I may be doing something wrong but I am unable to use PiMAME.

I have tried a few different ways of putting the image on my SD card with similar results.

I am unable to start it the farthest I've gotten was when it asked me to type in my login but I couldn't type.

More often it stops while loading my USB devices. It gets past the hub and onto the keyboard then just stops progressing.

I am suing a mac to load up the SD card I have tried the terminal command, a wizard, and Disk Utility.

I haven't used the Pi much so I am probably doing something wrong.
