Rename your Mac with Terminalįor those that are comfortable with the command line, you may use Terminal to set a different name for your Mac.Ģ) Type in the following command, making sure to replace YourNewComputerName with the name you want to set. On macOS Monterey and earlierġ) In the menu bar, go to  > System Preferences.ģ) In the Computer Name box, type in the name you want to use for your computer.Ĥ) Close the window, and you’re done. These steps will work to change your Mac device name, no matter what Mac you’re using (iMac, MacBook, MacBook Pro, Mac Pro, Mac mini, Mac Studio, etc.) On macOS Ventura and laterġ) Click the Apple icon () and choose System Settings.Ĥ) Add the new name in the Name field. If not, I’ll show you how to do just that.

The steps to set or change your Mac’s name are quick and easy, but I figured that if you already know how to do it, maybe this post will be a reminder for you to check that your Mac has indeed been given a name that makes sense to you. I wasn’t sure how that happened, but I knew I wanted to have a proper name for it just so I could recognize it when looking for it on the local network or when sharing files and documents with it over AirDrop. When in Find My iPhone, it would just show up as Unknown. While working on a series of posts about Find My iPhone, I realized that my iMac didn’t have a specific Computer Name attached to it. nmap -sU -p161 -script snmp-interfaces.Changing the Computer Name of your Mac is a great way to not only personalize it but, more importantly, to easily locate it within a network when multiple other Macs are present. In some cases you might also get the hostname from SNMP using the snmp-interfaces script but that will require UDP port 161 to be open. Or you can just run the specific nbstat.nse script and gain time and effort. Don't expect to get the hostnames of all the machines that you scan.

You can use a service discovery scan since it will execute several scripts(one of which is nbstat.nse) and will return hostnames. There is a wealth of parameters but each serves a special purpose. This is basically what you need to answer your question and get what you wanted. As root, you run Syn and don't have to finish the 3-way handshake. To see hostnames and MAC addresses also, then run this as root otherwise all the scans will run as a non-privileged user and all scans will have to do a TCP Connect (complete 3-way handshake) to get something. Use ifconfig for this and use regexp to clean the results Since there is no given IP for the LAN we could assume it is 192.168 but that's not always the case, so the first thing is to discover our IP address and our subnet mask. Nmap finished: 256 IP addresses (256 hosts up) scanned in 7.491 seconds
