I’m on MacOS 15.1, and wish to change the identify my MacBook broadcasts to the community. My MacBooks identify is MyNames-Macbook-`professional in Settings > Basic > About > Title and the identical in Basic > Sharing > Native hostname with the extra .native. I would like this (or one thing related) to be the community identify, i.e. if I attempt to arp -a from one other machine I get mac (I-address) …, extra importantly, the file sharing identify below smb://mac. Each of those are listed as “mac” and does not appears to alter after I change the identify wherever. At one level it modified to my ip tackle after I restarted the router, nevertheless it returned to “mac” on a system reboot.

I noticed somebody recommend to alter the wifi WINS NetBIOS identify, which was “MAC”, so I modified this to the identical identify as my pc identify which didn’t remedy my subject. Moreover somebody recommended altering the identify in About, and ready for a DNS refresh, can this be pressured on my router, or simply by way of a router restart?

I used to be in a position to obtain this outcome on my outdated MacBook by altering the identify, and whereas it did not change instantly however after a couple of days, the unique identify was the identical identify because the machine identify. So hopefully it would work itself out and I can simply shut this off for the subsequent particular person wanting, however within the meantime does anybody know a greater repair for this.
