Permanently disable Intel Turbo Boost on macOS, so your MacBook doesn't act as a portable frying pan anymore.
-
Partially disable System Integrity Protection (SIP) to allow unsigned kernel extensions:
a. Reboot Mac into recovery mode by holding down cmd+R when booting
b. While in recovery mode, open Terminal and execute
csrutil enable --without kextc. Reboot back into normal mode
-
Install the kernel extension and the launcher by running and entering admin passwords
./do-chill.sh-
macOS would prompt you to allow the kernel extension in the System Settings, do that.
-
Reboot
-
Check whether the kext is loaded:
kmutil showloaded | grep no.vtek.DisableTurboBoost- Check that the Turbo Boost is disabled:
sudo powermetrics | grep "CPU Average frequency"should give CPU frequency not above 100%.
This small kernel extension will enable bit 38 of the MSR register MSR_IA32_MISC_ENABLE which causes the CPU to disable turbo boost.
Take a look in the manual for more info.
Authors take no responsibility for whatever harm this kernel extension may cause your system.
The kernel extension is written by Vegard Løkken (https://github.com/veloek/DisableTurboBoost.kext), and was based on an outdated repo (https://github.com/nanoant/DisableTurboBoost.kext) by Adam Strzelecki.
The kext binary build, lauch script, and automatic installation was produced by Ivan Markin (https://github.com/unkaktus/chill).
