skx Posted January 30, 2010 Share Posted January 30, 2010 Alright, so I've been really happy with my GA-EP45-UD3R now for a while. Today I want to use Time Machine and the error rears its head: "Unable to find built-in ethernet" Now--I've had ethernet working forever--but I guess it hasn't been legitimately recognized as built-in ethernet. I've done the DSDT patching, I've used RealtekR1000.kext, I've tried setting EthernetBuiltIn=yes in my com.apple.Boot.plist, I've added the EFI string to my com.apple.Boot.plist. Every possible thread and post I could find on the subject--I've tried! NOTHING WORKS. PLEASE help!!!!
