I've built ocminer's cpu miner (https://github.com/ocminer/cpuminer-hmq1725) using both homebrew and macports after making a few code changes, but there is no downloadable binary for a mac miner that includes the hmq1725 algo.

If you know enough to give building it a try it can be worthwhile.  If you do try and have any questions, you can PM me and I will do my best to help with any trouble that you run into.

The optimized cpuminer by joblo uses instruction sets that are formatted differently from how clang wants to run them, so it is much more difficult to make work on mac, and I have yet to get it compiled. 

For sgminer, I haven't tried to compile that yet.  I might try and tackle it at a later date, but because I have no video cards in my mac, I cannot reliably test it.
