I don't yet have an SD adapter. Just got an X2. When I plugin to my X2 to my mac, I get a CD image appearing in my HD. I can't add any files to it, and even if I could I don't know where to put them. There is no Mount option. The other option don't do anything either. I am trying to add my Gameboid BIOS file to the SD card so I can use it. What can I do? Thanks.
