Adjust power management settings for AMD Ryzen APUs, Universal x86 Tuning Utility for Hackintosh/macOS and Linux

UXTU4Unix (WIP)

Based on RyzenAdj and Python

---

Caution

• Do not use UXTU4Unix with SMCAMDProcessor as they may conflict with each other.
• This is not an alternative solution to SMCAMDProcessor, NootedRed and AMDPlatformPlugin for their CPU/APU power management itself.

Supported APU & OS

Note

• AMD Ryzen APUs processors that are supported by either NootedRed or the Premade Preset section in UXTU (or simply supported by RyzenAdj) are detailed below.
• Support ranges from macOS 10.4 to the latest version (14).
• Linux is supported (tested on Debian-based distros, Fedora).

Supported APU Codenames
Raven
Picasso
Renoir
Cezanne
Dali
Lucienne
Van Gogh
Rembrandt
Phoenix Point
Hawk Point
Strix Point

• If your APU doesn't appear on this chart or if it's a demo CPU/APU, then it may work with only Custom mode.

Usage

• Download the official build from Releases
• Run UXTU4Unix.command (only for macOS) or run UXTU4Unix.py by using python3 command ( python3 /path/to/UXTU4Unix.py )
• Follow the instructions.
• [macOS only] Disable Core Performance Boost in BIOS using Smokeless_UMAF to achieve better temperature and better control with UXTU4Unix but sacrifice a lot of CPU performance

FAQ

1. Why do we have to disable SIP in macOS?

• Honestly, the binary file (ryzenAdj and DirectHW) is recognized in macOS as untrusted kexts. So, in order to get it working, we have to disable SIP including the flag ALLOW_UNTRUSTED_KEXTS (0x1).

2. Why does UXTU4Unix lack CPU support?

• When I ported a bunch of AMD APU presets from UXTU to UXTU4Unix, some commands were not compatible with ryzenAdj (because UXTU uses lots of methods to change CPU/APU settings besides ryzenAdj), especially the CPU presets. So, I could only keep some commands as a work-around.

3. GUI wen eta?

• idk - NotchApple1703 said to me, but we will release it soon.

Caution

• We think the members and owners of ChefKiss Inc shouldn't use this tool. Why? Because Visual will say Do not use this tool because it will break our NootedRed/AMDPlatformPlugin power management, etc.... So, is that true? We still don't know because I've been banned from both Telegram and GitHub by ChefKiss (Visual)
• PR is welcome btw

Special thanks to

• b00t0x for the guide to build ryzenAdj based on DirectHW and pciutils-osx
• JamesCJ60 for UXTU
• corpnewt for command file
• NotchApple1703 for the GUI (starting from version 0.3.x or 0.4.x)
