Hello,
I've been running a ML2 for about 2 days, pretty much at stock settings (upped freq to 620) on a macbook pro usb3 port.
It has been running stable for that time, but suddenly the hashrate dropped to 2.1 - 2.5 MH, it used to be stable at 3 - 3.2 MH.
Am I missing something right here? My setup didn't change (no other devices attached).
