VoodooTSCSync

VoodooTSCSync synchronizes the TSC (Time Stamp Counter) across CPU cores on Intel processors, fixing kernel panics on multi-core systems.

When to Use

Typically only required for:

  • Intel Sandy Bridge (2011 socket) and older
  • Systems with TSC synchronization issues
  • Multi-processor configurations

Installation

  1. Download from Bitbucket
  2. Copy VoodooTSCSync.kext to EFI/OC/Kexts/
  3. Configure the core count in the kext’s Info.plist if needed

FAQ

Do I need VoodooTSCSync?

Only if you’re experiencing TSC-related kernel panics. Most modern Intel systems don’t need it.

Companion Tools

VoodooTSCSync Configurator

Legacy Tool

VoodooTSCSync Configurator is a 2017-era utility and may not work on modern macOS versions. For modern systems, use CpuTscSync instead — it's a Lilu plugin that handles TSC synchronization automatically without manual configuration.

VoodooTSCSync Configurator is a macOS app that lets you create custom versions of VoodooTSCSync for your specific CPU. It includes templates for common CPU models and allows you to specify the number of cores manually.
