RB-834 Pad not recognized by Mac

I have a MacBook Pro and am running SuperLab 4.0.7b. When I try to run an experiment that uses the pad, I get an error message that says that SuperLab cannot find the pad. Any ideas on how to help SuperLab recognize the pad? The green light in the back glows when the pad is plugged into the USB port.

Thanks, Robert

Hi Robert,

Did you install the USB driver for Mac OS?

On the Mac, the green LED always turns on when you connect the response pad even if the driver is not installed. On Windows, the LED turns on only if the driver is installed and Windows can “see” the response pad.
