I asked this in my 2016 MacBook Pro thread, but no answers. So I'll try here: USB C- Since owning a new 2016 MacBook Pro (see sig), I've ordered two different sets of USB A to USB C cables from Amazon (Link 1, Link 2). Neither one of them will power an external portable HD which has a USB A connector. The Apple USB to USB C adapters work fine, and they fit snug into the side of the MBP, but the item from Link 1, the USB C connector looks identical, but when plugged in it sticks out a little bit. In other words, I can see metal, when it's plugged in, where I can't with the Apple adapters. I have returned both of these cable sets as defective. Is there something I'm not getting about them? Thanks!
