I am looking for a USB 3.0 to attach to a rMBP. I saw this one on Amazon. http://www.amazon.com/Uspeed-Supers...F8&qid=1351532933&sr=8-7&keywords=USB+3.0+hub But in the system requirements, it says this: "System requirements: Windows XP/Vista/7, Mac OS (Not compatible with Retina Macbook Pro)" Huh? Why would it not be compatible with the rMBP? Related, what is a good USB 3.0 hub that *is* compatible with the rMBP?
