bfgminer starts and dies and starts again in an endless cycle of samsara

Hello, I was hoping I could get some guidance on how to get bfgminer working on my machine. Here are my specs:
OS X 10.10.5
AMD FirePro D500 3072 MB GPU
3 GHz 8-Core Intel Xeon E5 CPU

I think I have CPU Miner working, I'm getting hash rates for each thread in the output terminal. Though it always displays "0 KH" and "Stating..." in the GUI

  • What's the output of bfgminer when you try to mine? Are you using GPU or ASIC?
  • I'm using GPU. The output I get at first is "bfgminer has started. The primary pool is set to stratum+tcp://stratum.slushpool.com:3333 and the user is set to" my worker id. The output says: "[2017-05-08 13:26:26] Started bfgminer 5.4.2-unknown

    Then I get "Settings changed. Your miner was restarted automatically after a sudden stop at 13:27:33."

    Does this help?
  • Hmm, doesn't look as though it's really getting started. Try setting the Intensity very low to see whether that'll let it get started and look around to see what worksize/intensity settings other people are using with the FirePro D500.
  • I ran with a lower intensity and enabled debugging output and here are some errors I got back after tossing out what looked okay:

  • Error -54 is often associated with too high an intensity, you could try minus values… The trashcan Mac Pro probably isn't a great machine to mine with, having a 'thermally constrained' design.
  • Hi,

    How would I be able to tell if it is actually using the usb miner I have plugged in or just the one in my computer?

    Also I see Mh is moving but in the accepted field it stays 0 can someone explain any of this.

    very new to this.

    Thanks
  • Check the log in the miner window and the API Output window for more detailed output. Sometimes 0 accepts means you're not mining fast enough to solves shares which sound like the case if you're mining Bitcoin in Mh rather than Gh/Th
  • I am having the same problem. Here is my crash log:
