GLboolean boole;
   glGetBooleanv(GL_COLOR_FLOAT_APPLE, &boole);
   printf("GL_COLOR_FLOAT_APPLE: %d\n", boole);


Isn't this an extension?

printf("APPLE_float_pixels: %s\n",
       (gluCheckExtension((const GLubyte*)"GL_APPLE_float_pixels",
                          glGetString(GL_EXTENSIONS))
	   ? "available"
       : "unavailable"));

That will let you know if the card is capable of supporting floating point drawables. Then you need to use the appropriate pixel format attributes (perhaps kCGLPFAColorFloat, and a kCGLPFAColorSize of 64 or 128) when you create your PBuffer. Then your check, executed on the PBuffer's context, should return true...
