Hi @aaron.kelley ,

Look at this post:
https://www.jamf.com/jamf-nation/discussions/14624/safari-s-trusted-internet-plug-ins-possible-to-set-w-casper#responseChild92598

Might profile some insight.

@rqomsiya I saw that earlier but I can't get those to work...maybe it is the layout of the way the user commented the scripts. I've tried different ways of typing them and nothing.

Have you tried a configuration profile with a custom payload? In our company it allows us to only open up sites we manage. Everything else is up to the employee. com.apple.Safari.plist is the domain and below is an example.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>ManagedPlugInPolicies</key>
<dict>
<key>com.macromedia.Flash Player.plugin</key>
<dict>
<key>PlugInDisallowPromptBeforeUseDialog</key>
<true/>
<key>PlugInHostnamePolicies</key>

@rqomsiya you already commented that...

I will second the use of a configuration profile. I deleted the com.apple.Safari.plist from a computer with Safari 10, Relaunched it and configured all the plugins to on for all sites, which is what we had set for Safari 9. Then I edit the .plist and stripped out all the bits un-related to the plugins. I found that in addition to the <Key>ManagedPlugInPolicies</Key>, I still needed the <key>PluginInfo</key> for each plugin, though I could delete everything except <key>plugInCurrentState</key> <true/>

So for the several plugins we wanted to have enabled, I have this:

<?xml version="1.0" encoding="UTF-8"?>

Initial testing is showing this working. I've had some complaints since Safari 10 of "This site says I don't have flash/java installed" Which seems to be how some of the pages react when the plugins are not enabled. I am hoping this configuration profile can solve this.

@chrischichester Hey, do you know if this still works in safari 12?

and what path are you applying the .plist to?

I am also trying to see if this works in safari 12...I will try and post back here if I find anything.

@McGinn Is it working for safari 12?

Apple removed NPAPI plugin support in Safari 12, which Adobe Flash was.
However... https://developer.apple.com/documentation/safari_release_notes/safari_12_release_notes
Indicate Flash is still supported?

@chrischichester it appears with safari 12, they had changed the location of the plist file, but it appears, the above does not work with it.
Have you happened to of been able to make it work? I would love to be able to whitelist a number of educational sites that use flash.
