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](https://dortania.github.io/OpenCore-Post-Install/universal/pm.html#sandy-and-ivy-bridge-power-management)(in post-install) while AMD users should not use this(unless attempting to attach AGPM which is outside the scope of Dortania's guides) ## Methods to make this SSDT For SSDT-PLUG, there are 3 methods you can choose from: * [Prebuilt](/Universal/plug-methods/prebuilt.md) * [SSDTTime](/Universal/plug-methods/ssdttime.md) * [Manual](/Universal/plug-methods/manual.md)
