Step-by-step Guide to Change Username on Mac

Before proceeding, ensure that you have a backup of your important data. Changing the username can often lead to unexpected results, including data loss.

Step 1: Create a New Administrator Account

Before you can change your username, you must create a new administrator account. This is necessary because you cannot rename a user account that is currently logged in.

  • Click on the Apple menu and select System Preferences.
  • Click on Users & Groups.
  • Click on the lock icon and enter your password to make changes.
  • Click on the +’ icon to create a new user account.
  • Select Administrator from the New Account drop-down menu.

Step 2: Log Out and Log in to the New Administrator Account

After creating the new administrator account, log out from the current account and log in to the new one.

Step 3: Rename the Home Folder

Now, it’s time to rename the home folder. The home folder name should be identical to your desired username.

Here are the steps:

  • Open Finder and click on Go in the menu bar.
  • Select Go to Folder.
  • Type /Users and click Go.
  • Right-click on the home folder you want to rename and select Rename.
  • Enter your desired username.

Step 4: Change the Username and Home Folder in Users & Groups

After renaming the home folder, you have to change the username and home folder in Users & Groups.

  • Go back to System Preferences and select Users & Groups.
  • Click on the lock icon and enter your password to make changes.
  • Right-click on the username you want to change and select Advanced Options.
  • Replace the old username and home folder with the new one.
  • Click OK to save the changes.

Step 5: Log Out and Log in to Your Renamed Account

Finally, log out from the new administrator account and log in to your renamed account. Now, you should see your new username.


Changing the username on Mac is not as straightforward as it is on some other operating systems. However, by following these steps, you can easily change your username without any hassle. Remember to backup your data before proceeding, and if you experience any issues, don’t hesitate to contact Apple Support.
