UCI chess engines for Macintosh?

I've pounded on Google for half an hour and I can only find one UCI chess engine for Mac - Stockfish. I have Stockfish running in Chess Openings Wizard (Macintosh version) but I'd like to test some others.

Surely I must be missing some. Know of any other OS X chess engines?

Where did you find the Mac version for the Openings  Wizard?  I looked it up but didn't find it...

Most chess programs are for Windows...

I have Komodo running on my iMac. I use Hiarcs Explorer UI containing Komodo, and altho not Chessbase Hiarcs offers basic database functionality

The Mac version of Chess Openings Wizard is being beta tested.

People often quote this thread, saying that the Mac version of Chess Openings Wizard is still being tested. The Mac version has been out for a couple years. It uses UCI chess engines for Mac.
