What is Suspicious Package for Mac

With Suspicious Package, you can find out important information about those package files you download. 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?... 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 now actually both an OS X application,... and a plug-in for the Quick Look feature of OS X.

What's new in Suspicious Package

Version 4.0:
  • Refreshed the UI to better fit the aesthetic of the Central Coast era of macOS.
  • Compatibility updates for macOS 12 (Monterey).
  • Added support for the new "large payload" feature of macOS Installer packages. This feature, enabled by the ‑‑large‑payload option of pkgbuild(1) or productbuild(1), is required if the package delivers any single file that exceeds 8 GB in size. Suspicious Package will now properly analyze and export from such packages, even when running on macOS 11 or earlier (although only the macOS 12 Installer will properly install the package).
  • Fixed a crash that would occur - at least on some beta versions of Monterey - when a matching receipt is found for the opened package.
  • Added information about the package format to the Package Info tab: this identifies the structure of the package (such as "Distribution Archive" or "Component Package") and may be relevant if you are using certain mass deployment mechanisms. However, if you are just going to double-click the package to open the Installer, this is probably not something you need to be concerned with.
  • Added the ability to search the installed files based on the POSIX mode of the file or folder. For example, you can use a rule like file mode sets any bit in mask 0022, which will show any files or folders that are installed as writable to group or everyone. See this FAQ entry for detailed instructions and examples.
  • Added the ability to search the installed files based on the component package that installs it. This was possible before using a package ID rule, but required re-entering the component package identifier; the new component package rule type has a pop-up to make selection easier, and package names as well as identifiers.
  • Added an option in Suspicious Package > Preferences > General to Show PackageInfo files on All Scripts tab. Turn this on to see the original PackageInfo XML file from each component package, grouped with the scripts on the All Scripts tab. Suspicious Package already interprets these files, and presents the information in them in what we hope is a more useful way. But if you need to see the underlying file, this makes it more convenient.
  • Attempted to improve the handling of the review issue flagging that "one or more scripts in this package may be run when the macOS Installer opens..." Specifically, the Show Scripts That Run on Open button wouldn't actually show the Distribution file, which is often necessary for understanding what exactly will run. Also, Suspicious Package will now give you the option of turning on the preference that controls showing the Distribution.
  • Fixed a bug that could cause the count of installed items on the Package Info tab to be incorrect, usually by a small number. This was a longstanding discrepancy related to the way that package Bom files get read and merged.
  • Fixed display of some unusual and archaic item names, such as "Icon^M".

Very impressed. Software is exceptionally well designed, easy to use, and teaches the user about how installer packages are created though Suspicious Package's use. While I love Pacifist, Suspicious Package (SP) has become my go-to and I set it as my default '.pkg' file opener. It would be awesome if SP could have a setting where you drag your favorite anti-virus software into an image well and it would then offer the ability to open whatever package you are analyzing into that AV software whenever you run SP. (sub launch with file)

Essential tool to see what sorts of sneaky sludge an app may want to stuff into your system.

Love this app. Very convenient way to figure out what will be installed by a .pkg beforehand. I mostly use it through QuickLook, but the app itself provides additional features that are quite handy too.

Simple, effective, free, and the developer allows distribution in enterprise. I wish charlessoft would rope this baby in to replace their Pacifist plug-in. :) Don

I'd forgotten that I installed this some time ago. But the installer will detect an older version and write the new version over the old, in the same location, to prevent duplication. Very cool. SP is especially useful to find software install locations, which can be useful when you wish to uninstall something. I have to agree, five stars.

A very useful pkg albeit still prefer using unpkg because it creates a copy of the actual package which for me makes it easier to uninstall if the software is not what i want. I still rate this software at 5 because it gives me a fast look at what is installed and where. Perhaps making a screen shot would help me later on if i would need to uninstall a software that was installed by .pkg.

Works well in Lion (10.7.1). I installed it in the top-level QuickLook folder instead of my User folder & didn't have to log out & in again. Gives lots of good info on packages without having to open them. Love it, love the price.

Mysteriously stopped working on Leopard (10.5.8), maybe after the Safari 5 update. Still works fine on Snow Leopard (1.6.4) and Safari 5.

The screenshot is self-explaining. Very useful to those who are not too lazy to think twice before installing something.
