I have now prepared a GUI release of Stockfish 1.7.1 for Mac OS X. Before uploading it to the Stockfish web site, I would like to have some independent confirmation that it works. Please download from this URL:

Before you get too excited, this is still only the old and amateurish Glaurung GUI, with a few minor changes. I have to start working on a new and more polished GUI some day.

The binary probably requires Mac OS 10.6, but might also work in 10.5. It certainly won't work in 10.4. It currently doesn't support PowerPC CPUs (I'll add that later if anyone is still interested), but should work on both 32-bit and 64-bit Intel CPUs. I'd appreciate if those among you who own an Intel Mac running 10.5 or newer could download the GUI and check if it works for you.

There is also one very minor difference in the engine code compared to the stand-alone 1.7.1 engine: If the engine detects 8 CPUs, it will assume that it is running on a quad with hyperthreading, and will use 4 threads by default. This is because quad-core iMacs are probably far, far more common than the outrageously expensive 8-core Mac Pros.
