Thanks for the Mac compile.

ChessX GUI says its not a valid UCI engine. MacOS is up-to-date also made sure that permissions are okay.

As a matter of interest I compiled the latest Stockfish development version - runs okay.

Any ideas ?

Does it run under a terminal window?

Looks like a library issue - using the same download link, redownload the file. I used static library option (static-libstdc++) on this second pass which is officially not Apple's recommendation. If that doesn't work, my suggestion would be to install gcc 4.8 using macports since that is is the version of gcc I used to create the exe ( you may want to do this anyway).

Okay great stuff Michael B - much appreciated. I have a few games to look at then will follow your recommendations.

Did as you suggested - no go. Anyway not a problem as Stockfish is good enough for me. Thanks for all your help.
