Run this command in Terminal:

sudo scutil --set HostName Daniel-MM.moranit.local

This is what it looked like for me:

But that’s not all… all that does is change the name when you type “hostname” at a terminal window…

What if you want to change it and your using BigFix or something like that…

Go to Applications->System Preferences->Sharing

change the “Computer Name” field to the desired value

also click “Edit” and change that too…

Then your all done.
