USB short protection I was prototyping some USB things and I was wondering if the Mac USB ports have any short-circut protection.



If I were to connect Vcc and GND directly together would it break my Mac? Would the motherboard be borked?





Specifically, I'm using a Mid-2012 Retina 15" MacBook Pro and am looking to know if it has any protection or resilience against damage of this sort?
OS X should identify the port as having high current draw and shut it down until you unplug the device. 

Source: I was doing exactly this and ended up accidentally shorting the Vcc and ground pins, and got a notification center message saying this.
