The kext does not load in single-user mode. If you installed the kext anyway, and cannot boot your mac anymore, simply boot up with -s option (single-user mode).If your computer panics at this moment, do NOT install the kext. The recommended way is to install PMdisabler.kext (find it via Google) which will disable the Apple kext without having to remove it.īefore you install the kext into your Extensions folder, you should set its permissions and test-load it to make sure it works - sudo chown -R root:wheel ~/Downloads/IntelEnhancedSpeedStep.kextsudo chmod -R 755 ~/Downloads/IntelEnhancedSpeedStep.kextsudo kextload ~/Downloads/IntelEnhancedSpeedStep.kext You must disable or remove AppleIntelCPUPowerManagement.kext before you can use this kext.Use v1.4.0 which is the latest STABLE version. There have been reports of kernel panics. Do NOT use v1.4.5 — that is beta software intended to test a few features.I'd like to point out a couple of important things, to minimize any damage: I'm the author of the kernel extension this post links to. However, you can also edit the TargetCPULoad parameter in /System » Library » Extensions » IntelEnhancedSpeedStep.kext » Contents » ist file. ![]() There you'll find the command sysctl -w kern.cputhrottle_targetload=XY. Also see sysctl -a | grep kern.cputhrottle from Terminal, and read the AutoThrottle wiki for more information. Now we can see dynamic frequency and power changes. ![]() Don`t forget to repair permission (in Disk Utility) when done, then reboot your Mac. Just download IntelEnhancedSpeedStep.kext.1.4.5.zip, then copy IntelEnhancedSpeedStep.kext into /System/Library/Extensions. Here's how to enable SpeedStep on any Mac: Use the xnu speedstep kernel extension. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat dissipation."Īpple implements SpeedStep on certain Macs, but not all of them (and if you've built your own Mac, you may not have any SpeedStep support). As described on Wikipedia, SpeedStep "is a trademark for a series of dynamic frequency scaling technologies (including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed by software.
