What’s in a name? Well, let’s see:
Mac-mini:~ user1$ echo $PS1 \h:\W \u\$ Mac-mini:~ user1$ export PS1="[\H] " [Mac-mini.local] scutil --get ComputerName Mac mini [Mac-mini.local] scutil --get LocalHostName Mac-mini [Mac-mini.local] scutil --get HostName HostName: not set [Mac-mini.local] hostname Mac-mini.local
By the way, do you know what happens to your Time Machine if you change your hostname?
