Why would an external drive specs list USB 3.0 for PC but USB 2.0 for Apple?

    I was looking at this Western Digital drive:

    Western Digital® My Book® Essential™ USB 3.0 External Hard Drive, 3TB

    But in the specs it says:

    Huh? Why would the OS limit the drive speed?

    Here's the product link:

    I can only find that specification on the office depot website - maybe the product was added before Macs had USB 3.0 and they added it so users didn't get confused when their Macs weren't getting USB 3.0 speeds?
