_CFGetHostUUIDString: unable to determine UUID for host. Error: 35

1. /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist 수정

1.) BACKUP your /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
2.) Open /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
3.) ADD AFTER <string>Ethernet</string></dict> the following:
<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>

4.) IF you have more than 3 interfaces or there is an "en3" interface change it to "en4" or a higher number, don't forget to change this "<integer>3</integer>" to "<integer>4</integer>".
5.) You need to REBOOT
6.) If this work for you please tell me. 
7.) If this workaround did not work please provide your system.log and yourNetworkInterfaces.plist.

Why does this error happen?
Well at looking at the source code of the configd there is a plugin "InterfaceNamer" it seams the plugin will always skip interfaces 
that are IOBuiltin = false. The "<key>IOBuiltin</key>" cannot be changed because the plugin will check and restore it on next boot.
But it does not check if wireless interfaces <key>SCNetworkInterfaceType</key><string>IEEE80211</string> are IOBuiltin.
Like I say this is only a workaround and there will be more need of testing.

2. /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily 수정 

You can get it here.
Unpack it an place it to/System/Library/Extensions/IONetworkingFamily.kext/Contents/MasOS/
If you used my workaround please restore your backup of NetworkInterfaces.plist.

This fix will set IOBuiltin = true for all network devices.
