Hey guys! Today I have a guide on fixing the "Your device or computer could not be verified. Contact support for assistance." error.


This applies ONLY to clover. There are fixes all over youtube about the same issue on chameleon branches.


Step 1. Download the file: HERE


Step 2. Open the downloaded EFI Studio App




Step 3. Go to "Select Device" and choose "Ethernet"




Step 4. Click "Add Device" grab the window that popped up.




Step 5. On that window, click on "write to com.apple.Boot.plist"


Step 6. Enter your admin password and let it sit for a few seconds and then close the EFI Studio application.


There! Your set! Now remember, if that didn't fix it, use steps 7-10  (Note: When doing steps 7-10 you must STILL DO THE ABOVE METHOD)





(No harm if you do this, just why waste time if it's already working?)


Step 7. Download Clover Configurator: HERE


Step 8: Open clover configurator and mount the boot drive.(If needed)


Step 9: Go to the ACPI tab


Step 10: Check FixLAN under fixes


Now your set! This guide is only for those on clover boot loader using Ethernet

I used chameleonlist in Maverick to change sbios to Mac pro 3.1. 

I recommend that  members restore a Maverick img to a usb harddrive to use to modify.

I have Maverick running fine from 250g yalway usb.

      hi so I recently upgrade to an Nvidia GT 730 (did an upgrade without needing a new PSU) the graphics card is detected by Mojave but no sound via the hdmi port I read Nvidia is forbidden to make web drivers past High Sierra (must be approved by apple) so how will I go about enabling sound through my HDMI (any additional info/files I'll be happy to supply)

      Hey I finally got OSX kinda to work. But when I boot with all settings enabled to make HDMI work I only get 10MB VRAM, I already tried changing all the FakeID but all give the same result or make it unable to boot at all. When I don't use any settings in the config.plist and boot without WhateverGreen and Lilu it works fine over VGA with 1500 something MB VRAM. But I need to work over HDMI..

      I also used another kext I saw someone else using on the 8th gen coffee lake CPU but it didn't have any effect aswel.

      I included my EFI Folder as download in this post, hopefully someone knows how to solve this because I've been searching for hours without luck
