Once you exit the Sharing window, your computer’s hostname will automatically change to match your new computer name. The hostname is an address (your-Mac.local) that devices equipped with Apple’s Bonjour networking software use to recognize and connect to your computer.

Why should you change the name of your Mac?
There are several reasons why you might want to change the name of your Mac. If your computer is a hand-me-down, it might have the name of the previous owner on it and you probably want to change it to your name.
If your Mac has a non-descriptive name such as “computer” or no name at all, it may be hard to find it when you want to send or share files.
If you have more than one computer, each should have a name that clearly identifies it so that you can tell them apart. You might do this by naming them based on their model, such as “MacBook Air,” “iMac,” etc.
You might want to add your name, to differentiate your computer from others in your home that belong to other users. If multiple computers on your network have the same name, Apple will automatically add a number to the end of the name.
Best practice, however, is to give each Mac its own unique name.
