# Living Village macOS 测试版

本目录是从 Linux 主机交叉生成的 macOS DesktopGL self-contained 测试版，不是最终游戏验收结论。M3 长期批验仍独立进行；本包没有在 macOS 实机启动验证，也没有声称签名或公证。

## 选择架构

- Apple Silicon（M1/M2/M3/M4 等）：使用 LivingVillage-osx-arm64.zip。
- Intel Mac：使用 LivingVillage-osx-x64.zip。
- 每个 ZIP 内含一个可拖入 /Applications 的 .app。包内包含 .NET runtime、MonoGame SDL2/OpenAL native dylib，不依赖用户另装 dotnet。

## 首次打开

包未签名、未公证。解压后将对应 .app 拖入“应用程序”，首次打开时在 Finder 中右键该单个应用并选择“打开”，再确认“打开”；若系统显示“无法打开”，先尝试启动一次，再到“系统设置 → 隐私与安全性”对该应用选择“仍要打开”。

不要关闭 Gatekeeper，也不要使用全局禁用安全检查的命令。

## 存档与结构

- 启动器位于 Contents/MacOS/LivingVillage，会定位自身目录后启动同目录的 self-contained apphost。
- 默认存档位于 ~/Library/Application Support/Living Village/living-village.save；可用绝对路径覆盖 LV_SAVE_PATH，相对路径相对 app bundle 根目录解析。
- Contents/Info.plist、Contents/MacOS、Contents/Resources 均包含在包中；SDL2/OpenAL dylib 会随发布文件放在可执行文件同目录。

## 证据

- PACKAGE-INFO.txt：source commit、RID、self-contained、签名/公证状态。
- SHA256SUMS.txt：ZIP 的 SHA-256 与字节数。
- verification/：dotnet publish 日志、Mach-O 架构检查和 ZIP 完整性检查。
- Linux 主机没有 hdiutil 时不生成 DMG；若生成，DMG 也不代表签名或公证。
