To download / install on MacOSX, you can do the following steps or try the homebrew steps below:

1. Goto a directory you can write to:

   cd ~

2. get composer:

   curl -sS https://getcomposer.org/installer | php

3. move composer into a bin directory in your $PATH var:

   sudo mv composer.phar /usr/local/bin/composer

4. double check composer works

   composer about

5. (optional) Update composer:

   sudo composer self-update

Homebrew

brew update
brew tap homebrew/homebrew-php
brew tap homebrew/dupes
brew tap homebrew/versions
brew install php55-intl
brew install homebrew/php/composer
