Hello, I'm using Macbook pro 16 inch 2019, after using sudo command in the screenshot (1), the voltage is still 0 mV. Can anyone help me? This is my first time using Macintosh and I've never use Hackintosh before.

Thank you everyone!!!

I'm using macOS Monterey and pretend to downgrade to Catalina, will it work on Catalina?

Hi I want to know what cpu temp does the voltageshift is showing when running the info flag? Because I use intel app and cannot find that temperature, I can say that because voltageshift gives 90+C temps while mine only shows 20-30C powermetrics.

Your firmware update when you ran Monterey would have locked the register to which the undervolts apply. If this is the case you will need to modify your firmware with a physical programmer as explained below:

I just did this and can confirm it works with version 478.0.0.0 (latest Big Sur). Which firmware version is running on yours?
