CpuTscSync

CpuTscSync is a Lilu plugin that combines the functionality of VoodooTSCSync and disables xcpm_urgency for proper Time Stamp Counter synchronization on multi-core Intel processors.

Overview

The Time Stamp Counter (TSC) is a hardware register that counts CPU cycles since boot. On multi-core Intel processors, TSC values can drift between cores, causing timing issues, kernel panics, and unstable system behavior. CpuTscSync synchronizes the TSC across all CPU cores and disables the xcpm_urgency timer, which can cause issues on some Hackintosh configurations.

Features

• TSC Synchronization: Syncs Time Stamp Counter across all CPU cores
• VoodooTSCSync Replacement: Combines and improves upon VoodooTSCSync functionality
• xcpm_urgency Disable: Prevents xcpm_urgency timer issues
• Kernel Panic Prevention: Fixes timing-related kernel panics on multi-core systems
• Lilu Integration: Built on the Lilu patching framework

Installation

1. Install Lilu first
2. Download the latest release from GitHub
3. Copy CpuTscSync.kext to EFI/OC/Kexts/
4. Add the kext to your config.plist under Kernel > Add
5. Ensure Lilu is loaded before CpuTscSync
6. Reboot your system
