title: Cannot change permissions for dtrace on MacOS
body: <p>I was looking at <a href="https://opensourcehacker.com/2011/12/02/osx-strace-equivalent-dtruss-seeing-inside-applications-what-they-do-and-why-they-hang/" rel="nofollow noreferrer">this article</a>.</p>
  
  <p>It recommends allow the usage of dtrace without root for current user, so I run:</p>
  
  <pre><code>$ sudo chmod u+s /usr/sbin/dtrace
  Password: # I enter in my password
  chmod: Unable to change file mode on /usr/sbin/dtrace: Operation not permitted
  </code></pre>
  
  <p>Does anyone know if I should, and how I should, allow dtrace to run without root permissions?</p>
