You no longer have to use Clover or HWPEnabler to enable HWP. If X86PlatformPlugin is loaded with a model identifier that supports HWP (MacBook9,1, MacBookPro13,x) the OS will enable HWP, and keep it enabled after sleep. Not only that, but the OS will dynamically manipulate the HWP request values depending on load and whether the system is on AC or battery.
