How to change computer name in macOS
When your Mac is used in local network or when transferring files via AirDrop, you can find it in the device list only by name. If the computer name was set automatically, it may create some difficulties for its identification. In this case it is necessary to change the current device name to something more comprehensible. Today we'll show you how to do it.
Despite the fact that the name change process is quite simple, there are some limitations. For example, you cannot use special characters because other computers or devices can not display. Therefore, we recommend to choose a simple and short name for your Mac.
Launch "System settings". Next, go to the section "General access".
At the top the column "computer Name" you can specify the preferred name. Confirm your selection and close the window.
Setup is complete. Set the computer name will now be displayed when working with the local network, AirDrop, and when browsing the device in iCloud and Find My Mac.
