title: Port is already in use - for any port on Mac
body: <p>So recently I got a Macbook and I have cloned my project on it which is a MERN stack application. The port in my <code>.env</code> is 5000. When I attempt to start up the server I get the error that the port is already in use.</p>
  <p>I figured &quot;hmm ok, i'll change it to 5100&quot;. That worked, but only for that time, the next time I tried to run it i got the same error for port 5100.</p>
  <p>Anyone have any idea what's going on?</p>
