There used to be a option to disable bluetooth devices waking a Mac. It was removed a couple years ago. I can kind of understand because this would also prevent a keyboard/mouse waking the Mac, which isn’t ideal. I assume a lot of people were turning this setting off then complaining their Mac won’t wake.

However, if a Macbook is sleeping and closed with no peripherals attached, I can’t see any use case for waking from bluetooth. It doesn’t make sense.
