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
Thanks for this Andrew.
$ which blueutil
blueutil not found
Did you run “brew install blueutil”?

blueutil: A full installation of Xcode.app is required to compile
this software. Installing just the Command Line Tools is not sufficient

This script seems to work only if you have the full version of Xcode installed (Apple general IDE).
