Not sure what i'm doing wrong - went to MODE > LOAD, then USB, then mount - nothing shows up on my computer.

I''m running EL Capitan.

Is there a driver I need as well?

any help is much appreciated.

Open Terminal.app and type "diskutil list" after you insert the USB cable and press mount.

In my case, when I tried to use a specific CF card the MPC would present the disk over USB but would also cause diskutil to hang, as if it had presented the disk incorrectly. I don't know enough about USB mass storage to diagnose this but it seems that the MPC wasn't presenting the disk correctly.

When I went back to my 2GB CF card, diskutil would list the disk and immediately successfully complete, not waiting for anything else from the MPC.

My suspicion is this has nothing to do with your Mac and everything to do with either the MPC or the card/disk you are trying to mount, sorry.
