Our school is one to one in the middle school using MacBook air laptops (most are running Sierra but we will soon upgrade to Mojave). We are having issues with students using Imessage during class time. Is there a way to block all student devices from using the app?
By the way, I am a novice at these things.
Thanks for any help,
I go a full block on iCloud for student labs and block the preference panel with a policy. Don’t want multiple users etc with multiple icloud options. Keeps it tidier. Staff have a different policy and I let them, but they are usually only single players on machines
Mostly because I don’t want Apple to put something in place similar to iCloud lock on iPhone.
Sure most likely won’t, but the students can still access via iCloud.com
This may need to be discussed and inform people if you decide to do that though
Blocking access to iCloud prefs doesn't prevent users from logging in to Messages directly. Also, using a Restricted Software profile doesn't work quickly enough to prevent students from using the app. There's enough time between opening and the process being detected and killed for them to type/paste a message. I've remotely observed a student doing exactly this. Not to mention that they can just reply to the notification.
Just some feedback from experience: I was in a 1to1 iPad G-Suite district where we blocked everything that wasn't education related. Students would create a Google Doc and share it to their friends. School approved chat! And of course, O365 has the same problem.
Lesson learned - the technology department can only go so far to enforce what is ultimately a classroom management problem. It took me a couple of years to get administration to understand the real problem.
In addition to blocking the app with the restricted software settings, you can push out a script to enable Do Not Disturb. Since you can schedule DND via the System Preferences > Notifications, and you can hide that preference pane, I am looking into deploying that solution.
