How to fix superduper error: CFGetHostUUIDString: unable to determine UUID for host

January 3rd, 2010

When running superduper, I encountered this error. According to direction from netkas forum, here is how to fix it.

Edit /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

Changes <dict> section to:

^?View Code TEXT

		<dict>
			<key>BSD Name</key>
			<string>en3</string>
			<key>IOBuiltin</key>
			<false/>
			<key>IOInterfaceType</key>
			<integer>6</integer>
			<key>IOInterfaceUnit</key>
			<integer>3</integer>
			<key>IOLocation</key>
			<string></string>
			<key>IOMACAddress</key>
			<data>
			ABbPoF5V
			</data>
			<key>IOPathMatch</key>
			<string>IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/P0P3@1C,2/
	      IOPCI2PCIBridge/pci14e4,4311@0/AirPort_Brcm43xx/IO80211Interface</string>
			<key>SCNetworkInterfaceType</key>
			<string>IEEE80211</string>
		</dict>

Then reboot.
“CFGetHostUUIDString: unable to determine UUID for host” error will be eliminated

Now superduper work very well.
