This Apple Desktop Bus Mouse has been fully tested and works perfectly. I tested it on a Macintosh SE, and it has no trouble at all. The cable and mouse have been cleaned, and the only physical thing about the mouse is it has yellowed a little bit over time. Other than that, everything is in great shape cosmetically and functionally. The ball is very clean and rolls perfectly. Please feel free to send me any questions or offers!
