I have trouble to install new produced KEXT file.
I made upgrade OSX to Hi Sierra and place new XFX RADEON VEGA 56 in to MAC PRO 5.1 dual processor system,
It works now, but fans run on 3200 rpm.
I found soft control software VGTab_en.app which produce KEXT file for remote the speed of fans. Many users used it successfully.
Not me :-( because I have trouble to initialize KEXT.
I used commands:
/ sudo kextload -b /library/Extensions/nameoffile.kext
It do not work and produce this error:
“failed to load - (libkern/kext) not found; check the system/kernel logs for errors or try kextulit(8)”
also I try place and run KEXT in the folder /System/Library/Extension , but same result.
Second way to install I used commands:
sudo su Password:
cp -R /System/Library/Extensions/VegaTab_56.kext /Backup\ Extensions
rm -R /System/Library/Extensions/VegaTab_56.kext
cp -R /Users/PattyHDesktop/VegaTab_56.kext /System/Library/Extension </Desktop/VegaTab_56.kext /System/Library/Extensions
chown -R root:wheel /System/Library/Extensions/VegaTab_56.kext
chmod -R 755 /System/Library/Extensions/VegaTab_56.kext
Result is same, when I run procedure to check for running external KEXT, the VEGA56 kext missing. And of course fans on VEGA56 run so high.
kextstat | grep -v com.apple
I checked privileges for file also, All users can read and write, except Guest.
Can you help me, please?
What is wrong?
I know about differences applied to HI Sierra for safety button in Security pane, but the button do not apear here.
I think problem is that something missing :-) not security, now.
