After I updated my system from El Capitan to High Sierra, I wanted to use xmr-stak but my version that I compiled under El Capitan doesn't worked anymore. So I decided to compile it new.

My System was updated and Xcode 9.2 with newest Nvidia Driver was installed.

After downloading xmr-stak v2.2 and starting compiling it, I got errors regarding the CUDA Drivers.

Here is my Howto to get it working.

1. Install Homebrew

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Downgrade Xcode to 8.2

- Download Xcode.app from here (https://download.developer.apple.com/Developer_Tools/Xcode_8.2/Xcode_8.2.xip)

- Rename the new 9.2 version to something like Xcode_9.2.app

- Install (unpack) to the Library

3. Downgrade Commandline Tools

- Download CLT for Xcode 8.2 from here (https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_macOS_10.12_for_Xcode_8.2/Command_Line_Tools_macOS_10.12_for_Xcode_8.2.dmg)

- Install CLT Package

4. Downgrade CUDA Toolkit to version 8.0.61

- Download cuda_8.0.61_mac.dmg from https://developer.nvidia.com/cuda-80-ga2-download-archive

- Install CUDA Toolkit

5. Reboot

6. Verify that clang version is 8.0.0:

$ clang --version

Apple LLVM version 8.0.0 (clang-800.0.42.1)

7. Download xmr-stak

- Download from https://github.com/fireice-uk/xmr-stak/archive/v2.2.0.zip

- make a Directory eg. /Users/username>/Desktop/dev/xmr-stak

- extract the zip file to that directory

- cd to that directory

8. Compile and Install

$ brew install hwloc libmicrohttpd gcc openssl cmake

$ cmake . -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOpenCL_ENABLE=OFF -DXMR-STAK_CURRENCY=monero

$ make install

Note: With "-DCUDA_COMPILER=clang" I get an error (clang: error: Unsupported CUDA gpu architecture: sm_60...) so I don't use it!

9. After successfully compiling change the CUDA Driver in the Preferences to the lastest version

10. Run xmr-stak

$ ./xmr-stak

12. Now you can configure config.txt, cpu.txt and Nvidia.txt to get more H/s.

eg. nvidia.txt

"gpu_threads_conf" :

[

// gpu: GeForce GTX 960 architecture: 52

// memory: 1672/2048 MiB

// smx: 8

{ "index" : 0,

"threads" : 13, "blocks" : 24,

"bfactor" : 8, "bsleep" : 25,

"affine_to_cpu" : false, "sync_mode" : 3,

},

],

I hope I have nothing forgotten.

Have Fun :)
