Many Mac users tend to keep the default name of their device and may never consider changing it. Many people choose to stick with the name from the initial setup, such as "Johnny's MacBook Air" or simply "iMac."

Learning how to change the name of a Mac is a very practical skill, especially when you have multiple devices, as it can help you quickly distinguish and manage them.

Next, we will teach you step by step how to change the computer name, host name and Bonjour name (local host name) in macOS system.

Why change the name of your Mac?

Modifying the name of your Mac can not only show your personality, but also help improve your user experience:

• Personalize your Mac: The default name may not be to your taste. Changing it to a name you like can make your Mac more personalized.
• Optimize the AirDrop experience: AirDrop is a convenient file transfer function in macOS, but if the Mac name is not intuitive enough, others may be confused when sending or receiving files. A clear and concise name makes device identification simple.
• Simplify Bluetooth connections: If your Mac name is too complex, it may be difficult to distinguish Bluetooth devices when connected. Simple and clear names facilitate quick pairing.
• Enhanced system interaction experience: In the file system and terminal commands, an easily identifiable name can make your operations more convenient.
• Improve network management efficiency: On a home network, an easily identifiable Mac name helps with device management and troubleshooting.

The difference between computer name, host name and Bonjour name

Before changing the name of your Mac, you need to understand the basic concepts of computer name, host name, and Bonjour name (local host name) in order to manage your device more effectively.

For example, if your Mac computer name is Billyfus-MacBook-Pro, then the local host name (Bonjour name) is Billyfus-MacBook-Pro.local, which is convenient for local Identify and connect within the network.
