Suspicious Package (An Application for Inspecting macOS Installer Packages)


  • One contains a useful and well-designed product, which can’t be easily installed using drag-and-drop.
  • One contains well-intentioned software that will nevertheless splatter pieces all over your startup disk.
  • One contains a vital component — like a scanner driver — but will also install a handful of annoying, unwanted applications that the driver vendor distributes in return for “promotional consideration.”
  • One contains malware that will infest your system and your network, and probably ruin your week.

Which one is which? ¯\_(ツ)_/¯ The answer in macOS has traditionally been “install it and find out!”

The built-in security features of macOS — such as Gatekeeper, package signing and most recently, notarization — might rule out malware … if you’re lucky. But there’s still a huge gray area between that and a well-designed package.
