How to Change the Computer Name on Your Mac

When you connect your Mac on a local network, it is identified by a unique name. For example, you can setup a local network at your home comprising of many different devices and each of them have a name and ID. In the case of Windows 10 PC, the name is something like Desktop-DG7C9IN where the last seven characters are selected at random during the installation of the operating system.

In case of Mac, things are much simpler and the computer’s name is automatically set to be the user’s computer where user is the username of the Mac user. This username was set when you first started your Mac and created a user account. If you don’t want to reveal your username to anyone on the network or if you want to pick a more interesting computer name for your Mac then, you can easily change it.

Here is how you can change the computer name on Mac:

  1. Click on the Apple logo icon near the top-left corner to open the Apple menu.
  2. From the Apple menu, select System Preferences. Change Computer Name on Mac
  3. When System Preferences opens up, click on Sharing. Change Computer Name on Mac
  4. Unlock the preferences if they are locked which involves clicking on the small lock and entering your credentials. Without unlocking, any changes made to the preferences are not saved. After you have unlocked it, the lock icon changes and becomes “unlocked”.

    Changing the name(s) requires administrator access and you will be prompted for your credentials before any changes are made to your system.
