VoltageShift VS ComboJack

I own a 2015 MacBook Pro 13", and do not plan on purchasing a new MacBook soon. I recently searched for how to improve battery life, and accidentally stumbled upon undervolting when I forgot to add "mac" at the end of my search. My curiosity was piqued, and I looked into it more. It turns out that there is one tool for undervolting a Mac, called voltageshift. It can be found on Github here, and is written by siscreative, abn5x, ridvan-cln, Artoria2e5, and Charlyo.

After downloading it here, extract the .zip and then navigate to the folder in terminal.

Additionally, I did undervolt CPU & GPU to reduce the heat a bit and save some battery with VoltageShift (it’s still not good though, I get like 4 hours of SoT total.)

Begin by following the existing undervolt guide https://github.com/sicreative/VoltageShift and extract the bios and search for two values: CFG Lock and Overclocking Lock

Setup This needs you to install VoltageShift (find on GitHub) to your System with your preferred settings, create two Shortcuts and Save.

Yeah, I gotcha what you're trying to do though the official method for the said action was using the VoltageShift (https://github.com/sicreative/VoltageShift). So with it you'd build a launch daemon to start things up with the appropriate parameters. But just brainstorming upon your particular set of issues, I think you should maybe look into rebuilding your PM settings in the exact same way you generate the pmset upon building up the new machine. Which means deleting the two pmset files and letting macOS generate the new ones upon the restart, which, in whole honesty, might be the culprit seeing how the CPU has changed in the meantime and it could be the culprit. Obviously this is just an in-theory post but nevertheless something I'd look into.

This solution, just like in Windows, is unfortunately not permanent and will have to be applied on boot, and every time you wake the computer from sleep or hibernation. We will be using the latest release of VoltageShift, an Open-source software that allows us to modify MSR and undervolt. Do note that this only works on Haswell machines and newer. There's a chance you could use CPUTune or other software that is able to write to MSR values directly, but this guide exclusively focuses on VoltageShift.

As u/xartic1 mentioned, you can use volta or if you don't want to pay, you can use the library used by volta underneath - https://github.com/sicreative/VoltageShift

Headphone audio output and input (wired and Bluetooth headphones) ComboJack

I tried all of the layouts that are created for ALC255 and NONE of them worked properly (getting no sound from speakers and/or headphones, getting static noise from the headphones, or the sound not working properly after sleep, …) so I went on to create my own layout from scratch; got my codec-dump and its visual graph, noted audio nodes and possible node-mixer connections, compiled AppleALC after every change I made, and I did this process to get audio from any source for 9000 times. I can say that it wasn’t pleasant. At all. Even the layout I created specifically for this laptop still does not work properly, headset mic is still not working and I need ComboJack fix to get audio from headphones/headset after sleep. At least internal mics and headphones/headsets work now.

This one? https://github.com/hackintosh-stuff/ComboJack

I assume that your laptop has a combined jack, so you can try this. Or another one that I'm currently using is ALC Fix app, can't find its origin so I uploaded mine on Google Drive. Personally I prefer the second one because it just do its job in background, while the first one always ask you what did you plug in. Hope that will help you!

Thanks. I'm using this https://github.com/hackintosh-stuff/ComboJack with layout-id 5. Its made for ALC256/257 and we both have 256. However CleanMyMac reports this as CoinMiner, but that's the only solution that works for me.

Have you tried this ?

As for the headphone jack, I used Combo Jack: https://github.com/hackintosh-stuff/ComboJack. It helped with mine

I just read your github, I found this a few days ago to fix headphone jack on my Latitude, I think it should be working on your laptop too https://github.com/hackintosh-stuff/ComboJack
