"MM2k is good."
"Sure, it's good; that's what I'm currently using. But it also has problems, especially on the Mac."
Maybe it's your computer. Have you made sure the wind-up key is completely cranked? Did you disable the child-proof lock (or ask the help of an adult in doing so)? Did you remember to upgrade from the standard Sesame Street keyboard layout to the Sponge Bob layout? Have you checked the batteries (2 X AAA)? Did you clean out the lint trap?
Failing all that, have you considered fixing the problem by selling your Mac and, with the proceeds, buying two PCs, paying for a new roof, a new transmission for the car, two new roosters, five goats and a couple of wives from Russia?
