Query: Not for Mac

This item comes with U3 stuff imbedded, which is useless to Mac users. It is not possible to throw away the U3, which shows up as a separate disk icon on the desktop. You also cannot reformat this "disk." It takes up 200 MG that one loses as storage space, and puts two icons on the desktop. This disk is simply not satisfactory for a Mac user unless you want to put up with lost space and useless icons on the desktop.
