I just wanted to point out that version 19.012.20034 of Acrobat no longer works on 10.11, as you can see on the release notes here:
19.012.20034 Added support for: Win Server 2019 Dropped support for: Mac OSX 10.11
I haven't tested this with Reader yet, but an Acrobat Pro patch policy will need any 10.11 Macs excluded from the scope, since the definition still states the minimum OS version is 10.11. I can confirm that this version fails to install on any 10.11 Macs.
Also, sorry to jump on the "patch management is mismanaged" bandwagon, but how did this get approved given the process for updating software titles that Jamf outlined here?
The update is downloaded, installed, and run on virtual machines with different macOS versions: 10.9, 10.10, 10.11, 10.12, 10.13 (and occasionally on 10.8). ... The Patch Management Curator compares the JSON file with the update to verify that the version number, dates, minimum operating system, App Name, and BundleID match.
