AppleScript设置闲置15分钟关显示器报错求助

1. 语法错误修复及逻辑优化 #

原脚本的语法错误出在set currentPosition to get the mouse location这一行，AppleScript中获取鼠标位置无需get和the修饰，同时嵌套的tell application "System Events"会导致上下文冲突，以下是修复并优化逻辑后的脚本：

set frontApp to name of first application process whose frontmost is true
set mouseMoved to false
set idleMinutes to 0

repeat
    tell application "System Events"
        set currentPosition to mouse location
    end tell
    
    if currentPosition is not equal to {-1, -1} and currentPosition is not in {{0, 0}, {0, 1079}} then
        set mouseMoved to true
    end if
    
    if mouseMoved is false then
        set idleMinutes to idleMinutes + 1
        if idleMinutes >= 15 then
            tell application "System Preferences"
                activate
                set current pane to pane "com.apple.preference.displays"
            end tell
            tell application "System Events" to tell process "System Preferences"
                click button "Display" of tab group 1 of window 1
                delay 2
                click radio button "Turn off after: 15 min" of tab group 1 of window 1
            end tell
            tell application "System Preferences" to quit
            set idleMinutes to 0
        end if
    else
        set idleMinutes to 0
        set mouseMoved to false
    end if
    
    delay 60
end repeat

2. 更高效的替代实现 #

通过系统偏好设置操作界面易受语言、版本影响出错，推荐用pmset命令直接操作，更稳定可靠：

方式一：设置显示器自动关闭时间 #

set idleThreshold to 15
set lastMousePos to {-1, -1}
set idleCount to 0

repeat
    tell application "System Events"
        set currentMousePos to mouse location
    end tell
    
    if currentMousePos is not equal to lastMousePos then
        set lastMousePos to currentMousePos
        set idleCount to 0
    else
        set idleCount to idleCount + 1
        if idleCount >= idleThreshold then
            do shell script "pmset displaysleep 15"
            set idleCount to 0
        end if
    end if
    
    delay 60
end repeat

方式二：闲置15分钟后立即关闭显示器 #

set idleThreshold to 15
set lastMousePos to {-1, -1}
set idleCount to 0

repeat
    tell application "System Events"
        set currentMousePos to mouse location
    end tell
    
    if currentMousePos ≠ lastMousePos then
        set lastMousePos to currentMousePos
        set idleCount to 0
    else
        set idleCount to idleCount + 1
        if idleCount ≥ idleThreshold then
            do shell script "pmset displaysleepnow"
            set idleCount to 0
        end if
    end if
    
    delay 60
end repeat

错误原因说明 #

• get the mouse location违反AppleScript语法规范，正确写法为直接调用mouse location属性；
• 嵌套的tell application "System Events"会造成上下文混乱，拆分后可避免此类问题；
• 原脚本未实现累计闲置时间的逻辑，仅单次检查鼠标位置就执行操作，不符合“闲置15分钟”的需求。
