The below article is in need of updating due to updates to the VTC mining algorithm, in the meantime you can download a Mac version of sgminer I've compiled here http://macminer.fabulouspanda.com/commandline/sgminer/ which includes instructions. This article and MacMiner will be updated shortly to reflect the changes but the process remains much the same as that below
You can both CPU and GPU mine Vertcoin
EDIT: MacMiner now includes the VertCoin CPU and GPU miners - read on if you'd rather use the command line than an app for mining
Download the CPU miner or compile it yourself:
Is the compiled Github CPU miner project for Vertcoin: https://github.com/Bufius/cpuminer-vert
If you unzip it and put it in your Applications folder, you would run it like this:
Open Terminal in the Utilities folder
press enter then type
./minerd -o http://18.104.22.168:9171 -u username -p password
Replacing pool and user information with your own. Press enter and cpu mining will commence.
For GPU mining, there is a special version of cgminer that supports VertCoin. For that, instructions are included in the download. Make sure you use --scrypt-vert! http://downloads.fabulouspanda.co.uk/vertminer-cg-mac.zip
This was compiled from the code on this github project: https://github.com/Bufius/vertminer-gpu
I like P2Pool, and you can find a list of vert coin P2Pool nodes here if you need a pool: http://p2pool.vertcoin.org
With P2Pool, there’s no registration - just use your VertCoin Address for your username and password.
