I ended up solving the issue. For those that are curious and future Mac users I will briefly document what I was doing wrong:

It seems that for whatever reason my Mac was not recognizing the Antminer S1 when they were directly connected by ethernet. After connecting the Antminer directly to the router instead, I was able to log in to my router and discover the Antminer's IP address and then log in from there.

Hey all,

I recently purchased an Antminer S1 and I'm having some trouble setting it up. When I type the IP address into my browser I get a "webpage is not available" message. I'm on a mac and it seems that most of the tutorials for these miners are geared towards Windows or Linux. I was wondering if anyone had any advice?
