I'm just running off my 2014 Macbook pro... not trying to pull in that kind passive income yet. This is my first look into mining. Only running a couple cores at a time and doing the math myself as to if I scaled it up, how much of a profit I could make.

And free electricity at work, so not concerned about that. Obviously do not want to turn my MacBook into a mining machine, either - it's my daily driver.

I actually ditched this approach and grabbed MinerGate, which I'm trying out today. Anyone have thoughts on it?

I'm having similar trouble.

I followed: http://cryptocurrencyfacts.com/beginners-guide-to-mining-litecoin-mac/

Only thing I did different was use a different wallet - I used electrum.

Anyone have any idea how to fix?
