Hi, Did anyone ever figure out how to make the Antminer U3 work at 63GH with MacMiner? I'm only able to get 35gh out of it and I've tried everything!
The programmers of cgminer and bfgminer had a lot of trouble with the U3, seems to be a very unreliable device. I'd try both bfgminer and cgminer backends and see which gives you the best results.
MacMiner has been updated with bfgminer 5.3
