+首次进入「设备与应用」，如果没有可用 HDC，页面会显示安装引导：
+
+1. 点击「前往华为官网下载」，在浏览器打开 [Command Line Tools 官方下载页](https://developer.huawei.com/consumer/cn/download/command-line-tools-for-hmos)。Apple Silicon 选择 Mac (ARM64)，Intel 选择 Mac (x86)，按官网提示登录华为账号并下载。
+2. 完整解压 ZIP，点击「选择已解压的工具目录」。可选择包含 `command-line-tools` 的解压目录、`command-line-tools` 本身，或其 `toolchains` 目录；插件定位 HDC、运行版本检查，成功后保存路径。错误选择和取消不会覆盖已有配置。
+3. 手机连接 USB，启用开发者模式与 USB 调试，解锁并允许这台 Mac 的调试请求。配置成功后自动检查设备；「刷新连接」也会重新检查工具，支持启动后才安装到 PATH 的 HDC。

+请保留完整的工具目录及同目录依赖库，插件不重打包官方 SDK。选择路径保存在插件自己的数据目录中；工具被移动、删除或无法运行时重新显示安装引导和原因。工具准备完成前隐藏空设备列表及不可用的管理面板，文件传输仍可直接使用。管理页明确选择 HDC 设备，不根据 MTP USB 地址猜测二者对应关系。
