Hi there. Excuse my absolute noob-ness. I have a Macbook Pro with an Intel 4000 card and have tried to run Asteriod to mine Litecoins and Dogecoins. The max rate I can seem to get is 13 or 14 kh/s. Is this the limit of my card/laptop or is it possible to get a better rate? I am in the US on US pool servers.

Thanks!
