[SOLVED] E7450: LAN issue on El Capitan

[acquarius.13]

Hi everybody,

 

I successfully installed El Capitan on a E7450 as in my signature following the guide posted by Jake Lo https://osxlatitude.com/index.php?/topic/8514-dell-latitude-e7450-clover-uefi-only/&do=findComment&comment=54665

 

Following the guide, I was able to accomplish all the points apart auto SMBios and SSDT generation.

As the subject of my topic I cannot make the LAN working. From windows the LAN adapter is named as Intel Ethernet connection I1218-LM

While waiting for the new WLAN card, is there anything I can do to make the LAN to work?

 

Thank you so much in advance

Thank you Hervé!

 

Sorry..before I forgot to mention that I already tried to install Mausi kext via kext installer but no way..

[Hervé]

Then install it manually:

1. copy the kext to /Library/Extensions
2. repair permissions and rebuild your cache:

sudo chmod -Rf 755 /L*/E*
sudo chown -Rf 0:0 /L*/E*
sudo touch -f /L*/E*
sudo kextcache -Boot -U /

If you obtain an error message "....77", repeat the touch + kextcache commands.

Disable or enable Legacy Rom Option in the BIOS.

@Hervé: Nothing good even with that procedure, that gave no errors

 

@Jake Lo: If I disable legacy boot room I get corrupted display

 

     

[Jake Lo]

Did you set the DVMT with EFI shell or use Clover patch?

[acquarius.13]

I used the EFI shell, as reported into the guide

[Jake Lo]

Does the disabling enable your ethernet?

Try re-enabling to see if Ethernet still work.

Mine works fine with it enabled.

I've just tried to disable legacy boot, but when I do that, graphic is corrupted and I can see only stripes on the screen...so I cannot know if ethernet is enabled!
