[Unofficial] v15.7 beta3 with Broadwell CPUs support

Note: This is NOT an official release of Pike’s

After reading Pike’s codes, I manually injected new Board-IDs and Broadwell CPUs data.

So now you can use to create a custom CpuPm SSDT and make power management work properly.

(i.e. X86Platform.kext and X86PlatformShim.kext will be loaded; IOPPF: XCPM Mode can be found in

The following Broadwell CPUs are now supported by v15.7 beta3:

# Intel Core M series
Core M-5Y10
Core M-5Y10a
Core M-5Y10c
Core M-5Y31
Core M-5Y51
Core M-5Y70
Core M-5Y71

# 5th Intel Core i3 ULT series

# 5th Intel Core i5 ULT series

# 5th Intel Core i7 ULT series

The following new Board-IDs are now supported by v15.7 beta3:

Mac-9F18E312C5C2BF0B MacBookAir7,1 (Early 2015)
Mac-937CB26E2E02BB01 MacBookAir7,2 (Early 2015)
Mac-BE0E8AC46FE800CC MacBook8,1 (Early 2015)
Mac-E43C1C25D4880AD6 MacBookPro12,1 (Early 2015)
Mac-F305150B0C7DEEEF MacBook8,2 (Early 2015)


Essential Data: ssdtPRGenEssentials

Extract the archive and copy the folder named ssdtPRGen to ~/Library (i.e. /Users/YOURUSERNAME/Library)

And then here is the main script:

You need to modify the permission of this script if necessary. (chmod u+x

Test result

This script was tested on Intel Core i5-5200U, and X86Platform.kext & X86PlatformShim.kext were loaded; IOPPF: XCPM Mode can be found in logs.

Reference and Special Thanks

Thanks to Pike R. Alpha for his amazing script.

    I use this script to create a custom CpuPm SSDT, but after apply this SSDT, I suffer GPU Reset issue(I not sure whether this SSDT cause,but I follow this guide “Change DVMT pre-allocated memory back to 32MB and apply the patch.” in another artical. )
    I will remove this SSDT and give a feedback later. My laptop is XPS13-2015.

    It seems to have a problem with CPU ID. Secondly, I can’t find and information to do a correct SMBIOS for MacBook8,1. Secondly, ramge is 800GHz to 1200GHz
    Any assistance would be greatly appreciated.

    Jhawk you need Board-id Mac-BE0E8AC46FE800CC, still weird seeing injection of C2 states as Intel docs mention there are no such states for M-5Y10c

        hi FireWolf i have i35005U and hd5500 , i have tried your ssdt gen and piker gen
