Optimized Stockfish 1.4 for Mac?

[schlucke]

Is an (Intel compiler) optimized 64-Bit Version of Stockfish 1.4 for MacOS anywhere out there? In the past days Tord provided such optimized executables for Glaurung, but I can't find optimized Stockfish stuff out there ....

That's because I'm too busy and lazy to update my web page. You'll find an optimized 64-bit Intel binary here (requires Mac OS X 10.5 or newer):

Thanks, not everybody has an Intel compiler installed

It makes a little difference, seems that GCC gets closer to ICC!?
