title: Terminal MAC OSX uptime command showing 2 users
body: <p>Hi I am pretty new to programming. </p>
  
  <p>I have started using terminal on my mac. </p>
  
  <p>I tried using the uptime command on localhost and it says there are two users. However I'm the only one logged onto my laptop.</p>
  
  <p>Why does it say 2 users?</p>
