We have a small group mining on a variety of laptops (quite a few are MacBook Pros running MacMiner). They're not running full-time, nor are we looking to do much more than earn enough to learn and participate. I'm yet to hear about problems from anyone, but will make sure to ask around and let you know what our experience is.
Given the circumstances, I think the Macs will be fine. Which coin do you mine?
We're exclusively mining BitCoin. It's our opinion that it's the currency with the greatest opportunity to become widely used. If it's good enough for the Winkelvosses (sp?), analysts at Citibank, the Government of China, it's good enough for us!
