Hello,
My miner doesn't run for more than 5 minutes until it gets hung up and blinks the yellow light occasionally (stock settings). I'm running BFGminer 5.4-FutureBit2 for Mac on OSX 10.13.2 Beta. I see it happen whenever there's a difficulty change but not sure if its coincidence. I've tried changing from Mining-Dutch to Prohashing and still having problems with the miner working. I guess I get confused as it works fine initially then gets hung up. I also thought maybe a cooling issue but again, playing with the settings didn't change the problem.
As for a different topic, I'm noticing every time I start BFGminer its pulling up URLs that I've used in the past. How do I clean out BFGminer to stop bringing up previous work. I want a clean slate at each boot up with only 1 URL that is defaults to. I've edited the start-moonlander-2 to read this:
#!/bin/sh
cd -- "$(dirname "$0")"
cd bin
./bfgminer --scrypt -o stratum+tcp://mining-dutch.nl:3322 -u JustAnotherPLT.2 -p d=128 -S MLD:all --set MLD:clock=600
Its still loading with multiple URLs.
Sounds like your Mac's USB port is cutting power. Ive seen this on my Mac as well if the stick tries to pull more than 1-1.5 amps. Try lowering core voltage, stock voltage is too high if your only running 600 mhz.
