Most all Mac's are built to be compact and I would be take caution to run the GPU at 100% mining as the unit would likely over heat. That being said you can turn the intensity down, and if you want to take the risk try Asteroid (http://www.asteroidapp.com/) but please do read about all the warnings.

I think the issue is, that until the bigger exchanges start trading Mooncoin it will remain low in value.

How will you make payment?

I did finally get my Jalapeño from BFL, only about 6 months after they said I would get it. Then it ran at 5GH/s instead of the upgraded 7GH/s I paid for. They never responded to my messages, or even acknowledged I tried to contact them.

Same here, just pre-ordered a Alpha Viper 5Mh/s Scrypt ASIC and would like to post in the order list forum.
