First off you need Apple's Xcode (at least version 7, preferably 8.x) and the Xcode Command Line Tools: https://itunes.apple.com/us/app/xcode/id497799835?mt=12 And Homebrew: http://brew.sh/ And this is the list of brew packages you'll need installed: ```shell brew tap discoteq/discoteq; brew install flock brew install autoconf autogen automake brew tap homebrew/versions; brew install homebrew/versions/gcc5 brew install binutils brew install protobuf brew install coreutils brew install wget ``` Get all that installed, then run: ```shell git clone https://github.com/j-cimb-barker/komodo.git cd komodo git checkout dev ./zcutil/build-mac.sh ``` To build a distributable version of komodo then run the makeDistrib.sh script after building. When you are done building, you need to do a few things in the [Configuration](https://github.com/zcash/zcash/wiki/1.0-User-Guide#configuration) section of the Zcash User Guide differently because we are on the Mac. All instances of `~/.zcash` need to be replaced by `~/Library/Application\ Support/Zcash` The fetch-params.sh script, however, has already been altered to fetch the proving keys into the correct directory to conform to Mac specific naming conventions. Happy Building
