Don't be to sure that will work. I have a MacBook Air and the USB Superdrive, but when I plug it into the Mac Pro, or into my MacBook Pro, it is not recognised, and it will not let me insert a DVD.
I don't know when is holding it back, but it works just fine in my MacBook Airs.
Never tried it on the Pro, since it doesn't work, I can go get a cheap one that will, or use target disk mode, or transfer via flash drives from a PC that has a DVD drive, and so on. DVD read/write is slow as Christmas, molasses, etc. anyway. I may use an optical drive once a month.
