An Application for Inspecting OS X Installer Packages
Do you know what files that OS X Installer package actually installs?
Do you know what scripts it runs during installation, and what they do?
Do you know who the package really came from?
With Suspicious Package, you can answer these questions and more. Maybe you're quite literally suspicious of a package you've downloaded. Or perhaps you're just curious about what some package does. Or maybe you want to find out after the fact exactly what files a package scattered across your computer. Whatever the reason, Suspicious Package allows you to see inside an installer package. (And it's completely free.)
Suspicious Package is actually both an OS X application ...
... and a plug-in for the Quick Look feature of OS X.
Use it whichever way you find most convenient.
