Devices that you connect to your network will usually have a way that they are identified. Sometimes this method of identification is automatic and very difficult to change but, other times, it is relatively easy to change the name of a device. For example, if you want to change your MacBook Air’s computer name, then it’s a relatively short process.
Our tutorial below will show you which menu contains the information that you need to modify when changing your computer’s name on a MacBook Air. This is ideal if you have multiple similar devices on a network that are difficult to identify from one another, or if the default name given to the MacBook Air is inaccurate or unhelpful.
How to Rename a MacBook Air
The steps in this article were performed on a MacBook Air using the MacOS High Sierra operating system. By completing the steps in this guide you will be changing the way that your Mac is identified to other devices on your network. Additionally this will not affect any of the usernames on the computer.
If you are an iPhone owner and want to change the name of that device, too, then you can follow our guide here to make that switch.
Step 1: Click the System Preferences button.
Step 2: Click the Sharing button.
Step 3: Click inside the Computer Name field at the top of the window, delete the existing name, enter the new name, then press Enter on your keyboard.
Note that the computer name only serves to identify the device when you are connected to a network, as it is how other devices and computers on the network will see you.
If you need to change any of the sharing options on your computer, then they may be found on this menu. This includes things like remote access and remote management, or printer sharing. If anything like this is something that you have been looking for a way to do, simply look at the list at the bottom of this sharing menu and see if you want to turn anything on.
