## # What this SSDT does

The purpose of SSDT-PLUG is to allow the kernel's XCPM(XNU's CPU Power Management) to manage our CPU's power management. It's pretty self explanatory why you'd want this.

Note: SSDT-PLUG is only compatible with Intel's Haswell and newer CPUs, Sandy Bridge and Ivy Bridge will need to follow the ssdtPRgen method
(opens new window)(in post-install) while AMD users should not use this(unless attempting to attach AGPM which is outside the scope of Dortania's guides)

- Ivy Bridge-E(HEDT/server) however is supported by XCPM

## # Methods to make this SSDT

For SSDT-PLUG, there are 3 methods you can choose from:

- Prebuilt
- SSDTTime
- Manual
