优先方案：原生播放命令实现（无UI依赖，稳定性最高） #

绝大多数适配系统播放框架的应用（包括本地播放器、浏览器网页视频、主流流媒体桌面端）都支持原生播放控制接口，不需要定位UI元素即可直接操作：

5秒快进脚本 #

tell application "System Events"
    -- 获取当前正在播放的应用
    set activePlayers to every application whose has audio playback is true and playing is true
    if (count of activePlayers) > 0 then
        set targetApp to item 1 of activePlayers
        try
            tell application (name of targetApp)
                step forward by 5
            end tell
        on error
            -- 原生接口不兼容时兜底模拟媒体键操作
            key code 100 -- 快进媒体键
            delay 0.2
            key code 100
        end try
    end if
end tell

5秒快退脚本 #

tell application "System Events"
    set activePlayers to every application whose has audio playback is true and playing is true
    if (count of activePlayers) > 0 then
        set targetApp to item 1 of activePlayers
        try
            tell application (name of targetApp)
                step back by 5
            end tell
        on error
            key code 99 -- 快退媒体键
            delay 0.2
            key code 99
        end try
    end if
end tell

备选方案：动态UI定位实现（适配特殊场景） #

如果原生命令不支持你的播放场景，可以用动态属性匹配定位NowPlaying组件的进度条，不要使用UI浏览器抓取的静态路径，控制中心UI层级每次展开都会动态变化，静态路径极易失效：

前置要求 #

运行前需要给脚本编辑器/执行脚本的工具开启「系统设置-隐私与安全性-辅助功能」权限，DRM加密的受保护视频无法通过该方案控制。

5秒快进UI版脚本 #

tell application "System Events"
    tell process "ControlCenter"
        -- 展开NowPlaying面板
        click menu bar item "Now Playing" of menu bar 1
        delay 0.1
        -- 匹配进度条控件
        set playSlider to slider 1 of group 1 of window "Control Center"
        -- 计算5秒对应偏移量
        set totalTime to value of attribute "AXMaxValue" of playSlider
        set currentTime to value of playSlider
        set offset to 5 / totalTime * (max value of playSlider - min value of playSlider)
        set value of playSlider to currentTime + offset
        -- 收起面板
        click menu bar item "Now Playing" of menu bar 1
    end tell
end tell

5秒快退UI版脚本 #

仅需将上述脚本中set value of playSlider to currentTime + offset改为set value of playSlider to currentTime - offset即可。
