How to mine ETH with GPU on your Mac (revised)

in mining •  7 years ago 

So I updated to 10.13.2 today and it lowered my performance quite a bit. I recompiled but that did not help. Went down to 7.2MH/s on the RP570 and 14.8MH/s on the RX580. Any ideas how to solve this?

    Try below on terminal before starting mining.

    export GPU_FORCE_64BIT_PTR=0
    export GPU_MAX_HEAP_SIZE=100
    export GPU_USE_SYNC_OBJECTS=1
    export GPU_SINGLE_ALLOC_PERCENT=100

    And it may be helpful adding '--cl-local-work 256' option to the end of your ethminer options.

      That helped a tiny bit. Up to 7.8MH/s on the RP560 and 15.2MH/s on the RX580... This is just weird. The only thing that changed was the software update.

        I'm sorry to say that maybe Apple has to optimize device drivers more for 10.13.2
