So I noticed something very interesting yesterday. When my Alienware was running Windows, I could not charge my iPad on my computer. But, as soon as I installed OS X on my alienware PC, my iPad now charges as long as it's plugged into a system running OS X. So there are cases when my iphone is fully charged but I still need to plug it into my Mac, is there a terminal command possibly that could disable all devices from charging? Charging an iPhone while it's at 100% battery for a few hours is not good, I'm wondering if there's a way I can plug it in without charging.
