What does the Auto-Toggle Bluetooth script do on a MacBook?

The script automatically turns Bluetooth off when you close your MacBook lid and re-enables Bluetooth when you open the lid, preventing unwanted Bluetooth device connections while the MacBook is closed or sleeping.

Why would I want to auto-toggle Bluetooth on MacBook lid open/close?

When your MacBook is closed and sleeping, Bluetooth devices like headsets can still connect to it unexpectedly. Auto-toggling Bluetooth on lid close prevents this behaviour by automatically disabling Bluetooth when the lid is shut.

Do I need Homebrew installed to use the Auto-Toggle Bluetooth script on my MacBook?

Yes, Homebrew (brew) is required. If you do not already have it installed on your Mac, you will need to install it before running the Auto-Toggle Bluetooth script.

Does the script re-enable Bluetooth automatically when I open my MacBook?

Yes, the script works both ways. It automatically turns Bluetooth off when you close the MacBook lid and automatically turns it back on when you open the lid.

Is the Auto-Toggle Bluetooth script complicated to set up on a MacBook?

No, the setup is straightforward. You install Homebrew if needed and then run the provided script, after which the automatic Bluetooth toggling on lid open and close works without any further configuration.

Auto-Toggle Bluetooth on MacBook Lid Open/Close

👁81views

Automating Bluetooth toggling on a MacBook when the lid opens or closes requires a small shell script combined with a launchd sleep/wake hook or a tool like SleepWatcher installed via Homebrew. The script runs a blueutil command to disable Bluetooth on sleep and re-enable it on wake, preventing unwanted headset connections while the lid is closed.

If you’re like me, little things bother you. When I turn on my bluetooth headset and it connects to my Macbook when its closed/sleeping, I get very frustrated. So I wrote a simple script to fix this behaviour. After running the script below, when you close the lid on your Macbook it will automatically turn bluetooth off. When you open you Macbook it will automatically re-enable bluetooth. Simple 🤓

If you need to install brew/homebrew on your mac then run this:

## Install homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
## IMPORTANT: Once the install finishes run the two commands displayed in the terminal window
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> $HOME/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

Script to automatically enable/disable bluetooth:

## Install the bluetooth util and sleepwatcher
brew install sleepwatcher blueutil
## This creates a file which switches bluetooth off when the macbook lid is closed
echo "$(which blueutil) -p 0" > ~/.sleep
## This creates a file which switches on bluetooth when the lid is open
echo "$(which blueutil) -p 1" > ~/.wakeup
## This makes both the files runable
chmod 755 ~/.sleep ~/.wakeup
## Finally restart the sleepwatcher service (to pickup the new files)
brew services restart sleepwatcher
