How to install CUDA 10.0 on OSX 10.13.6

If like me you had some problem using CUDA on your High Sierra computer (samples not compiling or having driver error at execution), here's my recipe to make it work.

References used :

Clean up

If a previous version was installed, uninstall it using the official scripts :

sudo perl /usr/local/bin/uninstall_cuda_drv.pl
sudo perl /Developer/NVIDIA/CUDA-10.0/bin/uninstall_cuda_10.0.pl

Graphic driver

Download the last version of the NVidia driver for OSX 10.13.6 (which was actually this one for me).

Your graphic card might not be listed as a supported product, but it still works.

Install it and restart

Go to System Preferences > NVIDIA Driver Manager > Updates > Check Now and update if needed

A NVidia menu now appear in your menubar to switch between the NVidia driver and the system default one
CUDA driver

Download the lastest version of CUDA driver for OSX here (which was actually this one for me)

Install it and restart
CUDA Toolkit

Download CUDA Toolkit 10.0

When installing, only select Toolkit and, optionally Samples (recommended to test your installation)

Go to System Preferences > Energy Saver and uncheck Automatic graphics switching
Update Environment variable
```
sudo nano /etc/paths
```
Add the line /Developer/NVIDIA/CUDA-10.0/bin
```
sudo nano /etc/bashrc
```
Add the line export DYLD_LIBRARY_PATH=/Developer/NVIDIA/CUDA-10.0/lib\ ${DYLD_LIBRARY_PATH:+:${DYLD_LIBRARY_PATH}}
Xcode downgrade

To be able to compile, download Xcode 9.4 here (an Apple account is necessary).

Extract and rename the file as Xcode_9.4.app and put it in the /Application folder

To change the current Xcode :
```
sudo xcode-select -s /Applications/Xcode_9.4.app
# if needed
xcode-select --install
# to go back to default
sudo xcode-select -s /Applications/Xcode.app
```

There you are, you should now be able to compile and launch CUDA apps on your system !
