IOIIIO Posted November 23, 2019 Share Posted November 23, 2019 It took some messing around, but I have made a kext patch which can be used as a superior alternative for NullCPUPowerManagement.kext. Since it still allows AICPM to load, we can now load X86PlatformPlugin and by extension AGPM on a system where CPU PM doesn't work. This is useful on for example AMD systems, where CPU PM cannot be enabled properly. So far tested on Catalina and High Sierra, but should also work on other versions, and is reported to give very decent performance improvements when paired with an appropriate SSDT-PLUG SSDT and AGPM injector kext. Does not work in combination with NullCPUPowerManagement.kext From: D0 05 00 00 84 C0 74 46 E8 To: D0 05 00 00 84 C0 EB 46 E8 On: com.apple.driver.AppleIntelCPUPowerManagement 7 1 Link to comment Share on other sites More sharing options...
Riggs Martin Posted November 26, 2019 Share Posted November 26, 2019 It is for OpenCore only? Link to comment Share on other sites More sharing options...
nexusneko Posted November 26, 2019 Share Posted November 26, 2019 It seems to work in Catalina. Good work. Link to comment Share on other sites More sharing options...
