I just recently upgraded from Bitcoin client 0.3.? to 0.6.1-beta for Mac.
In the old version I had the option of generating coins; I don't see that option here. Activity Monitor shows Bitcoin-Qt consistently using >95% CPU. As I understand it, CPU mining is essentially useless, so I'd like to turn it off, but still have the option to receive coins if I'm paid by someone.
Is this possible?
