Hello, this is my first post here (so please be kind

)
I have a MacBook Pro running 10.8.4 and so far I haven't had any luck getting the M92 to show up in Finder. Opening a few files through DropBox was relatively painless, but I will need to access an entire semester's worth of graduate coursework, so I need something faster than wifi.
Am I missing something obvious? I've nosed around here for a while, and the manual is very minimal.
Any suggestions are welcome!
