macOS 10.13.1: No AMD OpenCL platform found. Possible driver issues or wrong vendor driver.

[mxjoe]

I own a MacBook Pro with an AMD Radeon Pro 460 with 4 GB. The source code compiles fine but when running xmrig-amd it quits with following message.

compiling code and initializing GPUs. This will take a while... No AMD OpenCL platform found. Possible driver issues or wrong vendor driver. Failed to start threads

Is this misconfiguration of my config.json file, I boroughed it from the Windows version, or is it something code related?

config.json (I reverted user and password back to default):
{ "algo": "cryptonight", "background": false, "colors": true, "donate-level": 5, "log-file": null, "print-time": 60, "retries": 5, "retry-pause": 5, "syslog": false, "opencl-platform": 0, "threads": null, "pools": [ { "url": "xmr-eu.secumine.net:7777", "user": "x", "pass": "x", "keepalive": true, "nicehash": true } ] }

I added command line option --print-platforms, please rebuild with recent changes and show output of ./xmrig-amd --print-platforms.

Also please show clinfo output, better attach it as file or use https://pastebin.com/ there a lot of lines.

I think AMD platform on macOS not named Advanced Micro Devices, Inc. and autoconf failed.
Thank you.

Looks like on macOS always only one OpenCL platform named Apple and it broke autoconfig and it need be rewritten, clinfo output will helps a lot.

try config:

{
  "algo": "cryptonight",
  "background": false,
  "colors": true,
  "donate-level": 5,
  "log-file": null,
  "print-time": 60,
  "retries": 5,
  "retry-pause": 5,
  "syslog": false,
  "opencl-platform": 0,
  "threads": [
    {
      "index": 0,
      "intensity": 100,
      "worksize": 8,
      "affine_to_cpu": false
    }
  ],
  "pools": [
    {
      "url": "xmr-eu.secumine.net:7777",
      "user": "x",
      "pass": "x",
      "keepalive": true,
      "nicehash": true
    }
  ]
}

If index 0 not your AMD GPU, change it to 1, etc.
change intensity to 896, tune it to get maximum hashrate.

Output of xmrig-amd --print-platforms is:

#0: Apple

If I use your updated config.json from above it works! 😊
index 0 is integrated Intel GPU and index 1 is AMD GPU.

I wasn't able to create an output of clinfo as I couldn't find it on my system.
