I need to mirror the display on my Macbook and on the external monitor I'm using. To clarify, I need both screens to show the same thing.
All the support forums and articles online say to use the Arrangement tab in Apple menu > System Preferences > Displays. However, on my Macbook (the 2020 version) there is NO arrangement tab!
Can anyone help?
MacBook Air 13″, macOS 11.2
As you already know, The arrangement option only shows up if the Mac detects that an external display has been plugged in. Your display appears to have been connected properly since you are using it while the lid is closed on the MacBook Air. Try unplugging and replugging in the display (while it's turned on and the MacBook's lid is open) and also try clicking the Detect Displays button to rescan for secondary monitors

Your MacBook Air must be successfully connected to the external display to show the arrangement option in System Preferences. Are you connected to your external display with the right cable/adapter?

Hi Axel. Yes, I'm definitely successfully connected because I'm using the external monitor to type this. I have my laptop closed so that the screen is carried over to the monitor. But I would like to be able to leave the laptop open and still use the external monitor as my main screen.
Although I'm successfully connected to the external display, the "arrangement" tab isn't showing...
