MacOs Catalina Second Screen (update)


Well, having resolved my second screen issues yesterday and worked for several hours without issue, I shut down my computer.

This morning there’s no second screen again.

A really simple solution

So, here’s my really simple solution – hope it helps somebody out there.

  • Pull out the cable
  • get an old Apple Tv
  • attach the screen to that
  • get a mains socket network extension pack with ethernet cable sockets
  • connect to your main router through the mains
  • wire your network socket to your Apple Tv
  • use airplay to add your Apple Tv as your second screen

Job Done!
