I FINALLY got this working!

 

Here's what you do:

1. cd to System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleIntel8255x.kext/Contents/

2. add this: 0x27dc8086 to the <string> line below <key>IOPCIMatch</key> in Info.plist

3. cd back to System/Library/Extensions/IONetworkingFamily.kext and move or rename AppleIntel8254XEthernet.kext

4. delete Extensions.mkexts from System/Library and rebuild kext cache (kextcache -k /System/Library/Extensions/)

5. repair permissions and reboot

 

Note: please read these threads to understand which types of 82562v NIC's will work with this fix:

Enjoy!!

Help me a little guys!

 

Here is exactly what I did so far (in terminal):

 

open /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleIntel8255x.kext/Contents/Info.plist

then I edit the file, adding " 0x27dc8086" after all the other hex (is this correct)

then I save, but it says I don't have permission to edit the file...

 

Sooo, how do I edit this file??? I tried in linux too, but I didn't have permission to save the file..

 

cd doesnt seem to change directory for me, my directory stays at the default directory for my user in Terminal...

open /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleIntel8255x.kext/Contents/Info.plist

then I edit the file, adding " 0x27dc8086" after all the other hex (is this correct)

then I save, but it says I don't have permission to edit the file...

 

You are making the correct edit. However, to work with system files you must su to root:

sudo -s [password]

sudo [command]

e.g.: sudo nano info.plist

 

To verify ownership and permissions:

ls -al

To set ownership and permissions:

sudo chown root:wheel <file name>

sudo chmod 755 <file name>

 

Or, for good measure, try diskutil:

sudo diskutil repairPermissions /
