Renaming Your Mac: A Guide to AirDrop, Bluetooth, and Beyond

Many Mac users accept the default name assigned during setup, but a descriptive name offers significant advantages, particularly for AirDrop and Bluetooth connectivity. This guide explains why and how to rename your Mac, home folder, and username.

Why Rename Your Mac?

Beyond personal preference, several compelling reasons exist for changing your Mac's name:

• Improved AirDrop and Bluetooth: Clear, easily identifiable names prevent confusion when transferring files or pairing devices. Generic names hinder quick identification among multiple devices.

• System-Wide Consistency: A well-chosen name simplifies commands in Terminal and improves overall system navigation.

• Multiple User Accounts: Distinct names for each user account enhance organization and prevent accidental access.

• Network Management: Easily identify your Mac on your home network, simplifying troubleshooting and security management.

How to Change Your Mac's Name

Follow these simple steps to update your Mac's name:

1. Click the Apple menu (top left).
2. Select "System Settings" > "General".
3. Click "About".
4. Click your current Mac name.
5. Type your desired name.

Renaming Your Home Folder

To rename a user's home folder, you must first log out of that account and log into another administrator account (or create a new one).

1. Log out of the target account.
2. Log in as an administrator.
3. Open Finder and navigate to /Users.
4. Right-click the folder to rename.
5. Select "Rename".

Changing Your Username

The Mac name (computer name/host name) differs from the username. To change your username:

1. Log out of the target account and log in as an administrator.
2. Open "System Settings" > "Users & Groups".
3. Control-click the username, select "Advanced Options".
4. Enter administrator credentials.
5. Modify the "Username" field (not "User").
