Turbo Boost Switcher – autostart under MacOS Big Sur without password prompt

Quickly noted for me, how to set up Turbo Boost Switcher to start automatically under MacOS Big Sur without a password prompt and disable Turbo Boost at startup.

Prerequisite: Turbo Boost Switcher is installed and working manually operated? Yes? Good! –> Close existing running instance of Turbo Boost Switcher NOW.

Create a new file:

sudo nano /Library/LaunchDaemons/com.turbo-boost-switcher.plist 


Paste this text and save:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">
           <string>/Applications/Turbo Boost Boost Switcher</string>



sudo launchctl unload /Library/LaunchDaemons/com.turbo-boost-switcher.plist
sudo launchctl load /Library/LaunchDaemons/com.turbo-boost-switcher.plist


Set the checkbox “Disable TB at Launch” in the GUI:


When you restart your Mac, the Menu Bar should display the Turbo Boost Switcher Icon as disabled (as shown in the screenshot above). This can take a few seconds, so be sure to wait a bit after you restarted 🙂
