Managed TrustManager settings in macOS

Report · May 03, 2017

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!

Hi,

To block PDF files' access to all websites in Trust Manager, you can simply

Go to Preferences >> Trust Manager.
Under the section 'Internet Access from PDF Files outside the web browser', click on 'Change Seetings'
Select 'Block PDF files access to all web sites'.

Please let m know if this helps.

Thanks,

Shagufta

Hi Shagufta,

Thanks for the response. While that works for individual users, I have to deploy the same setting to about 500 users in our Mac environment, and lock the setting so users don't change the setting. That's why we're trying to using the manage preferences - which can be deployed to all users.

Thanks again!
