title: "conda init" for conda 4.6 not working on macOS mojave
body: <p>The conda 4.6 releaser announcement says to run </p>
  
  <pre><code>conda update conda
  </code></pre>
  
  <p>and then</p>
  
  <pre><code>conda init
  </code></pre>
  
  <p>The update works fine, but the init gives an error:</p>
  
  <pre><code>$ conda init

  <p>I don't have a .bash_profile. I do have a /Users/xxxxxx/.profile, but it's not directly executable with or without sudo.</p>
  
  <p>Any thoughts?</p>
