Hi,
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.
"Fan Speed(%)"=65"Fan Speed(RPM)"=3206"Temperature(C)"=30“Total Power(W)"=46I 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\ Extensionsrm -R /System/Library/Extensions/VegaTab_56.kextcp -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.kextchmod -R 755 /System/Library/Extensions/VegaTab_56.kexttouch /System/Library/Extensionsexit
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.appleI 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.Thank you.
