Enable Screen Mirroring show in menubar

[elliots]

Hi,

Our fleet has just jumped from Catalina to Monterey and our users are struggling to locate the screen mirroring "Show in menu Bar" tickbox. 

Ideally I would just like a script to enable this or our users. 

I have tried

defaults write ~/Library/Preferences/ByHost/com.apple.controlcenter.plist ScreenMirroring -int 18

but it doesn't seem to work.

weirdly sound and bluetooth work though which are controlled inside the same plist. 

e.g: defaults write ~/Library/Preferences/ByHost/com.apple.controlcenter.plist Sound -int 18

anyone got any ideas how the ScreenMirroring preference can be set via terminal script?

Cheers,

ES

Update: 

I have managed to enable the tickbox with:

defaults write com.apple.airplay showInMenuBarIfPresent -bool true

However I have another hurdle. Is it possible to change from the default: "when active" to "always" so it always displays in the menubar?

@elliots :

I found this in the MacAdmins slack...credit to @nstrauss - noting it's "per user":

#!/bin/zsh

logged_in_user=$(scutil <<< "show State:/Users/ConsoleUser" | awk '/Name 😕 && ! /loginwindow/ { print $3 }')
user_home=$(dscl . -read /users/$logged_in_user NFSHomeDirectory | cut -d " " -f 2)

sudo -u "$logged_in_user" /usr/bin/defaults write "$user_home"/Library/Preferences/ByHost/com.apple.controlcenter.plist ScreenMirroring -int 18
sudo -u "$logged_in_user" /usr/bin/defaults write "$user_home"/Library/Preferences/com.apple.airplay.plist showInMenuBarIfPresent -bool true

sudo killall "ControlCenter"

Works here in macOS 12.2 beta I'm running, so give it a shot....

Dang it...where the "smiley" is, change to : / (with no space in between)!!!

Someone tell me why pasting into code gives me emojis?  Or rather, how do I stop that!

@scottb  Apologies, Scott, this is a bug and we are working to resolve it as quickly as possible. 😀

Thank you, @CalleyO - I meant to file it and forgot!  Appreciate the heads-up.

Oh Thankyou! that worked a treat.
