Red dot on Mac screen
If the red f do it means active recoding, how do I find out what / who is recording?
Question marked as
It means you have started a process, usually an app, that is actively recording.
What apps do you have running? Do you have a recording app set to startt automatically and run in background? A bit unusual, but I have seen it.
If it's not you doing the recording, and you should know if you initiated it or not, I suggest you restart immediately to stop the unwanted process. Do you have screen sharing activated and have you allowed others to use your Mac remotely?
