How to Change Mac Username: A Comprehensive Guide

Mac Username Changing Tutorial

Welcome to another tutorial video, but this time we are focusing on Mac computers! 😊Today we’re getting hands-on with a task you may have wondered about or needed to do, but haven’t quite figured out: changing your Mac Username. I’ll show you how to modify not only the name you see when you log into your Mac, but also your account name. So, let’s get to it! 🖥️💡


Accessing System Preferences

The first thing you want to do is log into your account on your Mac. Then, go to the 🍏 Apple logo at the top of your screen, and click on it. In the dropdown menu, go to System Preferences and click on it. Where to next? Upgrade your permissions. 🔐


Unlocking User Permissions

Still in System Preferences, scroll down to the icon that says Users & Groups and click on it. On the left side, you’ll find a list of current users. Look for a lock icon at the bottom of this window. Choose Unlock and enter your password to gain access to make changes to the users. 🔓 Now, it’s time to change that username! 👨‍💻


Changing Your Username

After unlocking, right-click on the user you want to rename. Subsequently, you’ll see an option that says Advanced options. Click on this, but be prepared for warnings. 🚧 Reason being, changing a username or account name impacts files linked to your name, potentially including critical ones. Before proceeding, ensure you’ve created a backup of your Mac to avoid unwanted surprises. 📂🛡️


Editing Account Details

In the Advanced options, you’ll find fields to change your Full Name and your Account Name. Feel free to edit these as you like, then hit OK. Remember, the Account Name is what appears when logging in, while the Full Name includes spaces and capitalizations. After the changes, the new names will manifest in the Users & Groups section. 👥🔡


Changing the Primary Administrator Account Name

If the primary admin on the Mac is yourself, and you wish to change the account name associated with directories and files, note that this field is usually grayed out. However, there’s a workaround: login to another admin account, navigate back to Advanced options where now nothing will be grayed out. Change carefully, and always have a backup before making any changes! 👩‍💻🔄
