macOS 输入 df -h 命令，为什么会出现微信读书？

如下所示：

mount 看看

[yslin]

@slowmist
```bash
(base) ➜ ~ umount /Applications/微信读书.app/Wrapper
umount(/private/var/folders/6t/7stlwdtn5yj5x_hq3d9mrhlh0000gn/X/1B51C8FB-A8C3-5711-BE2D-278BD23492A8): Resource busy -- try 'diskutil unmount'

微信读书是 ipad 版的，感觉是运行的时候虚拟挂载到文件系统了？我试了一下小红书也是这样，应用退出等会儿再执行命令就没了

[yslin]

@qczone 刚才试的时候微信读书是退出的，我再打开关掉试试

[yslin]

@qczone 奇怪，依然存在

@qczone
@yslin MacOS 能添加 iPad/iPhone app 小组件，所以会出现这个。

@takumiOnTheMoon 听起来很有道理
