I released a Mac OS X version, thanks to Julien Marcel for his advices on Mac compilation.

It was compiled on a Mac Mini with OS X 10.5.8, using clang 4.2.1,
but I need someone to confirm it works on another Mac computer.

Mac Cheeseburger heh heh.
I'm guessing you have a great fondness for cheese ?

[Patrice Duhamel]

No I don't really have a fondness for cheese, I choose this name because in France we are more known for our cheeses than our chess players.

Thanks Patrice for the Mac support!

Your engines run well on my Mac with OSX 10.9. The pop version is about 5% faster here. Maybe with macports gcc 4.7 or 4.8 you could speed up both compiles a bit.

Thanks for testing.

I tried to install a more recent version of gcc using macports, but it was not able to install it, I don't remember the error message.

I released a new version, Cheese 1.6.1 :

Changes :

- Fixed problem in pondering on Linux / Mac OS X, now use unbuffered stdin
- Fixed problems when pondering was canceled
- Fixed "level" command for Xboard, now use floats for increment
- Fixed : uci command "info depth" was sent in Xboard mode


This version only fix few problems with pondering on Linux / Mac OS X, and with Xboard protocol.
It doesn't change the strength of the engine.
