Hello,
I not sure if anyone has worked this out or if its even possible. I am trying to add a custom schema for Microsoft Defender ATP "com.microsoft.wdav" to Jamf. I have worked out most of the setting which are required for the plist. The problem which I have got stuck on is how do you change an object type based on a selection. The below JSON will allow folders to be whitelisted but I need to be able to change the exclusions array from 3 fields ($type, isDirectory and path) to 2 fields ($type, name) based on if it's a folder or file.
Add advise is welcome.

Hi Stevie,
I started playing more with your schema and added some more to it. In addition to some remaining preferences that I added, I looked at the 'exclusions' and I think I have a solution, although not pretty. The idea I had was to include all of the possible keys, "$type", "isDirectory", "path", "extension", and "name" so that when configuring the preference you can add or remove the keys not needed. This allows me to specify an excludedPath, excludedFileExtension, and excludedFileName within the same schema. Let me know your thoughts!

Hi guys
I just started a few days ago to use defender on our M1 MacBooks. I have done the all the configurations from:
Set up the Microsoft Defender for Endpoint on macOS policies in Jamf Pro | Microsoft Docs
and
New configuration profiles for macOS Catalina and newer versions of macOS | Microsoft Docs
which are necessary. As configuration I use this json schema.
mdatp-xplat/schema.json at master · microsoft/mdatp-xplat · GitHub
Defender onboarding and the functionality works fine from the first time, but when checking the function for the threats
I am not able to save this settings. I have tested it maybe 20 times in each direction 🙂 but was never successfull. So in the end in the defender on the MacBook the buttons are visible and usable for the user.
Someone an idea if something is wrong with the json schema or have an tip how to disable this funcion on the client.
The issue is, that I can change it in the GUI, but it will be never written in the configuration.
I am thankful for any help.
Regards
J
