UXTU4Unix (Work-in-Progress)

Powered by RyzenAdj and Python

Caution

Caution: Avoid using UXTU4Unix in conjunction with SMCAMDProcessor due to potential conflicts.
This project does not serve as an alternative to SMCAMDProcessor, NootedRed, or AMDPlatformPlugin for CPU/APU power management.

Supported APU & Operating Systems

Note

Compatible with AMD Ryzen APUs supported by either NootedRed or the Premade Preset section in UXTU (or generally supported by RyzenAdj).
Operating Systems: macOS 10.9 through 15, and Linux (tested on Debian-based distributions, Fedora, AlmaLinux, Alpine, Arch, CentOS, Mint, openSUSE, Pop!_OS, RHEL, Rocky, Stream, SUSE).

Usage Instructions

Disable Secure Boot in the BIOS. (Unknown: Applying the Secure Boot certificate to UEFI may enable compatibility.)
Download the official build from the Releases.
Run UXTU4Unix.command (macOS only) or run UXTU4Unix.py using the command: python3 /path/to/UXTU4Unix.py or python /path/to/UXTU4Unix.py.
Follow the on-screen instructions.
[macOS only] For enhanced temperature management and control with UXTU4Unix, disable Core Performance Boost in the BIOS using Smokeless_UMAF. Note that this may significantly reduce CPU performance, as the Core Performance Boost feature on macOS is not optimal.

Frequently Asked Questions

1. Why is SIP disabled in macOS?

The binaries (ryzenAdj and DirectHW) are flagged as untrusted kexts in macOS. To ensure functionality, it is necessary to disable SIP and include the ALLOW_UNTRUSTED_KEXTS flag (0x1).

2. Why does `UXTU4Unix` lack comprehensive CPU support?

During the transition of AMD APU presets from UXTU to UXTU4Unix, some commands were incompatible with ryzenAdj. UXTU employs various methods to modify CPU/APU settings beyond those supported by ryzenAdj, particularly concerning CPU presets. Consequently, only select commands were retained as workarounds.

3. What is the timeline for the GUI?

The release of the GUI is forthcoming, as communicated by NotchApple1703.
