I'm pretty new to the world of Bitcoin; though, a few months back I tried mining. I had everything working, but then I stopped.. Anyway, now I'd like to start up again, though I've wiped my computer and reinstalled OS X since then.  

I had been using a GUI (GPU) Miner, but now I have no idea how to find it.. I think it had something to do with poclbm, but I can't be sure... Anyway, if anyone has had any luck with one, please inform me.  

Thanks. 

Btw: I'm running 10.7.4
