How to Check Packages for Expired Certificates on Mac OS: A Complete Guide

Are you a Mac user who frequently downloads software packages or updates? If so, you may encounter a common issue where the package installer or update file has an expired certificate, preventing successful installation.

In this guide, we will show you how to check the signature status of packages in Mac OS X and determine if they are valid, expired, or unsigned. By following these steps, you can avoid installation errors and ensure the security and integrity of the packages you download.

How to Check Package Signature Status in Mac OS X

Mac OS X comes with a powerful command-line utility called pkgutil, which allows you to check the signature and certificate status of any package. Here’s how you can use it:

1. Launch Terminal from /Applications/Utilities/.

2. Use the following command: pkgutil -checksignature /Path/to/Example.pkg

3. Press Enter to see the result: whether the signature is valid, expired, or if there is no signature at all.

For example, if you have a package like “OSXUpdateCombo10.10.2.pkg” and its signature has expired, you will receive an error message. On the other hand, some packages may not have any signature, which you should handle with caution, especially if they are from third-party sources.

You can also use wildcards to check multiple package files at once. Simply input pkgutil checksignature /Path/to/*.pkg to quickly determine the certificate status of multiple packages.
