How do I avoid the hostname Macintosh-2?

  • 772

Whenever I join a network where there are other Macs, I sometimes get the notification:

This computer's local hostname Macintosh.local is already in use on this network. The name has been changed to 'Macintosh-2.local`.

From then on the result of hostname is this changed name. I've tried:

  • System Preferences->Sharing->Computer Name.
  • sudo hostname jared-mac.
  • Modified /etc/hostname.
  • System Preferences->Network->Advanced... ->TCP/IP DHCP Client ID
  • System Preferences->Network->Advanced... ->WINS

Is this a known issue? Or am I doing something wrong?

mac-osx hostname

    Normally the two are in sync, but you can alter the hostname by going to:

    System Preferences -> Sharing -> Under Computer Name on the right side is an Edit button. Click the Edit button and in the new sheet alter your hostname to match your computer name.
