This program enables you to inspect macOS installer packages on your computer. The application might prove to be of good use if you download a suspicious installer package on your Mac and wish to know detailed information regarding its origin and contents.
Suspicious Package comes with a user-friendly interface, provides you with a detailed report based on found information, and is free of charge.
All you need to do is to go to File -> Open and import the installer package in question. The utility will immediately start analyzing the file and provide you with the information you need. An important advantage is that it allows you to check out the contents of your installer package files. You can see the files that are being stored in the installer package (click the files to reveal additional info) and use the integrated search utility to easily find the file of your interest.
My only problem with this application is the fact that it supports a small number of macOS versions (10.11+).
So, you should give this program a try if you're not running a machine that has an operating system version older than El Capitan (10.11).
v3.3 [Sep 19, 2017]
- Added support for macOS 10.13 (High Sierra). This included fixing a crash that might occur when closing windows, and correcting the way that revoked certificates are displayed (they had been shown as generically untrusted rather than as explicitly revoked).
- If a package has a verified signing time, Suspicious Package now shows that information when you use Window > Signature Details (Command-5). This is particularly interesting when the certificate would be otherwise considered expired.
- Fixed a problem where a prior install was (sometimes) not noted on the Package Info tab.
- The Suspicious Package app now tries harder to activate its Quick Look plug-in, especially after the app has been moved or updated, or after macOS has been updated.
- Removed support for OS X 10.10 (Yosemite) and OS X 10.9 (Mavericks).
- Updated the license agreement to be a bit more explicit, although it is still quite minimalist. Use Help > License Agreement to access it from within the app.
