A good amount of users install Apps using their personal account since they have admin privileges on their Mac. Now, I know that we can't force updates since these apps weren't installed using self service but I was wondering if there's a way to get a list of App updates that are available from the App store.
You can view the installed MAS apps for each computer, but you have to go into each computer in the JSS to view it. It's not something that you can view otherwise. No advanced search criteria or anything of the sort. It is collected in the database though. I can't reach my JSS right now otherwise I would show you exactly where in the computer view it shows it in the JSS. But it is there.
