Translucent gray border around mac screen?

The problem is that the expose window is stuck. In order to force a refresh take these steps. 1. launch terminal 2. type killall Dock

For those unfamiliar with terminal, or how to launch it, do this:

type command + spacebar to open your search. Type "terminal" in the search and then "enter" to launch terminal.

You'll see a screen with a blinking cursor. Type:

killall Dock

Hit enter.

This happens because you have the "Show Desktop" trackpad gesture turned on. The gesture that activated it was to spread your thumb and three fingers. You can undo it by pinching your thumb and three fingers together.

Look under the "More Gestures" tab in the "Trackpad" section of the System Preferences for a video demonstration of how to do it, or scroll down to the "Show Desktop" section of this article: https://support.apple.com/en-us/HT204895

This is usually what the child/pet/alien has done to get the system in that state in the first place.

thanks this helped fixing the issue.

Only kids can cause this issue, apple should have some kids in the testing team 🙂

Could you please tell how you fixed it?

My baby kid turned this on by randomly pressing the keys 😁

Nevermind. I fixed it by restarting Dock application from Activity monitor.

can you post a picture? Maybe bad monitor bezel positioning in relation to the LEDs for the monitor.

bit more information needed, a picture would assist a lot.

Either way, full diagnostics would be needed at Apple., contact them for appt. for possible repair. 😊

Good afternoon,

I am having the same problem and I saw that you had fixed it. How did you do it?

Thanks,

A restart did not help me though. I spilled coffee and a few drops fell on the border of the trackpad. For some minutes the cursor moved randomly across the screen but then it stabilized. It was then I observed the gray translucent border up, left and down on the screen.

What can I do to get rid of it?

keyboard command, i just saw the picture. You ok? 😊

Thanks, this helped me

Hi guys,

You might wanna try restarting your laptop and then it should work. Well, it worked for me, don't know about you.😉

Thanks - this helped.

Another baby on the keyboard victim 😉
