You'll find a Mac version of the miner here:

Edit the batch file replacing the PTS wallet address with your wallet address in which you would like to receive your PTS. Run the batch file to start mining. Payouts are done every 24 hours to your wallet.

I heard the Let's Talk Bitcoin interview and was very interested in what is being developed so I came over hoping to be a part of this but I'm starting to think that perhaps this is just out of my league.  Hoping somebody can give advice in the best way forward. 

I'm a typical Mac user.  Actually, I'm a little more savvy than most of my friends when it comes to getting around the computer, but I am not a tech guy or have any real skills at programming or anything like that. 

Anyway, I downloaded and started running Protoshares QT a couple of days ago and after adding some lines in the console as suggested, I see  8 connections but it says I am not mining Protoshares. 

Is there a step by step set of instructions for somebody like me or am I hopelessly too ignorant to participate?

thanks!
