My Droid X2 O'Reilly manual says that by plugging my Droid into a Mac computer USB port I will get a USB trident icon on my menu bar. And, that upon clicking on the trident I will get a menu that includes a choice of Mass Storage Mode. Upon selecting MSM I will get a box on my screen allowing file transfers. I get no trident. Does Mass Storage Mode exist? How can I access it? Remember this is for a Mac.
