So I try to follow some forums to learn it, including how to mining (altcoin) by using my computer.
it's ok if only for learning. you can try mining the ETN coin. follow this step:
1. joined the Pool (you can search with key "Pool of ETN" or anything).
2. Download a software such this: Claymore CryptoNote CPU Miner v3.9 - POOL
3. and a bit must change CONFIGURATION FILE. for the detail, jump to this thread:
https://bitcointalk.org/index.php?topic=647251.0But if find for the profit, I suggest you don't do mining using Mac. that's a device not design for a mining and must run 24/7, it makes a Processor worked 100%. and most very important if using Mac, you would have a bit the hashrate.
