CPUTune on MacOS BigSur Beta 10

[abarsotini]

Hi,

Is it possible to use CPUTune on MacOS BigSur Beta 10?

Is there a version of CPUTune already compiled for Download, Or some kind of tutorial on how to compile the source code by XCODE?

Tks.

Have you tested the extension with Big Sur?

[abarsotini]

yes, it doesn't work...

[nimamox]

Thanks. Did you go through all the steps, disabling csrutile and removing IOPlatformPluginFamily.kext? Could you elaborate on what the problem is? Can it even be loaded with kextload? Do you get a kernel panic?

Where can I find these instructions?

does it work for Big Sur?

Cannot remove IOPlatformPluginFamily.kext using the steps in https://portugnole.blogspot.com/2020/05/running-macbook-without-battery-lets-go.html, the CPU always runs under 800MHz in BigSur.

Remove IOPlatformPluginFamily.kext by following the instructions below:

And instead of CPUTune use VoltageShift. For me the commands are:

$ ./voltageshift loadkext
$ ./voltageshift turbo 0
$ ./voltageshift write 0x1FC 0x04005e

Thanks a lot. Just wonder what MSR register 0x1FC and value 0x04005e are.
