How to mine ETH with GPU on your Mac

in mining •  7 years ago 

Hello! This is the first tutorial I found that works for gpu mining on my Mac. Thanks you! I do want to use my GTX 970 eGPU (device 0)instead of my MBP's graphic card (device 1). The devices are recognized by eth.

Do you know that there's a way to do it? I tried adding -U but that didn't work. I ran -X but appears to be only running my MBP's card. I was given this message: CUDA support disabled when adding -U. Configure project build with -DETHASHCUDA=ON. I don't know how to use it though. If I add --opencl-device 0 to the string connects and I get speeds of Speed 0.00 Mh/s gpu/0 0.00 [A0+0:R0+0:F0] Time: 00:00. Any ideas? TIA, Mark

    Have you tried compiling with -DETHASHCL=OFF -DETHASHCUDA=ON ?

          My eGPU is running under Sierra. I use it for 3d rendering without a problem. I have mined bitcoin with it via Asteroid (a total waste of time and electricity). I am hoping to play around and mine a bit of Ethereum. Any suggestions? Thanks again.

            From your log it looks like ur eGPU is device 1 and ur integrted graphics is device 0. Have you tried --opencl-device 1 instead of --opencl-device 0 ?
