Question about how do people train their networks. • /r/MachineLearning

I am not relatively new to machine learning, I work with relatively small datasets by using R and Python and it worked pretty well for me, but I am trying to move to a higher level with relatively more complex networks and datasets on my MacBook and I've never be able to wait for the results. I am not a hardware guy so this apparently is a pain in my butt and I need so advices. My laptop uses Intel Iris GPU so when I used tensorflow I could not use CUDA to accelerate my GPU. I searched online and unfortunately I didn't find any helpful information to help to to solve this problem. How do you train your networks?
