Question: Black Box has appeared in my Macbook Screen


An opaque black rectangle has appeared in the center of my mac screen and I am unable to remove it. It seems to mirror documents on my screen with a small delay and i can't seem to remove it.

I have gone onto several community pages and I have tried all given fixes to this problem, the most populer fix being "command + F5" which brings up voiceover options which are all turned off and are not part of the problem.

One notice is that I can drag apps that are in my hotbar into the black box and it deletes them from the desktop.

Any help would be fantastic,

Thank you.

MacBook Pro, iOS 10.3.2

Does this occur for a different user, e.g., Guest?

Does this occur after starting up in Safe Mode?

Consider the possibility of a third party software conflict. EtreCheck can be used to investigate what is installed.

What is a "hotbar"?
