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

[It worked for me]

Hi. Well for those who been having problems with some apps, hanging/not working, i found that when some apps start (like itunes SRS iWow for example) hangs with no specific errors (in this case itunes hangs), but looking in the console i saw someting like “GetHostUUIDString: unable to determine UUID for host. Error: 35″ that some apps reports time to time and then they hang; so well the problem appears to be something about IEEE80211 wireless that some how osx looks for??… anyway, i found that adding a config for that into the NetworkInterfaces this problem get solved!
You need to go to /Library/Preferences/SystemConfiguration and edit NetworkInterfaces.plist and add a new dict with the IEEE80211 config..
<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>
Save and reboot… After i did this, the problem got solved and all the broken apps and games starting working….
