And, while OS X is pulling up the rear when it comes to supported OS’s for bitcoin mining, hopefully I’ve demonstrated some viable options for getting your feet wet with mining on OS X. These are exciting times for crypto currency, whether you’re a geek or a speculator or merely a bystander. Compare that to 400 Mh/s with GUIMiner and 370 Mh/s with BitMinter and you can see why these command-line miners are preferred over their GUI counterparts.
CGMINER MAC FULL
Refer to the projects on Github for full documentation of the available command-line parameters.Īs you can see from the average in the upper-left of each miner’s output, with cgminer and bfgminer I average 460 Mh/s.
CGMINER MAC PASSWORD
So, my command-line using cgminer with the BitMinter pool would look something like this:Ĭgminer -k diablo -o -u username_workername -p password -I 9īfgminer -k diablo -o -u username_workername -p password -I 9 -no-opencl-binaries I find on OS X that using -k diablo gives the best performance. Passing in -I 9 is a safe value for having the miner use as much of your graphics resources as possible to mine.
CGMINER MAC PC
If you pass in -I d then the miner will use less resources so you can use your PC (think D for Desktop). Other notable command line parameters are -I (for intensity) and -k (for kernel). This is not necessary with cgminer as it detects OS X and applies the same workaround automatically. If you have multiple graphics cards you’ll want to use the –no-opencl-binaries parameter with bfgminer to avoid a crash on startup. You can either run them without any command line parameters and fill in the prompts for mining pool URL and credentials or you can use the following format to specify your pool: Usageīoth cgminer and bfgminer are command-line utilities. I’d also recommend using brew doctor to diagnose any issues.
CGMINER MAC INSTALL
If you run into errors installing the above formulas you can try running brew install with the –debug –verbose parameters to find where things went wrong. You can visit the Github repository to view the package contents. If you specify the –HEAD (two dashes) parameter for brew install then the latest source-code will be pulled for the miner from Github rather than using the latest official release. Once Homebrew is successfully installed, you can run the following commands to install cgminer and bfgminer: While that was necessary at the time, after some reading and experimenting with Homebrew I was able to create packages (called formulas with Homebrew) for installing cgminer and bfgminer on OS X 10.8.
CGMINER MAC CODE
In my previous post I indicated that it was necessary to compile cgminer and bfgminer from their source code in order to install them on OS X. Make sure you address any errors or warnings before proceeding as they may prevent the miners from installing. Open up Terminal.app and run the following command (from the Homebrew homepage):Īfter you install Homebrew, make sure you run the following command (as the installer should instruct you): It is similar to MacPorts for OS X or apt for Linux.
Homebrew is a package manager for OS X that provides a sane way of installing *nix tools, libraries, and their dependencies. If the text next to Xcode Command Line Tools says Installed, carry on to the next step. Click the Downloads tab and then click Install next to Command Line Tools. Launch Xcode and then click the Xcode>Preferences menu item.
Next you’ll need the Xcode Command Line Tools. Xcode is a free download from the Apple App Store. To get started, you will need to install the Xcode.
Both miners offer similar performance in my experience. However, I have had good luck with both tools and have worked with both authors in order to fix a crash ( cgminer, bfgminer) related to multiple GPU’s on OS X and have no complaints whatsoever. Now, I have no dog in this fight, but my understanding is that the teams aren’t on great terms. The bfgminer project is a fork of the cgminer project. These are native C miners and, paired with the right kernels, their performance exceeds the other two miners by quite a wide margin. For that you’ll want to look at cgminer and bfgminer. However, while these miners are relatively easy to install and use, they do not offer the best performance when it comes to hash rates. In my previous two posts in this series I introduced two easy-to-use bitcoin miners for OS X: BitMinter and GUIMiner.
