title: How to use "RVM --default" on MacOSX
body: <p>After using Ruby and Rails for quite some time now, I wanted to try RVM. Everything works fine, except for one thing:</p>
  
  <p>In a freshly opened Terminal <code>ruby</code> points to the system's ruby, despite the fact, that I used the <code>rvm --default</code> command.</p>
  
  <pre><code>user@terra ~ $ ruby -v
  ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10]
  user@terra ~ $ which ruby
  /opt/local/bin/ruby
  user@terra ~ $ rvm list
     ruby-1.8.7-p334 [ ]
  =&gt; ruby-1.9.2-p180 [ ]
  </code></pre>
  
  <p>Everything is fine after I call <code>rvm reload</code></p>
  
  <pre><code>user@terra ~ $ rvm reload
  user@terra ~ $ ruby -v
  ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.7.1]
  tmangner@terra ~ $ which ruby
  /Users/user/.rvm/rubies/ruby-1.9.2-p180/bin/ruby
  </code></pre>
  
  <p>I set up my <code>.bash_profile</code> as described in the documentation:</p>
  
  <pre><code>[[ -s "/Users/user/.rvm/scripts/rvm" ]] &amp;&amp; source "/Users/user/.rvm/scripts/rvm" 
  </code></pre>
  
  <p>That <code>--default</code> does not seem to work for me ...</p>
  
  <pre><code>user@terra ~ $ rvm use 1.9.2 --default
  Using /Users/user/.rvm/gems/ruby-1.9.2-p180
  user@terra ~ $ rvm default
  user@terra ~ $
  </code></pre>
  
  <p>I'm using Mac OS X Snow Leopard (10.6.6)</p>
