I noticed that macOS (Big Sur) is often telling me on my login screen that “your screen is being observed”.
I’m assuming that this is due to the fact that I allowed some apps top record my screen, but that explanation doesn’t quite make sense because
- the message does not always appear (but the permissions are obviously always on)
- the message states that my screen “is being observed”, implying that this is happening right now. But none of the apps that have permission is actually recording.
So if permitting at least one app to record the screen is a necessary condition for the message to appear, it is definitely not a sufficient condition.
My question: what (other) condition(s) must me met for the message to appear?
Bonus question: How can you check which app is “observing” the screen?
