error "System Events got an error: Can’t get group 1 of window "Control Center" of application process "ControlCenter". Invalid index." number -1719 from group 1 of window "Control Center" of application process "ControlCenter"

This script worked just fine before I upgraded to Monterey, now it's getting stuck for some reason I can't figure out. Any ideas?

Answer 1

In macOS Monterey, using the AppleScript code in your question, I was able to get it to work by removing the tell its group 1 statement and its closing end tell statement, e.g.:

tell application "System Events"
    tell its application process "ControlCenter"
        tell its menu bar 1
            click its menu bar item "User"
        end tell
        
        tell its window "Control Center"
                set btns to its buttons
                repeat with btn in btns
                    if name of btn = "BrilliantCorners" then
                        click btn
                    end if
                end repeat
        end tell
