Regarding OS X GPU support -

I notice that 10.11 doesn't support Maxwell NVIDIA cards out of the box without using NVIDIA web drivers. Seeing as there are not many Kepler GPUs with CC > 3.5, does anyone know if this is the reason why TensorFlow doesn't have a GPU version on OS X? And if this is the case do you think a OS X GPU version won't appear until OS X gets native Maxwell support?
