title: X11 forwarding not working on MAC OS Mojave
body: <p>I'm having trouble getting x11 forwarding when I ssh into a linux machine. When I do ssh -X username@serveraddress, I get the following error appearing after I successfully login: /usr/bin/xauth:  error in locking authority file /home/username/.Xauthority . I have tried to follow the fixes suggested to this problem on stackoverflow but they don't seem to work.</p>
  
  <p>I have tried editing ~/.ssh/config so that it looks like this:</p>
  
  <pre><code>Host *
      XAuthLocation /opt/X11/bin/xauth
  </code></pre>
  
  <p>This does not fix the problem. Any ideas would be greatly appreciated.</p>
