I noticed the Screen Sharing icon when logging in despite it being disabled on my computer. After logging in, it didn't appear in the menu bar.

The Screen Sharing icon, on the login screen

What could be causing it? I tried enabling and disabling it via the command line but it persists.

# Enable Screen Sharing
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.screensharing.plist

# Disable Screen Sharing
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.screensharing.plist

I tried looking for solutions but only found confirmation that this is indeed the Screen Sharing icon.

What are the "Overlapping Squares" icon in status menu on login screen?


Found the culprit, nothing malicious. It's caused by an app called RetroClip. It enables "Instant Replay" type recording.

    Any idea how to identify the source? I might have the same problem. – jukben Sep 16 '18 at 12:21

    @jukben Sorry, no idea, I found out by trial and error. Try to identify any apps that for some reason need access to the screen is all the advice I can give. – sy'aY_A--0S5'iTH Sep 17 '18 at 10:07
