If you're like me and run using a Mac, one of the first things you will notice, is a complete lack of instructions for using almost ANY mining software for alt-coins. As if the alt-coin-community has completely ignored the fact that Mac's GPU power is on record as having been the best of the best, for decades. I've taken my Mac to the edge of space and back in high altitude and micro-gravity flights for accurate data collection. I've used it to calculate all aspects of Military applications, and I've even used it to code Windows and Linux software to enble mass product production using cheaper disposeable equipment for military applications. Now I'm retired from all of that, but my Mac is still hard at work, mining alt-coins and doing it fairly competitively dispite the lack of support from the Alt-Coin-Community. The first thing I noticed in mining was that there are only 2 Mac based miners out there, that obey the Mac coding minimums as required by Apple, GUIminer is one, athough it doesn't do very well, and Asteroid.app (http://asteroidapp.com/) Asteroid App is also the only miner that will do scrypt mining, as opposed to Mac-GUIminer which holds the poclbm SHA256 mining software only, dispite the abilities of it's Windows and Linux counterparts. Step 1) Download Asteroid App. Step 2) Open a mining account on MinCoinPool.com Step 3) Open AsteroidApp and set your GPU miners to the mincoinpool GETWORK server and port, with the credentials from your account. Step 4) Set AsteroidApp to open at Startup, and restart your Mac. Step four is the step that took me the most time to figure out. Even though I had stopped the miner from starting when it first opened, the app still leaves an insance of the minerd running in the background. When you change settings however, it attempts to open a new process for minerd miner which is, lets just say, not healthy for your mac. By rebooting once you have your settings completed, you eliminate this bottleneck hazzard and AsteroidApp will restart and run smoothly on the new settings. -Jarl
GPU Mining with GUIMiner in Windows What Youâ€™ll Need GPU (for this particular tutorial) - â€œThe workhorse. Think of it as the miner with a pickaxe or the heavy drilling machinery.â€ Radeon GPUs are recommended over Nvidia, they are much more efficient at mining. You can still mine with an Nvidia card, but your hashrate (essentially how fast your card can process the algorithm) will be lower. Check out this link to compare the expected hashrate for scrypt mining on various hardware: https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison Note: The link says â€˜Litecoinâ€™ hardware, but it applies for MinCoin as well as they are both based on the same scrypt algorithm. For AMD cards: Ensure you have updated to latest drivers for your card: http://support.amd.com/us/gpudownload/Pages/index.aspx You will also need to download the AMD SDK to run GUIMiner, can be found here: http://developer.amd.com/tools/hc/AMDAPPSDK/downloads/Pages/default.aspx For Nvidia cards: Ensure you have updated to the latest drivers for your card: http://www.nvidia.com/Download/index.aspx?lang=en-us. You will also need to download and install the Nvidia CUDA toolkit to run GUIMiner, can be found here: https://developer.nvidia.com/cuda-downloads Computer with Windows (for this particular tutorial) MinCoin Client Download the client from min-coin.org. For Windows, youâ€™ll want to click on one of the top two links. Once finished downloading, install and run. The first time you fire up the client it will need to connect to the network, and download the blockchain. While itâ€™s downloading, a green bar on the bottom will show its progress. Once finished, a green check mark will appear in the bottom right of the window. Mining software â€“ â€œThe Mining Foreman: Instructs the miners on where and how to mineâ€ For the sake of simplicity, we will download the latest â€˜GUIMiner â€“ scryptâ€˜ client. Hereâ€™s a link to the forum post at bitcointalk.org; https://bitcointalk.org/index.php?topic=150331.0 Click on one of the highlighted download links. Extract the .zip file wherever you wish.
