Suspicious Package overview

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 version 4.7

  • Adopted the "Liquid Glass" appearance for macOS 26 and beyond. We're still not fans, even with the changes in Golden Gate, but we've reached the point of either giving in or giving up — and we're not prepared to give up just yet.
  • Fixed a problem where, on macOS 26, the Edit > Find in Script results didn't clearly indicate which scripts were not matched by the search. That is, on Tahoe, the unmatched scripts were disabled in the scripts browser, but they looked the same as the enabled ones.
  • Fixed a problem in the rule-based Edit > Search in Package UI, where it wasn't possible to use the right/left arrow keys to scroll through a long text field. (Unfortunately, we can't do anything about the size of the text fields here, since the macOS standard rule editor does what it wants, but we can at least make it possible to see the rest of the text.)
  • Fixed a bunch of long-lingering issues with how the Quick Look Preview is displayed, especially when using View > Show Preview in the Finder List or Column views. You can now reliably hover your pointer over any truncated text to see the full version, and scroll the preview down to view any additional information. (Previously, the only way to get at any cut-off information was to enlarge the preview pane itself.)
  • Fixed a longstanding bug where clicking Open in Suspicious Package from the Quick Look Preview might fail with "The document could not be opened. You don't have permission." This could occur if the package was in some TCC-protected location (e.g. your Documents folder) to which Suspicious Package was not previously given access. The same problem could occur when using the spkg command line tool on a package in such a location. Either way, Suspicious Package will now receive whatever access was available to the Quick Look Preview or the spkg tool, and should be able to open it properly.
  • Fixed a bug where a package-containing disk image might be prevented from ejecting, even after the corresponding window in Suspicious Package has been closed.
  • Fixed a bug where the window would get ridiculously wide if the package file had a really long name.
  • Removed support for macOS 13 (Ventura) and macOS 12 (Monterey).

Unfortunately the new version is for Big Sur or higher. But I highly recommend this app for anyone "curious" or "paranoid" You can see inside installers and make your digital life a bit more secure.

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.
