I installed Bfgminer 3.1.4 and everything was running fine.
I was tinkering around trying to build bitcoin-qt from source and changed a few things, now I get a bus error: 10 when I try to run Bfgminer 3.1.4 @ command prompt (terminal) in Mac OS X 10.8.4
How do I fix it? I tried restarting, reinstalling and NOTHING seems to work... I am stuck using Mac Miner for now...
Seems to be an issue with Bfgminer, ran it once on a separate system (10.7 instead of 10.

and after shutting it down and restarting it, I get the same bus error and NOTHNG seems to fix it...
What gives?
Did you by chance unplug and replug an erupter?
Have a look at your config file. /Users/*yours*/.bfgminer/bfgminer.conf . It is hidden so you may need to use Shift-Command-G from Finder to get there. There are some 'odd' configs in there such as kernel location that came from the repository during the brew pull/compile. Delete/rename the conf file and restart BFGMiner. Once I did that, all was right with the world. I recreated the problem and solution on 10.7 and 10.8. I hope it helps.
