user you want to rename and select “Advanced Options.”
  • Change the “Account name” and “Home directory” fields to the new name, ensuring the home directory path matches the renamed folder in `/Users`.
  • Click OK and restart the MacBook.

It is vital that the “Account name” and “Home directory” are exactly the same, or the user may not be able to log in properly.

Modifying the Computer Name in System Preferences

The computer name is the identifier used on networks and visible in AirDrop or Finder under the “Network” section. Changing this name does not affect your user account but helps personalize your MacBook in shared environments.

To change the computer name:

  • Open System Preferences.
  • Click on Sharing.
  • At the top of the window, you will see the “Computer Name” field.
  • Enter the new name you want your MacBook to display.
  • Close the window; the change is saved automatically.

This name is used by other devices on the network to identify your MacBook, so choose a name that is unique and easy to recognize.

Understanding the Different Names on Your MacBook

MacBooks have several types of names associated with them. Understanding their differences clarifies why multiple steps are needed to fully rename an account or device.

Name Type Description Where It Appears Change Method
Full Name The user’s display name shown at login and in system dialogs Login screen, user account settings System Preferences → Users & Groups
Account Name (Short Name) The username used for the home folder and system processes Terminal, home folder path, file permissions Users & Groups Advanced Options (requires renaming home folder)
Home Folder Name The folder containing user files and settings /Users directory Rename folder in Finder and update Account Name accordingly
Computer Name The device name used on networks and sharing services Network browser, AirDrop, Sharing preferences System Preferences → Sharing

Precautions and Troubleshooting Tips

Renaming user accounts and home folders is delicate and can cause issues if done incorrectly. Consider the following precautions:

  • Always back up important data before beginning.
  • Use a separate administrator account to make changes to avoid locking yourself out.
  • Ensure the new account name contains only alphanumeric characters and no spaces to prevent system errors.
  • Match the home folder name exactly with the new account name.
  • If you encounter login problems after renaming, reboot into Recovery Mode and use Terminal commands to verify and correct folder permissions.
  • Avoid renaming the default “Guest” or system accounts.

If you experience issues with file permissions or access, running the Disk Utility’s “First Aid” tool may help repair directory structures.

Following these guidelines ensures a smooth transition when changing your MacBook’s user and device names.

Changing Your MacBook’s Computer Name

The computer name on your MacBook is the identifier used by networks and AirDrop to recognize your device. To change this name, follow these steps carefully:

  • Click on the Apple menu () in the top-left corner of the screen.
  • Select System Settings (or System Preferences on macOS versions prior to Ventura).
  • Navigate to General and then select About. On older macOS versions, look directly for the Sharing pane.
  • Locate the Computer Name field at the top.
  • Click inside the field and enter the desired new name for your MacBook.
  • Close the System Settings window to save changes automatically.

This new name will be reflected across local networks and in services like AirDrop and file sharing.

Modifying Your User Account Name and Home Folder

Changing your user account name and the associated home folder requires additional care because it involves sensitive system settings. Follow these instructions to ensure a smooth transition:

  1. Create a Backup: Before proceeding, ensure you have a full backup of your data using Time Machine or another backup solution.
  2. Enable the Root User:
    • Open System Settings > Users & Groups (or Users & Accounts).
    • Click the lock icon and authenticate with an administrator password.
    • Go to the menu bar, select Edit > Enable Root User. Set a password for the root user.
  3. Log Out and Log In as Root:
    • Log out of your current account.
    • At the login screen, choose Other.
    • Enter root as the username and the password you set.
  4. Rename the Home Folder:
    • Open Finder and navigate to /Users.
    • Rename the folder of the user account you wish to change.
    • Ensure the new name matches the new short username you plan to use.
  5. Change the Account Name and Home Directory Path:
    • Go back to System Settings > Users & Groups.
    • Right-click or Control-click the user account and select Advanced Options.
    • Change the Account name (short name) to match the renamed home folder.
    • Update the Home directory field to the new folder path (/Users/newname).
    • Click OK to save.
  6. Log Out from Root and Back into Your User Account:
    • Log out of the root account.
    • Log in using your new username and password.
  7. Disable the Root User:
    • Return to System Settings > Users & Groups.
    • Use the menu to select Edit > Disable Root User.

This process ensures your account name and home folder are synchronized, preventing permission issues and login errors.

Changing the Full Name Displayed on Your Mac

The full name displayed on the login screen and in system preferences can be modified independently of your account name. To update this:

  • Open System Settings > Users & Groups.
  • Click the lock icon and authenticate to enable editing.
  • Select your user account from the list.
  • Click on your current full name or choose Advanced Options to edit the Full name field.
  • Enter the desired full name.
  • Confirm changes and close the window.

This change will affect how your name appears in dialogs, the login screen, and system interfaces but will not modify the account’s short name or home folder.
