New MacBookPro does not recognize new Superdrive or CD.
Today, I received my new 13" MBP with Retina Display and a new USB SuperDrive. I downloaded and installed El Capitan. I have connected the SuperDrive (SD) but the computer does not recognize it. I have tried 2 different software program CD's. I can hear the noise of activity when the CD's are in the SD but no image on the desktop. Eventually the CD gets ejected. Is the SD defective? (or am I?)
Mac Pro, OS X Yosemite (10.10.1)
