To see the differences between having Turbo Boost enabled or not, you can do the following tasks: How to know if Turbo Boost is enabled (or not): If you don’t want to always be opening your terminal, compile the code, make sure you don’t forget to re-enable it, etc. This is a very simple extension that manipulates the MSR record writing the Turbo Boost flag. I’ve started to look for applications, and the only thing I found was this cool kernel extension created by “nanoant”. and your fans go to max speeds while your CPU keeps crazy ranges like 93 – 98 ✬. If you are like me, you probably do some high cpu demanding tasks from time to time, like photoshop editing, video transcoding, casual gaming, etc. This will reduce your parallel processing performance so, in some situations, you better disable it. Parallel Processing: Turbo Boost is enabled when one of the CPU cores reaches 100%, increasing the core Mhz, but It won’t do it if all or your cores are 100%, since that will create a lot of overheat. With Turbo Boost disabled I’ve been able to get up to 20 ✬ degrees less!!!, that’s a value worth considering. This is controlled by hardware, but if you want your computer to live long, better keep it as low as possible. Turbo Boost is enabled by default on all Macs that support it, but why anyone should want to disable it?ĬPU Overheat: When Turbo Boost is activated, prepare to experiment high temperatures on your CPU, since it pushes till it reaches almost the Junction Tº, usually 100 ✬. Just run the app as root doing something like 'sudo /Applications/Turbo\ Boost\ Switcher.app/Contents/MacOS/Turbo\ Boost\ Switcher'.It also offer another features so you can get cool things in exchange for supporting the app :). Buy the PRO version that installs a daemon and doesn't need to as for root since it uses IPC to communicate with the main app.To avoid this behaviour, you can follow two approaches: That's because kernel extensions must be installed as root and the user privileges are stored on a system cache. You can read more about this here.ĭepending on your user configuration, OSX may ask for root password when enabling / disabling Turbo Boost. Just go to System Preferences -> Security and Privacy and click "allow" after trying to disable Turbo Boost for first time. Try again, it should work.Īlso, and just if you're running on macOS High Sierra for the first time, you'll need to allow the kernel extension to be used the first time you try to disable Turbo Boost. Go to your System Preferences->Security and Privacy and mark the option “Anyhwere”. If you see a message saying the app “can’t be opened because it is from an identified developer”, then you need to change your settings to allow not-signed apps to be installed. If using macOS Sierra, before running move the decompressed app to other folder or it won't run. Once downloaded/compiled, just unzip and double click on your “Turbo Boost Switcher.app”. You can download the binary application or the source code to compile it with XCode. Other languages in beta (Russina, Chinese, German, French, Polish).
