Hi guys, i edited the IONetworking thing to get FCP to work on my hackintosh, but now my yukon marvell ethernet port doesn't seem to work. May i know how to fix it?I've tried network diagnostics and checkde my configuration for the networking kext, but they are all the same from when i haven't edited the eth0/eth1 config in IONetworking. thanks for the help in advance!
