I would personally not wire any amount of current to a USB peripheral connected to my MacBook.

Its like grounding it, same thing you do when you touch it. pretty safe no?

I guess, but it depends on what the other end of the wire is connected to.

I guess a ~10kohm resistor in series couldn't hurt, should something go wrong. After all your finger is not exactly super conductive in the first place...

Switching a wire between mid-air and ground passes 0 current in both states which sounds like a pretty safe amount, though.
