maybe because kext loading was failed
try to kextload manually

Thanks, but it does not work, here are the outputs:

sudo kextload ./VoltageShift.kext
 failed to load - (libkern/kext) link error; check the system/kernel logs for errors or try kextutil(8).

Then I follow the instruction,

sudo kextutil ./VoltageShift.kext

Any idea? Thanks! @kfur

Utilities > Terminal

csrutil enable --without kext

reboot to disable kext sign protection.

I did but it still doesn't work

[WoadZS]

@sicreative I have already disabled the SIP before

➜  ~ csrutil status

voltageshift.zip
from the log, i thing you are using before catalina 10.15, as i updated the kext target to 10.15, it may break the previous version support.
I will roll back to 10.12, please help check the attached file is usable and inform here, so i will update the code and package.

[WoadZS]

@sicreative Thank you so much, but the file is not working as well. Just the as same as before, ./voltageshift works but not with other extra commands, such as mon, info.
My OS version is 10.14.6, let me know if you need any other information that may helpful.

BTW, 1.20 works before, would mind attache 1.20 file so that I can check if there is anything wrong on my hackintosh.

Same issue here, in a Macbook Pro with 10.14.6:
So I tried to compile it locally (even changing targets, all good) BUT can't be loaded:

For x86_64:

3 symbols not found in any library kext:

__ZN9IOService8DispatchE5IORPC

[sicreative]

The kext should no change between version 1.2 and 1.22
here is previous complied file 1.20
voltageshift_1.2.zip

[kfur]

@munsuri @WoadZS if you are on macOS Mojave kext must be builded by xcode 10 due to SDK version

[munsuri]

@sicreative that last version, 1.20 works fine, thanks! I can toggle now the Turbo and limit the power Watts, great! Sadly the undervolting seems to have been locked in the Intels Apple uses now...
@kfur I only have xCode 11. But it compiled successfully... dunno why it complains about linkage just when loading...

[khoa-nv]

Doest anyone can set PL1 and PL2 with buildlaunchd? I used
sudo ./voltageshift buildlaunchd -160 0 -160 0 0 0 0 35 60 160
but it doesnt work??

I don't know why kext complied under Xcode 11 is not work on previous OSX, however you can use the latest voltage script together with 1.20 kext, just replace the kext to old one under some directory.

it should work. What message as show when you try?

  ./voltageshift power PL1 PL2

[khoa-nv]

This is message when I run command
./voltageshift power 35 60

when I run this command I get this message
sudo ./voltageshift buildlaunchd -160 0 -160 0 0 0 0 35 60 160

But after shutdown and login again, the PL1 and PL2 no change

Did I use it the wrong way?

Can you share your options and buildlaunchd command, please?

[kfur]

@khoa-nv show your /Library/LaunchDaemons/com.sicreative.VoltageShift.plist file

@khoa-nv show your /Library/LaunchDaemons/com.sicreative.VoltageShift.plist file

Here bro, this is the file content:

I'm using this file

[sicreative]

please use the latest version if you want fix the PL1/PL2 when launch.

If you use 10.14 or before, replace the 1.2 kext and this should run.

Oh my god, thank you so much. I solved my problem. That problem because I did wrong way. Thank you so much again.

[WoadZS]

@sicreative thank you, as you mentioned, the best way to solve this is use the voltageshift script in 1.22 version and kext of 1.20?

We updated the download page for 10.14 or before.

Found this when searching for the message, sorry about the duplicate bug report. But when I tried version 1.2 the kext loads fine (manually with kextutil) but then "voltageshift info" crashes the system.
