True, could be, I use boost::barrier and they are implemented over boost::mutex and we know all the problems boost::mutex have under MacOS ... I can not believe this problem has not yet been fixed, grrr.
I guess we will have to replace boost::barrier with something implemented over Luxrender's lux::fast_mutex for the Mac.
@Eros: your results are quite good, if you download the 2.0 version, you should be able even to double them by using both your GPUs.
