Im new to mining. Looked at it back in 2011 and started following this year again. I have an iMac with Macminer GUI installed. I ran the GPU miner for half the day and noticed zero accepted zero rejected and cant figure out whats going on. Any help would be appreciated. Im connecting to minergate pool and have my address and password set. As for which coin Im mining Ive tried a few to see if it was parameters or maybe my hashtags was too low.
