Just a heads up that today, the installer certificates used to sign Apple OS installers (previous to Catalina) and update packages, will be expiring.

Any previous-to-this-month installer packages and OS installers (not Catalina, but earlier) will fail to run. They may report errors, or that the installer app is damaged.

Also, Apple has not updated all of the packages (ie ATM the 10.14.6 updaters, both regular and Combo, are expiring today. They're on it, but...)

I blogged in more detail about this here:
The Apple Packagepocalypse, 2019 Edition

You're going to need to audit ALL of your packages from Apple, potentially redownloading them (Suspicious Package is an incredibly useful tool for this). You're also going to need to re-download the Mojave/High Sierra/Sierra et. al. installers from Apple and, if you have any USB OS installers created, re-create them.

Hi All, I am in the middle of deploying macOSUpd10.14.6Supplemental2.pkg and SecUpd2019-005HighSierra.pkg. As of the 24th, all computer that ran either one of these updates returned this in Jamf Pro: "Installation failed. The installer reported: installer: Package name is Security Update 2019-005
installer: Certificate used to sign package is not trusted. Use -allowUntrusted to override." as pointed out above, this is the Cert expired issue. Where can I get the updated security updates from? I need to be able to download them from an Apple site.
