UXTU4Unix (Work-in-Progress)

Powered by RyzenAdj and Python

![GitHub Downloads (all assets, latest release)](https://img.shields.io/github/downloads/AppleOSX/UXTU4Mac/total) --- > [!WARNING] > - With the end of Hackintosh support in macOS 26 Tahoe, UXTU4Unix `v0.3.4` will be the last version to support macOS. After that, we will shift our focus solely to Linux until `UXTU` officially supports Linux. > [!CAUTION] > - **Caution:** Avoid using `UXTU4Unix` in conjunction with [SMCAMDProcessor](https://github.com/trulyspinach/SMCAMDProcessor) due to potential conflicts. > - This project does not serve as an alternative to [SMCAMDProcessor](https://github.com/trulyspinach/SMCAMDProcessor), [NootedRed](https://github.com/ChefKissInc/NootedRed), or [AMDPlatformPlugin](https://github.com/ChefKissInc/AMDPlatformPlugin/) for CPU/APU power management. ### Supported APU & Operating Systems > [!NOTE] > - Compatible with AMD Ryzen APUs supported by either [NootedRed](https://github.com/ChefKissInc/NootedRed) or the **Premade Preset** section in [UXTU](https://github.com/JamesCJ60/Universal-x86-Tuning-Utility) (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](https://github.com/AppleOSX/UXTU4Unix/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](https://github.com/DavidS95/Smokeless_UMAF). Note that this may significantly reduce CPU performance, as the `Core Performance Boost` feature on macOS is not optimal. ### Fixing Python Certificates on macOS

## 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. ## Advanced Users For more detailed configurations, please refer to [Custom.md](Custom.md). ## Preview
