You don't have to worry about lost cables with the Apple USB SuperDrive. It connects to your MacBook Pro with Retina display, MacBook Air, iMac (late 2012 and later), Mac mini (late 2009 and later), or Mac Pro (late 2013) with a single USB cable that's built into the SuperDrive. There's no separate power adapter, and it works whether your Mac is plugged in or running on battery power.
