MacBook Pro
NVIDIA GeForce 8600M GT OpenGL Engine	
Vendor Name                   	NVIDIA Corporation
Version                       	2.0 NVIDIA-1.5.36
GL Shading Language Version   	1.20
this is the information from the OpenGL Driver Monitors
with the OpenGL Extensions GL_EXT_geometry_shader4

its openGL Version 2.1
for linux and microsoft you can get drivers for GLVersion 3.1 from  
nvidia

mac wait for apple update

no i got the error "cannot load shader now" from this part when it has  
VERSION_2_1
   if(!GLEW_VERSION_2_0 && !GLEW_ARB_geometry_shader4) {
     post("cannot load shader now!");
     return;
   }
VERSION_2_0 work

so i dont understand why V_2_1 failed - openGL 2.1 and latest GLEW  
version 1.5.1 are installed

at least the geometry_shader are functioning :)
