On the lock screen in the top right corner of my Mac, there is a strange icon that disappears when I enter my password and log in. It would be great if somebody could tell me what that icon is, because it is making me start to worry. It is the icon in the left of this screenshot – like a pair of binoculars.
Best Answer
The binoculars icon may be present after ending a screen sharing session using tools like Google Meet or Slack, if those tools do not correctly shut down the screen recording functionality.
To eliminate the binoculars icon, just quit Slack and Google Meet. Restarting the computer should also work to make the icon go away.
