我在 MacOS 上安装 DMG 打包应用程序时遇到了一个奇怪的问题。以下是我所知道的，但我仍然不知道出了什么问题。
我尝试使用skype或inkscape在 MacOS (10.13.4) 上安装类似的东西
brew cask install skype --debug
但它挂起，输出如下。

所以我手动尝试了最后一行
/usr/bin/hdiutil attach -verbose -debug -plist -nobrowse -readonly -noidme -mountrandom /var/tmp/ /Users/hwwu/Library/Caches/Homebrew/Cask/skype--8.22.0.2.dmg
它挂起并显示

两者都brew doctor没有brew cask doctor问题的迹象。我还禁用了 LittleSnitch 防火墙。我没有安装防病毒程序。安装其他DMG相关包都有这个问题。我已经有一段时间无法安装任何东西了。在我看来，这是一个hdiutil或系统问题，而不是任何自制错误。sudo没有帮助，它以某种方式显示“未知的 UID”。
但是，通过双击下载的 DMG，它就可以正常工作，并且安装也很好。
请帮忙。
