Change Your Account Name in System Settings

The fastest way to change your name on a MacBook is through System Settings. Open System Settings, click on "General" in the sidebar, then select "About". You will see a field labeled "Computer Name" — this is the name that appears in Finder and on your network. Click the "Edit" button next to it, type your new name, and click "Done".

This changes only the device name, not your user account name. If you want to change the name associated with your user account — the one that appears in login windows and at the top of the Apple menu — you need a different step. Go back to System Settings, click "General" again, then scroll down and select "Users & Groups" (or "Login Items" depending on your macOS version). You may need to click the lock icon and enter your password to make changes.

Key Takeaways

  • Your MacBook has two separate names: the computer name (visible on your network) and your user account name (visible at login and in the Apple menu).
  • To change the computer name, open System Settings, go to General, click About, and edit the Computer Name field.
  • To change your user account name, you must go to System Settings and access the user account settings, which may require administrator password entry.
  • Some older versions of macOS use "System Preferences" instead of "System Settings" — the location is the same but the app name differs.

Change Your User Account Name (The Name You Log In With)

Your user account name is different from your computer name. This is the name that appears when you log in, in the Apple menu at the top right, and in file ownership. To change it, open System Settings and look for "Users & Groups" or "Login Items" in the sidebar. Click the lock icon at the bottom left, enter your administrator password, then right-click your account name and select "Advanced Options".

In the Advanced Options window, you will see a field labeled "Account name" — this is the short name used by the system for file paths and permissions. You can also change the "Full name" field, which is the display name. Change whichever you need, then click "OK". You may need to restart your Mac for the change to take full effect, especially if you changed the account name itself.

What Happens When You Change Your Account Name

When you change your user account name, your home folder path does not change automatically. Your files remain in the old folder location (usually /Users/oldname). This usually causes no problems — your Mac will still find your files — but some applications may lose track of preferences or settings stored in your home folder. Restarting your Mac after the change helps most applications re-index their settings.

If you change the full name only (not the account name), nothing breaks. The full name is purely a display label. If you change the account name itself, back up your Mac first using Time Machine or another method. The change is reversible, but having a backup means you can restore quickly if an process stops working.

Change Your iCloud Account Name (Apple ID Display Name)

Your iCloud account has its own display name, separate from your MacBook user account name. This is the name that appears in iCloud settings, on shared documents, and in messages to other Apple users. To change it, open System Settings, click "General" in the sidebar, then select your Apple ID at the top. Click "Name, Phone, Email" and edit the name field. This change takes effect when ready across all your Apple devices.

Changing your iCloud display name does not change your Apple ID email address or your MacBook user account name. It is purely cosmetic and affects only how your name appears to other people in Apple services.

Rename Your Computer for Network Visibility

If your MacBook appears on a shared network or you use AirDrop with other devices, the computer name is what others see. To change it, open System Settings, go to "General", then click "About". The "Computer Name" field is at the top. Edit it to whatever you want — this name appears in Finder's sidebar under "Shared" and in AirDrop discovery. Click "Done" when finished.

The computer name can contain spaces and special characters, unlike the user account name. Choose something you will recognize on a network with multiple devices. The change takes effect when ready, though some applications may need to be restarted to see the new name.

Troubleshooting Name Changes That Did Not Work

If you changed your account name but your Mac still shows the old name in the Apple menu, restart your Mac. Some system processes cache the name at startup. If the change still has not taken effect after a restart, open System Settings again, go to Users & Groups, and verify the change was saved — sometimes the system reverts the change if a permission issue occurred.

If you cannot edit your account name because the lock icon will not unlock, you may not have administrator privileges on this account. Ask the administrator of the Mac to make the change, or create a new administrator account if you are the only user. If you changed your account name and now an process will not launch, try restarting that process or your entire Mac. If the problem persists, check the process's preferences to see if it is still looking for files in the old home folder path.

Frequently Asked Questions

Can I change my MacBook name without restarting?

Changing the computer name takes effect when ready without a restart. Changing your user account name may require a restart for all applications to recognize the change, though many will work fine without one. Restarting is the safest approach if you changed your account name.

Will changing my account name delete my files?

No. Your files stay in your home folder and remain accessible. The folder path does not change automatically, so your Mac continues to find everything. Some applications may temporarily lose track of settings, but restarting usually fixes that.

What is the difference between computer name and account name?

Computer name is what your MacBook is called on a network — others see this in AirDrop and shared folders. Account name is the name you log in with and the name of your user folder. You can change both independently.

If I change my name, will my iCloud account be affected?

Changing your MacBook user account name or computer name does not affect iCloud. Your iCloud account is tied to your Apple ID email, not your device name. You can change your iCloud display name separately in System Settings under your Apple ID.

Do I need administrator access to change my account name?

Yes. You must be logged into an administrator account or know an administrator's password to change any user account name on the Mac. If you are the only user, your account is already an administrator.
