Choose “Kill Turbo Boost” for less heat and fan noise; choose “Restore Turbo Boost” when you need performance again. Disabling it may slow down demanding tasks. Check the displayed status after switching.

// FAQ
Does TurboKiller support Apple silicon?

No. TurboKiller is for compatible Intel Macs running macOS 13 or later.

Do I need to disable System Integrity Protection?

No. Keep SIP enabled. If the App does not work on your Mac, please send a report instead of changing security settings.

Can I restore Turbo Boost?

Yes. Choose “Restore Turbo Boost” from the menu bar. If an operation reports an error, check the displayed status before retrying.

Why does macOS show a warning?

The App and background component are Developer ID signed, but the legacy system extension means this version is not Apple-notarized. Download only from the official repository and follow the installation steps.
