Browse files Browse the repository at this point in the history
Generated through modified CPUFriendFriend.py which instead of taking
Mac-DB15BD556843C820.plist from
/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources
will use third vector of Mac-9AE82516C7C6B903.plist i.e. MacBook9,1.
This model has a Skylake M7-6Y75 processor.
Data provided to CPUFriendFriend :
- Minimum Frequency : 800 MHz
- EPP : 80 hexa (balanced power)

Got excellent temperatures in Intel Power Gadget.
GeekBench 4 performances (Single-Core 4847, Multi-Core 13881) compare
very favorably with those previously recorded

I checked with AppleIntelInfo that, even after a sleep cycle, HWP remains
enabled https://github.com/Piker-Alpha/AppleIntelInfo
