Apple - Computer name keeps changing OSX 10.10 (14A389)

Go to Macintosh HD > Library > Preferences > SystemConfiguration and delete the following files:

  • com.apple.airport.preferences.plist
  • NetworkInterfaces.plist
  • preferences.plist

Then reboot the Mac.

The host names should be recreated correctly.

(According to http://forums.imore.com/os-x-yosemite-10-10/304804-my-computer-name-changing-10-10-a.html these are instructions provided by an Apple tech.)


To be able to achieve this, run the following commands on the terminal:

sudo /usr/libexec/PlistBuddy -c "Add :ProgramArguments: string --no-namechange" /System/Library/LaunchDaemons/com.apple.discoveryd.plist

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

and 

sudo scutil --set ComputerName <host-name-U-want>
sudo scutil --set HostName <host-name-U-want>
sudo scutil --set LocalHostName <host-name-U-want>
hostname -f

This solved it for me:

Go to System Preferences -> Energy Saver. Select "Power Adapter" and then uncheck "Wake for network access".

Ever since I did that a couple of days ago my computer name has stayed the same.
