Thanks! This should be added to the download page.

Very very nice.

I added a little fix after I made the binary.. It will try to leave one core unused so that it doesn't bog down.  I have a MacBook with a 9400M as well and since the GPU is so slow (only about 500k/sec) it doesn't really lose that much if there's 2 CPU threads running.  But on my desktop with an 8800 (about 3500k/sec) it drops dramatically if I don't leave one of the cores free.  So really on the MacBook it might be better to just run 2 CPU threads anyway, maybe I'll add an option for tweaking.. this is all just a prototype right now.

I'm getting about 950k/sec total with 9400M + one CPU thread on the MacBook I have.  It seemed like i was getting about 1000-1100k/sec with 2 CPU threads + 9400M.  About 700-800k/sec with just the CPUs.

Installed and seems to be running,

But I don't get any stats, this is what I get:

Hi and thank you for your efforts. Just wanted to inform you that the binary crashes on launch on my macbook. Here's the error report:

The issue seems to be similar to whatever's going on in this post (http://forum.bitcoin.org/index.php?topic=371.0) but I'm a bit of a newbie so I haven't tried compiling anything..

Seeing as the thread was started a year ago, just to verify: Are you the only one currently working on the mac client? Just realized it doesn't seem to use NAT-PNP/UPnP due to the low connection count i got. With Bitcoin constantly in the news a lot of people who aren't comfortable doing manual port mapping (might not even run devices with static internal IPs) are probably trying it out now.

(A secondary but related problem is not mac specific: Not being able to run two Bitcoin clients on the same local network with one external IP without manual pass-through configuration)
