applescript - 如何在 Applescript 中将 UI Elements Enabled 设置为 true？

Question

tell application "System Events"
    if UI elements enabled is true then
        tell application "System Preferences"
            activate
            set current pane to pane id "com.apple.preference.universalaccess"
            display dialog "This script requires access for assistive evices be enabled." & return & return & "To continue, click the OK button and enter an administrative password in the forthcoming security dialog." with icon 1
        end tell
        set UI elements enabled to true

        if UI elements enabled is false then return "user cancelled"
        delay 1
    end if
end tell

当我运行这个时，我收到一个错误。 “无法将应用程序启用的 UI 元素设置为 true”

任何想法为什么会发生这种情况？

自 OS X Mavericks 以来，启用的 UI 元素是只读属性。尝试这个:

tell application "System Events"
    if not UI elements enabled then
        display dialog "This script requires access for assistive devices be enabled." & return & return & "To continue, click the OK button and enter an administrative password in the forthcoming security dialog." with icon 2
        if button returned of result is equal to "OK" then
            do shell script "sudo sqlite3 'Library/Application Support/com.apple.TCC/TCC.db' 'insert or replace into access values (\"kTCCServiceAccessibility\",\"com.apple.ScriptEditor2\",0,1,0,null);'" with administrator privileges
        end if
    end if
end tell
