+## Troubleshooting

-### macOS 提示 "应用已损坏，无法打开"
+### macOS: "App is damaged and can’t be opened"

-由于本项目尚未购买 Apple 开发者证书进行签名（Notarization），macOS 的 Gatekeeper 安全机制可能会拦截应用的运行。请按照以下步骤解决：
+Without Apple notarization, Gatekeeper may block startup.

-1.  将下载的 `GoNavi.app` 拖入 **应用程序** 文件夹。
-2.  打开 **终端 (Terminal)**。
-3.  复制并执行以下命令（输入密码时不会显示）：
-    ```bash
-    sudo xattr -rd com.apple.quarantine /Applications/GoNavi.app
-    ```
-4.  或者：在 Finder 中右键点击应用图标，按住 `Control` 键选择 **打开**，然后在弹出的窗口中再次点击 **打开**。
+1. Move `GoNavi.app` to **Applications**.
+2. Open **Terminal**.
+3. Run:

-### Linux 启动报错缺少 `libwebkit2gtk` / `libjavascriptcoregtk`
+```bash
+sudo xattr -rd com.apple.quarantine /Applications/GoNavi.app

-GoNavi 的 Linux 二进制依赖系统 WebKitGTK 运行库。不同发行版默认版本不同：
+Or right-click the app in Finder and choose **Open** with Control key flow.

- Debian 13 / Ubuntu 24.04 及更新版本：通常为 WebKitGTK 4.1
- Ubuntu 22.04 / Debian 12 等：通常为 WebKitGTK 4.0
+### Linux: missing `libwebkit2gtk` / `libjavascriptcoregtk`

-如果启动时报错（如 `libwebkit2gtk-4.0.so.37: cannot open shared object file`），请按系统安装对应依赖后重试：
+GoNavi depends on WebKitGTK runtime libraries.
