etorix Posted October 3, 2021 Share Posted October 3, 2021 You have at least one unnecessary quirk: Kernel>Quirks>AppleCpuPmCfgLock. AppleXcpmCfgLock does the same thing, if you cannot unlock MSr 0xE2 from your BIOS. I'm not sure if it's the culprit, but it does affect CPU power management… Quote Link to comment https://www.insanelymac.com/forum/topic/349131-intel-core-i7-8700-not-turbo-boosting-macos-116/#findComment-2768274 Share on other sites More sharing options...
frogman1212 Posted October 3, 2021 Share Posted October 3, 2021 Hello. I also use i7-8700. It still has enough power, isn't it? Let's work hard together.

Acid Rain Posted October 5, 2021 Author Share Posted October 5, 2021 (edited) I "fixed" it using this guide https://dortania.github.io/OpenCore-Post-Install/universal/pm.html#enabling-x86platformplugin But the side effect was my cpu got much more hotter Before: CPU Frequency under idle 1.5Ghz-2.6Ghz Temp: 42C, Under Moderate Load 3.2-3.5Ghz 50-60C After: CPU Frequency under idle 3 Ghz Temp: 55C, Under Moderate Load 4.3Ghz Temp: 70C Only try it if you have a good cooling solution.
