macOS Installer "Show Files" only "The file listing isn't available"


The Installer has a build-in file browser under file menu. But it only shows "The file listing isn't available".

In the installer log:

Installer[82159]: PFPackage::packageWithURL - can't instantiate package: /Users/*/Downloads/Install.pkg

Solution

  • The problem is the space in the embedded Installer package. Changing "Letter Opener.pkg" to "Letter-Opener.pkg" fixes it.
