Hello all, I just got my first Mac, a 15 inch MBP. I bought this Sandisk Memory Card adapter: http://www.amazon.com/Sandisk-SDAD109A11-Digital-Card-Express/dp/B000W3QLLW When I plug it into my MBP nothing happens. Is an icon supposed to pop up on the desktop like when you put a CD in? Is there a way to see if my ExpressCard slot is operational through Mac OSX? Thanks for any help.
