It's just the Mac OS trying to figure out what keyboard is attached to your computer.
It asks you to press the key directly to the right of the left 'Shift' key (as indicated above) and then the key directly to the left of the right 'Shift' key so it can determine what keyboard (and it's layout) you have. You should only have to do this once, or whenever you change keyboards, or leave one unplugged.
