title: ln: /usr/bin/php: Operation not permitted OSX 10.11
body: <p>I use PHPStorm on OSX with PHPUnit and Laravel.</p>
  
  <p>When I go inside my project from the <strong>PHPStorm console</strong> and type:</p>
  
  <pre><code>$ php --version
  
  PHP 5.5.29 (cli) (built: Sep  9 2015 00:26:40)

  $ which php
  
  /usr/bin/php
  </code></pre>
  
  <p>From my terminal:</p>
  
  <pre><code>$ php --version
  
  PHP 5.6.16 (cli) (built: Nov 27 2015 21:37:15)

  $ which php
  
  /usr/local/php5/bin/php
  </code></pre>
  
  <p>The above I installed.  I have edited my <code>PATH</code> to use it.</p>
  
  <p>Now I want to change the PHP version inside my PHPStorm. </p>
  
  <p>I tried editing composer.json:</p>
  
  <pre><code>"require": {
      "php": "&gt;=5.6.16",
  </code></pre>
  
  <p>and then running update:</p>
  
  <pre><code>$ composer update
  
  Your requirements could not be resolved to an installable set of packages.
  
    Problem 1
      - This package requires php &gt;=5.6.16 but your PHP version (5.5.29) does not satisfy that requirement.
  </code></pre>
  
  <p>I also tried to create a symbolic link . </p>
  
  <pre><code>$ sudo ln -s /usr/local/php5/bin/php /usr/bin/php
  </code></pre>
  
  <p>It fails with:</p>
  
  <pre><code>ln: /usr/bin/php: Operation not permitted
  </code></pre>
  
  <p>I am not sure what to do.  I would like to update Php to 5.6.16.</p>
