title: can we run digits or caffe on Mac without GPU?
body: <p>I have seen caffe installation for Mac. But I have a question. If my Mac does not have GPU, then I have no chances to use GPU?? and I have to use CPU-only?
  or I have the chance of using (virtual!) GPU by NVIDIA web driver?</p>
  
  <p>Moreover, can I have digits on my Mac? as I try to download it, it does not have any options for Mac download and it is just for Ubuntu!</p>
  
  <p>I am very confused about these questions! Can you please make me clear about these?</p>
