NullCPUPowerManagement

NullCPUPowerManagement disables Apple’s CPU power management by providing a null implementation. This is primarily for legacy systems that lack native CPU power management support. Modern Hackintosh builds using OpenCore typically do not need this kext.

Features

  • Null Implementation: Disables AppleIntelCPUPowerManagement
  • Kernel Panic Prevention: Prevents CPU power management-related kernel panics on unsupported hardware
  • Legacy Support: Designed for older systems without native CPU power management

Installation

  1. Download from GitHub or kext.me
  2. Copy NullCPUPowerManagement.kext to EFI/OC/Kexts/
  3. Add the kext to your config.plist under Kernel > Add
  4. Reboot your system

Important Note

Modern Hackintosh builds using OpenCore with proper SSDT generation (such as SSDT-PM or SSDT-XOSI) typically do not need this kext. It should only be used on legacy systems where proper CPU power management cannot be achieved through other means.
