Question

If a USB device is plugged or unplugged, my MacBook Pro wakes up from sleep. Can this behavior be changed somehow? That is to say, I do not want my Mac to wake up when a USB device is unplugged.

Was it helpful?

Solution

The reason why the Mac awakes is because the USB device is drawing power from the Mac’s USB port. When you disconnect it, there’s a change in the voltage and the Mac awakes (same goes when you plug one).

Curiously, there’s a way to do it in Windows.

According to the guys at Super User, this is not possible on a Mac. At least not that we’ve discovered yet.
