Setting the Hostname on macOS

For my work laptop on macOS 12.6 Monterey. Assume the hostname is dobby.ether.

A simple sudo hostname dobby did not persist the hostname across sessions or reboots; it kept resetting to MacBook-Pro. I don’t know if this was some policy pushed out or because of weirdness with macOS itself.


# This did not exist
sudo vim /etc/hostconfig

# I added this line

This did not work. YMMV.


scutil --set LocalHostName rheya
scutil --set HostName rheya.ether

Enter the password when asked. This should work.
