Minergate is nice and simple for my desktop mining - and they work on Mac! - but I had an issue when I focussed my Innosilicon on their Litecoin pool. Ran it for a couple of hours: 7600 good shares, 79 bad shares, and 94 INVALID SHARES! WTF - basically all that time was wasted on their pool and I have a balance of 0.00000000. Not impressed. They claim it is because of old software within the ASIC, but Litecoinpool, Mulitpool, Nicehash, and Prohash haven't had any issue with my Innosilicon. Recommend going somewhere else.
