Managed TrustManager settings in macOS

Hi Everyone,

Hope all is well!

I've been running in to an issue where TrustManager settings in /Library/Preferences/com.adobe.Reader.plist don't apply. Specifically my goal in the Trust Manager is to block PDF files' access to all websites.

The key I'm using is iURLPerms with int - 0 as per here

What I've been trying in the plist is below. All of the FeatureLockdown keys seem to be working. Also, I'm not sure if there is a way I can use iURLPerms as a FeatureLockdown. So far in testing, using that key doesn't work in FeatureLockdown. Curious where I'm going wrong with this.

Thanks!
