How to change your account name and/or password on macOS

Note: Changing your account name (the name of your home folder) is a bit complex and may cause issues with your account. If you're unsure, it's recommended to consult with someone knowledgeable before proceeding or to only change the 'Full Name' of the account, which is a simpler and safer process.


Changing the 'Full Name' of Your Account:

  1. Click the Apple Menu: Start by clicking on the Apple icon in the top-left corner of your screen.
  2. Open System Preferences: In the drop-down menu, choose "System Preferences."
  3. Go to Users & Groups: Find and click on "Users & Groups."
  4. Unlock to Make Changes: Click the lock icon at the bottom left of the window. Enter your password when prompted.
  5. Select Your Account: On the left side, you'll see a list of user accounts. Click on your account.
  6. Change Full Name: Right-click (or Control-click) on your account name and choose "Advanced Options." Here, you can change the 'Full Name'. This is the name that appears at the login screen and in the Users & Groups section.
  7. Save Changes: After editing, click "OK" and then close the System Preferences.
