SlowQ v1.0.5 · 慢Q

自定义磁盘卷图标:挂载 DMG 后,桌面与 Finder 里显示一枚专属安装盘图标。
Custom volume icon for the disk image.

✨ 本次改动

自绘的卷图标

之前挂载 DMG 后显示的是系统通用磁盘图标(或直接套用 App 图标)。现在改为专门绘制的安装盘造型:

  • 圆角金属机身 + 顶部高光渐变
  • 底部接缝分色,带一枚绿色电源指示灯(含光晕)
  • 机身中央是白色蜗牛 logo(深色底上清晰可辨)
  • 配色与安装界面横幅一致,整条安装体验视觉统一

由 tools/gen-volumeicon.swift 用代码绘制,无外部设计资源;输出 1024px 底图后经 sips + iconutil 生成 .VolumeIcon.icns。

应用本身与 v1.0.4 完全一致,本版只更新安装盘外观。

🐛 顺带修掉的两个打包坑

这两个问题都只有实际制作镜像时才会暴露,已在新脚本里绕开并写进注释:

1. Finder 会删掉 .VolumeIcon.icns

若在 hdiutil create 之前把卷图标放进暂存目录,Finder 打开该卷设置视图时会把它删除,最终镜像里就没有卷图标了。改为先只在临时目录生成 icns,等 Finder 设置完视图后再写入已挂载的卷。

2. 残留同名卷会让退盘静默失败

制作过程中若留下 /Volumes/SlowQ 1 这类残留挂载,Finder 里会出现两个同名磁盘,eject disk "SlowQ" 无法定位、静默失败,进而回退到强制卸载 —— 而强制卸载会丢失刚设置好的视图。现在脚本在开始前会预清理同名残留卷,并在写入卷图标后 sync 强制落盘。

顺带说明为什么卸载必须交给 Finder:直接 hdiutil detach 时 Finder 会用内存里的旧快照覆盖 .DS_Store(实测字节数从 10244 掉回 6148,背景图与图标大小全丢),只有 Finder 自己退盘才会先刷盘。

⚠️ 首次打开必读

本应用未经 Apple 开发者签名与公证,macOS 会拦截首次启动。执行一次:

xattr -dr com.apple.quarantine /Applications/SlowQ.app

或在 Finder 里右键 → 打开 → 弹窗里再点 打开。

🔑 授予辅助功能权限

系统设置 → 隐私与安全性 → 辅助功能 → 勾选「慢Q」。未授权时菜单栏图标仍会显示,菜单里也提供了直接跳转设置的入口。

升级提示:覆盖安装后辅助功能授权可能失效(adhoc 签名随二进制变化)。若拦截不工作,执行 tccutil reset Accessibility com.slowq.app 后重新勾选。

Custom volume icon

Mounting the disk image now shows a purpose-drawn installer-disk icon instead of the generic system volume icon:

  • Rounded metallic body with a top gloss gradient
  • A seam near the bottom with a green power LED (with glow)
  • The snail logo rendered white in the centre so it reads clearly on the dark body
  • Colours matched to the installer banner for a consistent experience

Drawn entirely in code by tools/gen-volumeicon.swift; a 1024px master is converted to .VolumeIcon.icns via sips + iconutil.

The app itself is identical to v1.0.4 — this release only changes how the disk image looks.

Two packaging bugs fixed along the way

1. Finder deletes .VolumeIcon.icns — if the icon is placed in the staging folder before hdiutil create, Finder removes it when it opens the volume to apply the view settings, so the final image ends up with no volume icon. The script now generates the icns in a temp directory and copies it onto the mounted volume after Finder has done its work.

2. A stale same-named volume makes ejecting fail silently — a leftover mount such as /Volumes/SlowQ 1 makes Finder see two disks with the same name, so eject disk "SlowQ" cannot resolve and fails without an error, which falls back to a forced detach that discards the view settings. The script now pre-cleans stale mounts and runs sync after writing the icon.

Reminder on why the volume must be ejected by Finder: a plain hdiutil detach lets Finder overwrite .DS_Store with its stale in-memory snapshot (measured: 10244 bytes back down to 6148, losing the background and icon size). Only Finder's own eject flushes first.

Download the .dmg or .zip below (universal binary, macOS 13+). Clear the quarantine flag once, then grant Accessibility permission. After upgrading over an older build the grant may need re-applying via tccutil reset Accessibility com.slowq.app.
