This question already has an answer here:
I have a MacBook Air running 10.7(Lion) with an Intel Core i5 processor
I want to try to mine bitcoins for fun. I understand that I alone will probably not be able to get any bitcoins from mining so I registered for some mining pools (Slush's pool, BTC Guild) and tried various applications to try to mine (MacMiner, guiminer, and cgminer)
For all of these, I am able to connect to the mining url with my credentials. guiminer shows that I have a speed of about 2 MH/s. However, nothing else seems to happen even after running these programs for about half an hour. I don't seem to be contributing to any of these pools.
Can someone tell me what is going on wrong?
