Connect & Disconnect Bluetooth Devices (via `blueutil`) 📶

After buying new bluetooth headphones I got annoyed with manually connecting and disconnecting them with the mouse, so I sat down and created this little script here.

It lists all your paired devices and toggles the connectivity status for the selected device. Enjoy!

⚠️ You should have blueutils installed via brew. Simply run brew install blueutil. The script will recognize whether you have it installed and asks if you want to run the command in the terminal
