Its working for me perfectly fine. This is what it looks like in the plist preview for my config profile:

Use it and it works great. Using json setup. How did you deploy the icon in Jamf?

Hmm, it looks exactly the same for me.

I just added the filepath of the icon to the "Custom Logo" fields in the Preference Domain Properties of the config profile I made for the Support app. 

This is grasping at straws, but do you know the permissions on the png file?

Here's what mine look like:

Here's mine:

worth a shot to run the following commands to see if it helps:

Still no luck. Does the image need to be deployed to the machines in scope of the profile, by chance? Or does it just upload from my computer per the filepath in the config profile?

Definitely needs to be deployed. The config profile just contains the path to look for the file

Ah okay, that's most likely the issue then. I'll deploy the image, then report back!

That did the trick! I appreciate the help!

Hi Can you tell me exactly what you did then to get this to work? My logo will not load. Thanks in adavnce.

When I packaged the Support app in Jamf Composer for deployment, I dropped the image file in the folder and made sure the filepath of the image reflected what was configured in Jamf. You need to add the image file to the folder before creating the .pkg

Ahh okay, that stinks for me because I already used Jamf catalog to deploy the support app. So i guess I'm going to have to live with it.

But thank you for getting back to me on that. 

@hakimig - you don't have to "live with it"!

All you need to do is create an image and then package it.  

I use '/Library/Application Support/SupportApp/image.png' and then add that location to the Profile for SupportApp.

You can add/change/remove it at any time - even after deployment.

In that case--you could package the image by itself and deploy silently via Jamf, then edit your Support app policy to reflect the desired filepath for the image on the end user's machine, if that makes sense.
