不知这可不可以解决，e文不太好没敢试！0. Uninstall Korg Legacy and delete all plist files and preferences related to Korg Legacy
in User/L/P/
1 . You have correctly injected the Ethernet Hex into your com.apple.Boot.plist, (make sure you are editing the plist in the correct location (/Extra) if you are using chameleon/iHack) or you have added <key>EthernetBuiltIn</key><string>Yes</string> to your com.apple.Boot.plist (I didn't need the injection the string was fine)
2 . You have IONetworkingFamily.kext correctly installed in S/L/E/
3. You have repaired and touched the folder S/L/E/ using Terminal
chmod -R 755 /System/Library/Extensions/
chown -R root:wheel /System/Library/Extensions/
touch /System/Library/Extensions
4. go to System Preferences > Network and delete all the network connections on the left hand bar using the - button
