How do I change my Mac's Bluetooth name?

Your Mac's Bluetooth name is visible to all and sundry, and by default includes your name and the type of Mac you own. For various reasons you might not want it to include this information - or you might want to include a witty joke, as some people do with their Wi-Fi routers.

In any case, it's very straightforward to change your Mac's Bluetooth name, although the option where you change this is hidden in a section of System Preferences where you might not have thought to look. It isn't under the Bluetooth section. Here's how to give your Mac a new Bluetooth name.

Oddly enough, if you want to pick a new Bluetooth name for your keyboard, mouse or trackpad, you do change this via the Bluetooth section of System Preferences.

Open System Preferences and select Bluetooth - it's just to the left of the Sharing icon on the third row. Look for the device whose name you want to change: Right-click (or Ctrl-click, if you've not got a right-click on your mouse) the device's name, select Rename, then type a new name. Click Rename again. (This only works on devices that you've paired with, for obvious reasons.)
