Hi!

Have a look at this screenshot:

963d1495820393t-why-floating-display-scr

What is the smaller display box below the main one
that I can left-click-hold and drag around?

Why do I need this?

I don't have multiple screens.

I'm working on a new MacBook:

964d1495820655t-why-floating-display-scr

This causes the most annoying thing: wherever I've put
it, when I mouse into that area my mouse disappears off-
screen, causing me to have to mouse back up to see it.

I hate that!

Is there a way to turn this feature off?

Thanks!

That is meant to represent some sort of second display for the purposes of showing how that second display is "located" relative to your primary display. Your primary display will also have the little white bar across the top to represent the menu bar.

Are you sure you don't have some sort of second display? Besides it being some actual external computer screen, I believe it can also be if you have AirPlay turned on to display your screen on an AppleTV and it might also happen if you using one of those apps to have an iOS device (i.e. iPad or iPhone) act as a second screen for a Mac but I forget for sure (it has been a while since I used my iPad that way).

Edit: If you do have two displays, then there should be a second System Preferences window somewhere (it might be on the second display). If you click the "Gather Windows" button, that will bring the second System Preferences windows to the primary one and you can then see what it says across the top of the window. It will list the name/type of display across the top of each windows (i.e. in the screenshot, it shows "Built-in Retina Display", which is obviously for your laptop's internal screen). This might give a clue as to what the second display that the macOS is detecting might be. Based upon the relative size to what is shown as the MacBook display and the aspect ratio, my guess is an iPad sized screen of some sort maybe or maybe some sort of 4:3ish aspect ratio screen.

@ smax013

 

I don't have an iPad.

 

We've got 2 iPhone7+'s but have not set them up as alternative/additional displays.

 

(I don't even know how to do that!)

 

But I recently got a "USB-C Digital AV Multi-port Adapter, AVOTCH USB C Hub ,

3.1 Type C Hub , HDMI VGA Dual screen display Output, Card Reader, 2 USB

3.0 Ports and Gigabit Ethernet Adapter"

 

https://www.amazon.com/gp/product/B06ZYB5LL8/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

 

And it has HDMI and VGA outputs.

 

Your reference to "Gather Windows" showed up in my System Preferences > Display.

 

I couldn't figure it out but with your (most erudite and astute!) discussion I clicked to

"Gather Windows" and could now understand that what I'd previously seen and not 

understood was actually another display referenced to as the result of that multi adapter.

 

All I did was unplug the multi adapter from the USB-C (charging) port of my MacBook

and the 2nd display disappeared!

 

Kind of odd that even with no actual HDMI or VGA device plugged into that multi

adapter, the MacBook still read it as though there was (one or the other) attached

to the MacBook.

 

So ... thanks!

 

Now the mouse doesn't slide off the screen anymore!

 

Yay!!!

It is strange that the adapter would make Sierra think there was a display even when there was not an actually display hooked up to either the VGA or HDMI port on the adapter. If you want to be able to use that adapter and NOT have that issue with the mouse without an actual second display, you might need to try contacting the manufacturer of the adapter about the issue to see if they have anything to say. Avotch is not a name I recognize, so I don't know whether they will have good support or not.

Your previous advice plus the following resulted in ... SOLVED !!

From this reply on https://discussions.apple.com//message/31797991

For some reason, your Mac thinks you have an external display connected to it. If you pretend along with it, select Mirror, and the mouse should stay on your desktop where it belongs.

It's possible that resetting the NVRAM could resolve the issue: https://support.apple.com/en-us/HT204063, or booting into Safe Mode: https://support.apple.com/en-us/HT201262, or resetting the SMC: https://support.apple.com/en-us/HT201295


Many thanks to "tjk" over there for putting the icing on the cake ! 

 

And kudo's to @ smax013 for getting me onto the path of solving this one! :thumbup2:
