helloniklas commented on issue #9217: Installing GPU support on Mac URL: https://github.com/apache/incubator-mxnet/issues/9217#issuecomment-354982838 @cosmo 1. Download Xcode8.3.3 from Apple. This is the version NVIDIA state for Cuda 9.1 Mac. Unzip and rename to Xcode8.3.3.app. 2. Run ```sudo xcode-select -s /Applications/Xcode8.3.3.app``` or to wherever you have placed Xcode. 3. Run ```xcode-select --install``` to install all command line tools compilers etc. 4. Run ```git clone --recursive https://github.com/apache/incubator-mxnet.git mxnet``` to get the latest version currently 1.0.1 which worked for me. 5. ```cd mxnet``` 6. Edit the make/osx.mk file to set ``` USE_CUDA = 1 USE_CUDA_PATH = /usr/local/cuda USE_CUDNN = 1 USE_OPENCV = 0 ``` 7. Copy the mxnet/make/osx.mk to mxnet/config.mk 8. Run ```make``` If you previously attempted to compile you might want to do make clean_all first. You can also run make -j to compile with multithreading. There'll be plenty of warnings but should be no errors. 9. Once finished you should have a file called libmxnet.so in mxnet/lib/ 10. Do ```cd python``` 11. Run ```sudo python setup.py install``` 12. Do ```cd ..``` then you should be able to run ```python example/image-classification/train_mnist.py --network lenet --gpus 0``` to test GPU training.
