Disable Bluetooth "roaming" on Macbook Pro

So, my Macbook Pro (15-inch, 2018) are often bluetooth "roaming" and connecting to devices (like my headphones) despite being on battery power with closed lid. I would very much like to disable this feature – seems like a bit of a security/privacy concern as well.

Any ideas on how to disable bluetooth when lid is closed?

Solution 1:

Actually, your MBP do not disconnect bluetooth when closing the lid. So if you turn on devices known (like your headphones) they will connect together. I also found this annoying when I wanted to connect my headphones to my phone but they always connected to my MBP...

You could install blueutil and SleepWatcher via homebrew and set a .sleep code to do "/usr/local/bin/blueutil -p 0" when going to sleep mode.

To use SleepWatcher, make a shell script in your home directory named .sleep and give it permission with the chmod command.

You also can do a .wake code to turn bluetooth back on with blueutil -p 1
